Petkit Eversweet Max for $90: This techy automatic fountain can be either cordless or battery-powered (lasting up to 83 days), and the drinking bowl is made of stainless steel, but the reservoir is plastic. Because of the shape of the basin with the chunky battery and reservoir bowl, it’s a little awkward to clean. The app logs every time a pet drinks and compares it over time to determine whether your cat’s drinking habits have changed. The app also keeps track of when the filter needs replacing and when you last added water. However, it doesn’t monitor or show you how much water is left in the basin; you have to check manually. The design also made it a bit difficult to clean and refill easily.
Enabot Rola Smart Pet Water Fountain for $50: This automatic fountain is cordless and runs on a rechargeable battery that lasts up to 60 days (although it can stay plugged in too). It has a wireless pump that uses magnetic induction—this pump was one of the easiest and most hassle-free to clean of all I tested. The fountain has a stainless steel top that holds a decent amount of water even when not running. Although the tank is plastic, and I’m wary of plastic now because of its propensity to harbor bacteria (plus it doesn’t keep water as cold). The app gives reminders of when the water’s low, the fountain needs cleaning, or the filter needs replacing, plus it automatically stops dispensing water and sends you a reminder to refill via app. It also logs the number of times your pet drank and for how long, monitoring hydration patterns over time and comparing the stats to average time used. A complaint I had is that this fountain wouldn’t stay on Continuous stream mode, even when plugged in, instead automatically switching to the Sensing stream.
Homerunpet Wireless Pet Fountain for $60: This cordless fountain can be used as a traditional fountain plugged in on its base, or can be detached and moved around the house with 30 days of battery life. I don’t love that this fountain is all plastic, but it’s easy to see water levels from the outside, the top and filter layers are super easy to remove, clean, and replace, and the wireless (basically silent) pump makes it a whole lot easier to clean. Plastic doesn’t keep the water as cold or clean as stainless steel, so you’ll have to clean it a lot more often. The fountain only begins bubbling when a cat (or human) approaches to save battery power, and there’s no option to control the flow (and no connected app). I like the wireless pump, but I’m really over plastic at this point.

Wonder Creature Cat Fountain for $20: My two cats have cycled through several water fountains over the past few years, but this no-nonsense version has been a stalwart. The inside is lit by a blue LED (bright enough to glow in the dark), and a clear viewing window on the side makes it easy to monitor the water level from afar. I also like the dishwasher-safe metal bowl and the fact you can remove parts of the yellow and white “flower” to create a fountain configuration your cat likes (waterfall, low bubble-up, tall bubble-up). The only major downsides are the fact it requires very frequent cleaning and filter changes due to the plastic body, and that there is no reservoir to hold water in case of power outage or pump malfunction. When I go on vacation I have to swap it out for an old-school gravity dispenser. —Kat Merck
Happy & Polly Gothic Cat Drinking Fountain for $60: If you prefer gothic decor to neutral blandness, this ghostly ceramic cat fountain from Happy & Polly may tempt you to bite. The water bubbles up out of the top of the ghost and pools on the ceramic top. It’s fairly quiet at around 35 decibels, but it gets loud when the water is running low, and I worry about the motor burning out, as the 1.5-liter capacity can run dry fast. While the ceramic finish is easy to clean, it is fiddly to take apart. You will want to clean it once a week to prevent it from becoming slimy, and you must change the filter once a month. —Simon Hill
Petkit Eversweet Solo 2 for $45: I love three key features of this fountain: The bowl sits on top of a wireless charging base, so you don’t have to fiddle with cables, it is super easy to clean, and it’s very quiet at around 25 decibels. A flashing light warns you when the water is running low, and you can check when the filter needs to be changed in the app. There’s an optional smart mode that pumps intermittently and a night mode to turn the light off. Pleasingly, all three of our cats drink from this fountain, though that does mean I have to refill it often, as it only holds 2 liters. —Simon Hill

Oneisall Stainless Steel Pet Fountain for $50: This drinking fountain is about as simple as they come. As it’s designed for cats or small dogs, it has a large bowl, but some cats will prefer that. I love the mostly stainless steel construction, as it’s easy to keep clean and less prone to dirt and bacteria buildup. You can even stick parts into the dishwasher to clean. This fountain can also hold up to 7 liters of water, so you don’t have to refill as often. It’s fairly quiet at around 35 decibels, but it gets louder when the water is running low (a red light warns you when it needs a refill). You should clean once a week and rinse the filter. The filter packs are relatively affordable at $15 for a pack of eight, and you need to swap them once a month. —Simon Hill
Petlipo Cordless Cat Water Fountain for $57: This all-plastic pet fountain sits on dock for easier tank cleaning and is rechargeable for up to 60 days of cordless power, has a wire-free pump, a large 2.6 liter capacity, and three customizable water flow modes (induction, timer, and continuous flow). The heavy duty filter is encased in a plastic cage and only needs to be replaced every 4 to 5 weeks. I had no issues while using this fountain, but at nearly $60, thats egregiously expensive for being made out of cheap (and bacteria-harboring) plastic. Although it’s a solid fountain, I’d spend less and grab one of stainless steel picks.

Petcube Ceramic Pet Water Fountain for $90: I really wanted to love this fountain; although its basin is plastic, it had a ceramic top, which is more hygienic than plastic (and I had never tested a ceramic model before), and the brand makes some of my favorite pet cameras. However, setup was a bit confusing, it took a long time to get the base charged to power the fountain’s water flow, and the sensor to begin water flow is only triggered from one side, making placement awkward. After a few days, it would only run while plugged in, soon its stream was barely strong enough to reach the top, and after just over a week it stopped working altogether. Also, it’s egregiously expensive for a pet fountain.

Cat Mate 3-Level Pet Fountain for $28: This tall automatic Cat Mate fountain sets itself apart with three tiers for cats who like to drink at every level. Cleaning the motor requires disassembly using tools and extended soaking. Because of the long distance the water has to travel, evaporation caused the water to need to be refilled about every other day. Plastic also harbors bacteria, and previous plastic models I’ve owned have had mold issues. The basin is quite large and sits flat. Because of this, some debris would sit in the bottom and front of the large basin rather than moving back to the filter system behind. The plastic material and lack of ergonomic gravity design caused this fountain to be dirtier than others.
Whisker City Free Fall Cat Fountain for $30: This huge fountain is better suited for dogs—with a large 150-fluid-ounce bowl and a waterfall design. Although the basin has a small splash pad to help offset the waterfall noise, this was one of the loudest fountains I tested. The evaporation from the waterfall-like system also caused me to refill it every other day. Because of the structure of the fountain, my cats had to bend their head at an awkward angle. They tended to avoid drinking from the basin because of that, and their heads got slightly wet from the splatter of the waterfall. The basin is also not angled so crumbs and debris sit at the bottom of the bowl.
Petkit EverSweet Solo SE for $26: This very simple, straightforward fountain has a square-shaped body, is translucent to easily see water levels from he outside, and has a nearly silent 25-decibel cordless pump to circulate water from the basin to the top level, where 60 milliliters of water is always available for drinking, even in case of power failure. The basin sits on a base and all parts easily detach, making it easier to clean. This fountain doesn’t have multiple modes or an associated app—you’ll have to check water levels manually. I noticed this fountain wasn’t as cold as some of the others, and because of the design of the top, debris often pooled in the dipped areas, which made me clean it often.
I used each of these for a week as my cats’ main source of water. As mentioned, I noted the ease of setting up, evaluated parts and filters, and generally compared the various types of water fountains—spigot, bubbling, or waterfall. Some flows were continuous and some were intermittent (my cats didn’t prefer intermittent). Cats may also be intrigued and want to play with the machine rather than drink, so be sure to give them time and keep another water source around until they are fully adjusted to the new gadget.
Cats sometimes struggle to consume enough water, which can lead to potentially lethal UTIs and blockages in male cats especially. This is one of the reasons vets are moving more toward encouraging owners to give their cat at least a partially wet food diet, as this helps them consume more moisture, especially since cats don’t naturally consume as much water as dogs. Unlike dogs, cats are generally quite particular in their likes and dislikes, and cats can see stagnant water as potentially harmful. (If the cat was in the wild, stagnant water has more potential for harmful bacteria). Cats are more drawn to moving water in nature, and these fountains help encourage them to drink more by emulating what they’re naturally drawn to.
While automatic water fountains are better for your cats’ overall water consumption, they do require a bit more work and money. Rather than refilling a bowl, these take a little more elbow grease—but it’s worth it for your cat’s health. Along with routine refilling and cleaning, you’ll need to disassemble the fountain to clean all parts, including using a brush for the bowl and tubes. You may also have to disassemble the motor to deep-clean because of mineral buildup. These also have different types of filtration cartridges in specific shapes for the brand’s fountains, which require you to buy and change out filters, usually monthly but sometimes more often.
Let’s be honest, a lot of these fountains are pretty much the same. I looked especially for the overall design—I am a fiend for stainless steel because of the potential of porous plastic harboring harmful bacteria. I also favor a wide reservoir without high sides to help reduce the chance for whisker fatigue. I prefer fountains that have a small basin reservoir of water available at all times, in case of low water levels or power failure. I took into account ease of setting up, refilling, and cleaning, as well as overall design. And of course, there were some that my cats took to straight away, and some they didn’t seem to favor as much.
After prolonged testing, I now look for these three things and encourage you too as well: a cordless pump for easier (and safer) cleaning, constructed from stainless steel so it’s more hygienic, and a window to monitor water levels (especially if it’s not connected to an app).
Analysis from GlobalData is forecasting that fixed wireless access (FWA) service revenue in Hong Kong is expected to increase at a “healthy” compound annual growth rate (CAGR) of 9.6% between 2025 and 2030.
The latest Hong Kong Total Fixed Communications Forecast set out to quantify current and future demand and spending on mobile services for the special administrative region of China. It noted that growth was being driven by Hong Kong’s extensive 5G network coverage and could also be attributed to local operators’ efforts to expand FWA services and position it as an alternative to traditional fibre broadband services for both residential and commercial sectors, meeting growing demand for high-speed connectivity in areas where extending fibre lines is challenging.
“High-density urban and suburban centres of Hong Kong create a strong business case for FWA services due to their cost-effective and rapid deployments without the complex infrastructure and civil work required for extending fibre-optic lines to such locations,” said Neha Misra, senior analyst at GlobalData.
“Competitive, feature-rich plans from the operators will also help drive its adoption over the forecast period. For instance, HKBN’s 5G Home Broadband Plan provides unlimited 5G broadband data (subject to a 300GB with a fair-usage policy) for HKD118 per month on a 24-month contract, along with a seven-day trial guarantee. The plan also includes a waiver of the HKD28 monthly administration fee and complimentary access to the basic HomeShield security plan.”
In addition to HKBN, the study noted that operators such as 3 Hong Kong and HKT are also using their extensive 5G networks to offer home broadband services, particularly in areas with limited fibre infrastructure. It cited HKT as recently having successfully deployed mmWave-based FWA to deliver ultra-high-speed internet to rural areas and outlying islands.
“Growing demand for FWA provides operators a strong revenue opportunity by expanding home and SME broadband without the high capital intensity of fibre roll-out,” Misra added. “By leveraging nationwide 5G coverage, introducing competitively priced service plans and bundling digital home services, operators can unlock higher ARPU [average revenue per user], accelerate market penetration in underserved areas and diversify beyond traditional revenues.”
GlobalData believes the Hong Kong government’s smart city initiatives will also open new opportunities for FWA, especially 5G FWA, which can deliver high-speed internet to power applications such as the digital economy, digital governance and e-health services, while supporting the city’s dense urban environment and digital transformation goals under the Smart City Blueprint 2.0.
The original blueprint was set out in December 2017, outlining 76 initiatives under six smart areas, namely Smart Mobility, Smart Living, Smart Environment, Smart People, Smart Government and Smart Economy. Blueprint 2.0 puts forth more than 130 initiatives that continue to enhance and expand existing city management measures and services. The new initiatives aim to bring benefits and convenience to the public so that residents can better perceive the benefits of smart city innovation and technology.
And thanks to a mention in Dan Brown’s new novel, The Secret of Secrets, the festival has gained even more global recognition. Just a few weeks after the release of Brown’s new bestseller set in contemporary Prague, viewers were able to see for themselves what drew the popular writer to the festival, which is the largest Czech and Central European showcase of digital art. In one passage, the Signal Festival has a cameo appearance when the novel’s protagonist recalls attending an event at the 2024 edition.
“We’re happy about it,” festival director Martin Pošta says about the mention. “It’s a kind of recognition.” Not that the event needed promotion, even in one of the most anticipated novels of recent years. The organizers have yet to share the number of visitors to the festival this year, but the four-day event typically attracts half a million visitors.
On the final day, there was a long queue in front of the monumental installation Tristan’s Ascension by American video art pioneer Bill Viola before it opened for the evening, even though it was a ticketed event. In the Church of St. Salvator in the Convent of St. Agnes, visitors could watch a Christ-like figure rise upwards, streams of water defying gravity along with him, all projected on a huge screen.
The festival premiere took place on the Vltava River near the Dvořák Embankment. Taiwan’s Peppercorns Interactive Media Art presented a projection on a cloud of mist called Tzolk’in Light. While creators of other light installations have to deal with the challenges of buildings—their irregular surfaces, decorative details, and awkward cornices—projecting onto water droplets is a challenge of a different kind with artists having to give up control over the resulting image. The shape and depth of the Peppercorns’ work depended on the wind at any given moment, which determined how much of the scene was revealed to viewers and how much simply blown away. The reward, however, was an extraordinary 3D spectacle reminiscent of a hologram—something that can’t be achieved with video projections on static and flat buildings.
Another premiere event was a projection on the tower of the Old Town Hall, created for the festival by the Italian studio mammasONica. It transformed the 230-foot structure into a kaleidoscope of blue, green, red, and white surfaces. A short distance away, on Republic Square, Peppercorns had another installation. On a circular LED installation, they projected a work entitled Between Mountains and Seas, which recounted the history of Taiwan.
Software development is associated with the idea of not reinventing the wheel, which means developers often select components or software libraries with pre-built functionality, rather than write code to achieve the same result.
There are many benefits of this approach. For example, a software component that is widely deployed is likely to have undergone extensive testing and debugging. It is considered tried and trusted, mature technology, unlike brand-new code, which has not been thoroughly debugged and may inadvertently introduce unknown cyber security issues into the business.
The Lego analogy is often used to describe how these components can be put together to build enterprise applications. Developers can draw on functionality made available through application programming interfaces (APIs), which provide programmatic access to software libraries and components.
Increasingly, in the age of data-driven applications and greater use of artificial intelligence (AI), API access to data sources is another Lego brick that developers can use to create new software applications. And just as is the case with a set of old-school Lego bricks, constructing the application from the numerous software components available is left to the creativity of the software developer.
A Lego template for application development
To take the Lego analogy a bit further, there are instructions, templates and pathways developers can be encouraged to follow to build enterprise software that complies with corporate policies.
A developer self-service platform provides a way for organisations to offer their developers almost pre-authorised assets, artefacts and tools that they can use to develop code Roy Illsley, Omdia
Roy Illsley, chief analyst, IT operations, at Omdia, defines an internal developer platform (IDP) as a developer self-service portal to access the tools and environments that the IT strategy has defined the organisation should standardise on. “A developer self-service platform provides a way for organisations to offer their developers almost pre-authorised assets, artefacts and tools that they can use to develop code,” he says.
The basic idea is to provide a governance framework with a suite of compliant tools. Bola Rotibi, chief of enterprise research at CCS Insight, says: “A developer self-service platform is really about trying to get a governance path.”
Rotibi regards the platform as “a golden path”, which provides developers who are not as skilled as more experienced colleagues a way to fast-track their work within a governance structure that allows them a certain degree of flexibility and creativity.
As to why offering flexibility to developers is an important consideration falls under the umbrella of developer experience and productivity. SnapLogic effectively provides modern middleware. It is used in digital transformation projects to connect disparate systems, and is now being repositioned for the age of agentic AI.
SnapLogic’s chief technology officer, Jeremiah Stone, says quite a few of the companies it has spoken to that identify as leaders in business transformation regard a developer portal offering self-service as something that goes hand-in-hand with digital infrastructure and AI-powered initiatives.
SnapLogic’s platform offers API management and service management, which manages the lifecycle of services, version control and documentation through a developer portal called the Dev Hub.
Stone says the capabilities of this platform extend from software developers to business technologists, and now AI users, who, he says, may be looking for a Model Context Protocol (MCP) endpoint.
Such know-how captured in a self-service developer portal enables users – whether they are software developers, or business users using low-code or no-code tooling – to connect AI with existing enterprise IT systems.
Enter Backstage
One platform that seems to have captured the minds of the developer community when it comes to developer self-service is Backstage. Having begun life internally at audio streaming site Spotify, Backstage is now an open source project managed by the Cloud Native Computing Foundation (CNCF).
While many teams that implemented Backstage assumed that it would be an easy, free addition to their DevOps practices, that isn’t always the case. Backstage can be complex and requires engineering expertise to assemble, build and deploy Christopher Condo and Lauren Alexander, Forrester
Pia Nilsson, senior director of engineering at the streaming service, says: “At Spotify, we’ve learned that enabling developer self-service begins with standardisation. Traditional centralised processes create bottlenecks, but complete decentralisation can lead to chaos. The key is finding the middle ground – standardisation through design, where automation and clear workflows replace manual oversight.”
Used by two million developers, Backstage is an open source framework for building internal developer portals. Nilsson says Backstage provides a single, consistent entry point for all development activities – tools, services, documentation and data. She says this means “developers can move quickly while staying aligned with organisational standards”.
Nilsson points out that standardising the fleet of components that comprise an enterprise technology stack is sometimes regarded as a large migration effort, moving everyone onto a single version or consolidating products into one. However, she says: “While that’s a critical part of standardising the fleet, it’s even more important to figure out the intrinsic motivator for the organisation to keep it streamlined and learn to ‘self-heal’ tech fragmentation.”
According to Nilsson, this is why it is important to integrate all in-house-built tools, as well as all the developer tools the business has purchased, in the same IDP. Doing so, she notes, makes it very easy to spot duplication. “Engineers will only use what they enjoy using, and we usually enjoy using the stuff we built ourselves because it’s exactly what we need,” she says.
The fact that Backstage is a framework is something IT leaders need to consider. In a recent blog post, Forrester analysts Christopher Condo and Lauren Alexander warned that most IDPs are frameworks that require assembly: “While many teams that implemented Backstage assumed that it would be an easy, free addition to their DevOps practices, that isn’t always the case. Backstage can be complex and requires engineering expertise to assemble, build and deploy.”
However, Forrester also notes that commercial IDP options are now available that include an orchestration layer on top of Backstage. These offer another option that may be a better fit for some organisations.
AI in an IDP
As well as the assembly organisations will need to carry out if they do not buy a commercial IDP, AI is revolutionising software development, and its impact needs to be taken into account in any decisions made around developer self-service and IDP.
Spotify’s Nilsson believes it is important for IT leaders to figure out how to support AI tooling usage in the most impactful way for their company.
“Today, there is both a risk to not leveraging enough AI tools or having it very unevenly spread across the company, as well as the risk that some teams give in to the vibes and release low-quality code to production,” she says.
According to Nilsson, this is why the IT team responsible for the IDP needs to drive up the adoption of these tools and evaluate the impact over time. “At Spotify, we drive broad AI adoption through education and hack weeks, which we promote through our product Skill Exchange. We also help engineers use context-aware agentic tools,” she adds.
Looking ahead
In terms of AI tooling, an example of how developer self-service could evolve is the direction of travel SAP looks to be taking with its Joule AI copilot tool.
When structure, automation and visibility are built into the developer experience, you replace bottlenecks with flow and create an environment where teams can innovate quickly, confidently and responsibly Pia Nilsson, Spotify
CCS Insights’ Rotibi believes the trend to integrate AI into developer tools and platforms is an area of opportunity for developer self-service platforms. Among the interesting topics Rotibi saw at the recent SAP TechEd conference in Berlin was the use of AI in SAP Joule.
SAP announced new AI assistants in Joule, which it said are able to coordinate multiple agents across workflows, departments and applications. According to SAP, these assistants plan, initiate and complete complex tasks spanning finance, supply chain, HR and beyond.
“SAP Joule is an AI interface. It’s a bit more than just a chatbot. It is also a workbench,” says Rotibi. Given that Joule has access to the SAP product suite, she notes that, as well as providing access, Joule understands the products. “It knows all the features and functions SAP has worked on, and, behind the scenes, uses the best data model to get the data points the user wants,” she says.
Recognising that enterprise software developers will want to build their own applications and create their own integration between different pieces of software, she says SAP Joule effectively plays the role of a developer self-service portal for the SAP product suite.
Besides what comes next with AI-powered functionality, there are numerous benefits in offering developer self-service to improve the overall developer experience, but there needs to be structure and standards.
Nilsson says: “When structure, automation and visibility are built into the developer experience, you replace bottlenecks with flow and create an environment where teams can innovate quickly, confidently and responsibly.”
