This website literally walks you through the coolest parts of the internet

https://static0.makeuseofimages.com/wordpress/wp-content/uploads/wm/2025/12/discovering-the-web-with-viralwalk.jpg

The World Wide Web is a massive universe that will take multiple lifetimes to completely explore. In fact, by habit, most people confine themselves to just a few selected parts of the web, usually Google, Facebook, YouTube, ChatGPT, and Instagram. That’s why I go out of my way to discover new and exciting websites.

I once discovered a website that allows me to listen to radio stations from around the world for free. But this time, I might have found one that’s even better: Viralwalk, a website that allows me to discover some of the coolest sites on the web. I’d give fair warning: don’t visit this website if you don’t want to waste a few hours.

Viralwalk is the anti-algorithm you didn’t know you needed

A website that lets you wander instead of search

One of the most authentic and refreshing experiences you can get on the modern web comes from landing on a website that has absolutely no idea who you are. One with no history, tracking, or algorithm waiting to nudge you towards what it believes are your favorite online destinations. That is exactly what Viralwalk does. It does not give you a search bar or a limited set of categories; you simply get the Start Walking button. Clicking it opens up the internet in a way you haven’t experienced for ages.

The first time I used Viralwalk, the experience I got was closer to wandering through an unfamiliar city than actually browsing the internet. I wasn’t looking for anything in particular, but stumbled upon actual gems.

One such gem was the Random Things To Do website. This site gives you ideas for things to do when you’re bored. Here, I spent minutes playing random games, then found drawing and painting prompts and projects to build in Minecraft. I would never have known that such a fun but simple site existed.

Exploring the web through moods instead of menus

The Walk, Chill, and Flow modes create different kinds of discoveries

Viralwalk gives you a unique way to explore the web. One of my favorites is the Mood category, which gives you a curated set of search moods. A few of the Mood options stand out and easily resonate with me. I love the Late Night Coding Vibes mood. One of the pins on this mood shows trending GitHub repositories. It became an invaluable resource that I use to find new open-source projects to test and write about. I only discovered it by chance, thanks to Viralwalk.

I also love the Digital Reading Nook mood. It has a helpful catalog of reading and writing tools, some of which I already know and use, and others that were new to me. It also has a few newsletters that I’ve now signed up for.

There are also a few other categories that I love. Flow gives a short overview of a bunch of random websites. You can keep scrolling through Flow until you find a website that catches your attention. Then click Open Site to visit it. You need to be logged in to use Flow.

Chill is also an interesting option on Viralwalk. It’s the option that allows you to relax with ambient visuals. When I need to take a break, I navigate to Chill and leave it in full-screen mode. The visuals constantly change, and it has a calming effect, perfect for a break after a long day’s work.

Collecting the gems you uncover along the way

Liked sites and albums make Viralwalk feel like a digital scrapbook

Viralwalk shows you so many interesting corners of the internet, and your first instinct is to save them. This is where the Like button comes in handy. There’s no browsing history that takes you back to familiar paths, but liking a destination saves it in your profile, and you can always come back to browse the list of liked sites.

It also has an Albums feature, which turns your discoveries into something more personal. I have an album of clever mini-projects and another for beautifully designed websites. Whenever I use Viralwalk and stumble on a website I like, I can tag it by including it in albums that are organized by theme. Anyone can browse my albums if I make them public when I create them.

A minimalist platform that quietly invites you to explore

Viralwalk’s design makes wandering the internet feel peaceful

After logging in for the first time, I saw a simple message: "Good morning." The interface had soft colors and rounded cards, and this calm layout set the tone instantly. It felt like I was opening a small creative studio rather than visiting a website.

It has a Quick Note panel on the welcome page, and I didn’t expect to appreciate it as much as I did. Mid-exploration, I keep referring back to Quick Note to jot down ideas, especially when my exploration sparks ideas that I’d love to revisit. Of course, this isn’t as elaborate as dedicated note-taking apps like Joplin, but it is a helpful little feature.

Viralwalk, however, limits you to 20 discoveries per day, and you’ll need to budget $8 per month if you prefer the pro service, which unlocks unlimited site discoveries in Flow/Walk. But the free plan is more than enough for me, since I don’t plan to spend my entire day on Viralwalk.

Wandering, surprise, and digital serendipity

Viralwalk uniquely brings the feeling of stumbling into something unexpected online. It perfectly recaptures the time when browsing meant exploring, not scrolling. It is one of the few websites I’ve stumbled upon this year. It’s just as much fun as that website that allows you to look through other people’s windows.

Snore!

The Kiffness made us laugh out loud with his silly remake of the 2011 Awolnation track Sail, which cleverly replaces the original’s synthesizer with the irresistible snoring sounds of a dog deep in slumber. Blame it on his floppy cheeks, baby!

Can This Simple Invention Convert Waste Heat Into Electricity?

Nuclear engineer Lonnie Johnson worked on NASA’s Galileo mission, has more than 140 patents, and invented the Super Soaker water gun.
But now he’s working on "a potential key to unlock a huge power source that’s rarely utilized today," reports the Atlanta Journal-Constitution. [Alternate URL here.] Waste heat…
The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that’s needed to keep the process going and electricity flowing is a heat source. As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more.
Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device’s ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about.
Inside JTEC’s headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that’s roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC’s vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat… For Johnson, the potential application he’s most excited about lies beneath our feet.
Geothermal energy exists naturally in rocks and water beneath the Earth’s surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity.
"You don’t need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC’s CEO and the former president of the pioneering internet service provider MindSpring, said he couldn’t reveal the customer, but said it’s a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said… On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon. "Johnson, meanwhile, hasn’t stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery…"

LEGO Stud Measure Tool

Until now, we thought the only tool for LEGO projects was the brick separator. Brick Science shows off another handy tool for custom LEGO builds. The Stud Measure is a retractable tape measure that’s marked with single stud increments on one side, and brick heights on the other. Its end piece is compatible with LEGO studs, so you can snap it in place.

I never expected an open-source app to beat IFTTT and Zapier — but this one did

https://static0.makeuseofimages.com/wordpress/wp-content/uploads/wm/2025/11/a-macbook-on-a-table-showing-the-huginn-automation-app.jpg

I’ve used more automation platforms than the average person — IFTTT (If This Then That), Zapier, Make, n8n — plus a few obscure ones that never went past beta. What every one of them did was box me into templates. This throttled my workflow and failed to show the real strength of premium tiers. I settled for living within their limits, even when it meant holding back my ideas.

A friend recommended Huginn, and I was intrigued by how fundamentally different it is. No glossy shortcuts, no paid add-ons, just raw access, full ownership, and the satisfaction of finally building my own automations rather than renting someone else’s. It’s surprising how it subtly outperforms some of the big names. It’s become one of my favorite free automation tools.

Why Huginn’s architecture outclasses Zapier and IFTTT’s paywalled features

If you used IFTTT or Zapier, you’re familiar with the trigger-and-action structure. Huginn’s implementation is different: it builds workflows using a continuous agent-to-event-to-agent chain. This approach delivers an immediate advantage with multi-step logic, conditional paths, and data shaping as core, fundamental, and free parts of Huginn. Typically, these are paid features in several tools, including Zapier and IFTTT.

The agents are small workers that produce structured JSON events. These events produce scenario chains that act like small automation ecosystems that can branch, merge, and loop through other agents, rather than acting as isolated tasks.

Huginn allows unlimited chaining, dynamic routing, and even native scripting, replacing expensive features in Zapier like Webhooks by Zapier, Code by Zapier, and Multi-Step Zaps, without limiting how often or how deeply you automate.

OS

Linux, macOS, Windows

Price model

Free

Huginn is an open-source, self-hosted system which allows you to build automated tasks online using "agents". Agents can monitor websites, gather data, or trigger actions.

You fully own your data, your workflows, and the entire stack

The freedom of self-hosting—and the responsibility that comes with it

Huginn runs on your machine, making it fundamentally different. Triggers don’t pass through third-party companies, events aren’t logged on other platforms, and API keys don’t leave your computer. You don’t get this level of sovereignty from other platforms, which is ideal if you’re handling sensitive data.

However, owning the entire stack means you take responsibility for upkeep, which could be updates, security patches, Docker images, and backups. While this isn’t difficult, it’s a tradeoff worth mentioning. Commercial tools handle the upkeep but take away your control.

Huginn’s freedom extends beyond privacy. You can modify an agent if it lacks a feature or build an integration the platform needs if you have the skill. The only cost incurred is the server it runs on, and this alone can wipe out entire Zapier billing categories for heavy automation users.

Native scraping, parsing, filtering, and unlimited Webhooks

Huginn thrives in certain aspects where cloud-based automation tools quietly impose limits. For instance, its WebsiteAgent can scrape sites, crawl APIs, extract structured content, and run full JSONPath queries—things IFTTT doesn’t support, and Zapier will only accommodate in high-tier plans. It also offers Liquid templating so you can transform, reformat, or compute values before passing them on.

I can use unlimited Webhooks on Huginn for free, even though I had to pay for a similar feature on Zapier. This makes it possible for me to stitch workflows together or connect external apps without restrictions.

Advanced filters are heavily monetized features in Zapier, but with Huginn’s TriggerAgent, I can evaluate conditions, filter events with regex, or run small JavaScript snippets to decide which agent receives the next step.

Huginn unlocks a new category of personal automation

Workflows that literally cannot exist on Zapier or IFTTT

After building your first multi-agent chain, you will discover the true potential of Huginn. You can create a multi-branch pipeline that scrapes sources, filters by keywords, cross-references a spreadsheet, and sends a curated digest. It goes beyond merely replacing a Zap or an applet and constructs workflows that your favorite cloud platforms can’t execute, even if you’re on the premium plans.

A real example could be: RssAgent -> TriggerAgent -> DataMiningAgent -> GSheetsAgent -> EmailAgent. Assuming the sentiment analysis step is even possible with Zapier, it will require several Zaps and connected accounts, and also numerous billable tasks. IFTTT wouldn’t get past the first filter, but Huginn handles this kind of complexity easily. So, aside from saving money, Huginn unlocks degrees of automation that commercial platforms aren’t built to handle.

Setup feels intimidating — but using Huginn is surprisingly straightforward

The honest reality of installation, maintenance, and documentation

Huginn’s interface is pleasantly straightforward, but getting it all ready to use requires a mental shift. You’re spinning up your own automation server rather than signing in to a cloud dashboard. It was a similar process when I set up Nextcloud after ditching Google Drive. Docker makes it easier, even though you still have to deal with logs, restart containers, and manage database backups.

Just like several open-source projects, documentation for Huginn isn’t as elaborate as mainstream options like Zapier or IFTTT. You’ll be relying a lot on GitHub issues, community discussions, and reading agent READMEs directly in the repo—all part of the open-source experience.

Once you get it up and running, it’s straightforward to manage and stable. You can easily inspect events or catch errors, and debugging feels natural. You can version-control your complex setups with Blueprints, and you can automate Huginn itself with the CLI/API.

Huginn changes how you think about automation

Huginn completely changed how I think about automation. Rather than stitching together pre-approved actions, I imagine what’s possible when nothing is off-limits and when no features are locked behind paywalls.

Huginn gives you control and total ownership of a very powerful system. After experiencing this level of control, services like Zapier or IFTTT feel less robust, and Huginn has become an integral part of my productivity tools.
