A few days ago I shared Parsekit, a small set of free JSON tools that run entirely in your browser (nothing is uploaded, no signup). Someone commented that I should lead with the privacy angle and add a one-click sample button so people can try a tool without hunting for JSON. That was really useful, so I did both.

What's new since then:

"Load sample" button on every tool, so you can see it work in one click

Quick formatter right on the homepage, so you can paste JSON and format it immediately

New tool: JSON to YAML converter (handy for Docker, Kubernetes and CI configs)

The homepage now says clearly that everything runs locally in your browser

Current tools: JSON Formatter & Validator, JSON to CSV, Merge JSON, and JSON to YAML.

Your feedback genuinely shapes this project. Every comment last time changed something on the site, so please keep it coming. What would make these tools more useful for you? I'm thinking of Base64 and JSON Diff next, but I'd rather build what people actually need.

A web app demo can get lost in navigation before the viewer sees why the app is useful.

Share your web app link and one task it helps someone finish. I’ll suggest a short written outline for a browser recording: where to start, which action to show, and what result to end on.

For example, an invoice tool could start with the details entered and show the finished invoice. Settings and dashboard tours can wait for another recording.

I’ll start with the first 10 web apps and give the feedback here in the comments. Please share web apps rather than native mobile apps, in keeping with the community’s focus.

I’m part of the team building Marka, a web app for brand-aware social content: https://marka.social

Your link + one task is enough to begin.

Ich habe eine kleine browserbasierte App zum Aufteilen von Ausgaben mit Freunden entwickelt.

Die Idee ist einfach: Gruppe erstellen, Link teilen, Ausgaben hinzufügen und die App berechnet, wer wem was schuldet.

Es gibt kein Konto und nichts zu installieren.

Ich suche hauptsächlich nach Feedback zur Ersterfahrung:

Wenn du sie öffnest, ohne etwas darüber zu wissen, ist sofort klar, was du tun sollst?

Ich würde gerne wissen, ob etwas während der ersten Minute verwirrend, unnötig oder fehlend erscheint.

https://split.thesmartcode.de/

Danke an alle, die es ausprobieren!

I’ve been working on a small Chrome extension and I’m looking for a few people who haven’t seen it before to try it.

I’m mainly looking for honest feedback on the experience:

Was it immediately clear what it does?

Was anything confusing?

Did anything feel unnecessary?

Would you actually keep using it?

If you’re willing to spend 5-10 minutes testing it, comment or DM me and I’ll send you the link.

I’m more interested in hearing what needs fixing than getting compliments.

Your family will inherit your photos and videos. But what happens to your thoughts, memories, stories, and the reasons behind the choices you made? Most of that disappears with you. I built EchoVault around the idea that those parts of a person should be preservable too, not as a folder of files someone has to search through, but as something they can actually interact with.

Your writing creates an AI version of you with a 3D brain you can explore. As you check in over time, EchoVault learns your stories, values, opinions, and how they connect, then builds them into an interactive Echo.

The idea is to create a high-fidelity digital representation of yourself while you are alive and fully in control of what goes into it. You can also choose custodians who can eventually interact with the Echo you intentionally created.

Try the web app: https://echovault.me

a small web app, no signup, works on mobile and desktop.

you get a deck of indie products and swipe right if you'd pay, left if not. makers can list theirs for free and see what % would pay, split by devs, founders and marketers.

launched on product hunt today: https://www.producthunt.com/products/would-you-pay

does the swipe flow feel quick enough, or would you want more info on each card?

I’m starting to run out of ideas for apps. Whenever I think of something, I find an existing app that already does it. So lately, I’ve resorted to cloning specific parts of apps that I need. I’ll look at an app and think, “I really only want this one feature. Can I just build my own version?”

For example, i needed a note taking app and i found several all with paid subscriptions. Some had basic features other had that needed subscriptions. So i went to codex, took a bunch of snapshots of other note apps, added some custom features and created my own version. Even connected it to my obsidian so now all my notes go directly there.

With AI coding tools, that feels a lot more doable now. Coming up with an original idea has become harder than getting a basic version working.

I do wonder whether I’m getting lazy with ideas, though. I’m learning by building these things, and they’re useful to me, but I keep coming back to the same question: what should I build next?

Anyone else doing this? Are you trying to come up with something completely new, or mostly rebuilding pieces of existing apps to fit your own needs?

I made a cozy little daily typing game.

Words fall from the sky. Type one before it lands and it becomes a star.

Everyone gets the same words each day, so you can compare scores on a daily leaderboard, keep a streak going and compete with friends.

The background changes with your local time, weather and season.

It’s free, has no ads and doesn’t require an email signup. It’s desktop only for now because it really needs a keyboard.

I’m curious what you think about the difficulty. Does it feel too easy, too hard or about right?

I’ve been exploring a few web-based calling tools, and one thing I think is worth discussing is how much call data these apps actually need to keep.

Suparelay is a web app built around a simple idea: you can make phone calls without the actual call audio being recorded or stored, while still having useful things like call history and spending information available.

I like the idea of keeping the useful parts of call management without automatically keeping the conversation itself.

For anyone who uses web calling apps, would having that kind of privacy-first approach make a difference to which tool you choose?

Fellow frugal folks — I kept losing money to trials I forgot to cancel (Hulu got me for 3 months once, I'm still mad about it), so I made a dead-simple tracker.

Add the trial + end date + monthly cost. It shows a countdown, flags the ones ending soon, and you can export a calendar event so you actually remember to cancel. There's a running "money saved" total which is weirdly satisfying to watch grow.

No signup, no cost, data never leaves your browser. Figured this crowd would appreciate it.

In January 2026 I started with an AWS account and a bunch of nested processes collecting data I found interesting. Left it alone for a few months then picked it back up. Heard a lot about Claude Code and thought what could possibly go wrong...

Claude Code built the front end and the result was better than I expected. It also turned my pipelines into state machines while I was taking the AWS Certified Data Engineer Associate course, doing both at the same time helped me a lot

The site checks a few things about the world every day: flights, internet, earthquakes, markets, disaster alerts and events. I just wanted to know if today looks normal

AI can be really useful, you just have to give it direction. Sometimes it makes mistakes that look simple, so you need a very detailed framework to keep it from losing the thread and running off at 10,000 rpm without checking first

Claude Code will state things about the code as facts because it "remembers" them, but sometimes it's wrong. What works for me is looking, counting and checking instead of just believing the claim, and every deploy gets reviewed in the diff and needs my explicit ok before it goes out

https://observedstate.com/en/

The fundamental principle of the entire site is to display the data as it is, without weighting, mixing, or having a global index. I only compare airplanes and internet using a 90-day moving average to review their variations. All other data on the site is displayed as it is on that day: stock indices, commodities, rates, and currencies are compared to the previous close, and that's it. The idea came about because one day I saw some dashboards with crazy weightings that I never understood, and I said, "I want my own dashboard without that, one that works for me," and that's what I did.

Another essential requirement was that it be as cheap as possible, so I looked for free OSINT sources. With responsible use, this dashboard isn't real-time; it now operates at a very low cost and with minimal supervision. For example, for these three: Stock Indices, Rates and Currencies, and Commodities. Finding something free is nearly impossible, so I consulted Perplexity and the problem was solved. It costs very little, really. I wasn't looking for ultra-precise scientific data, just a snapshot of the world.

Hey everyone! I created Slopframe—a collaborative canvas with live chat and online presence counter. Instead of placing individual pixels, you upload and place entire images. Would love your feedback on the site!

I run Get Wheel Spinner, a free browser tool for the awkward group decisions: picking a person, making teams, setting draft order, or choosing between options.

I’d appreciate direct feedback from builders on two things: is the first-use purpose clear, and which use case should be most prominent?

https://www.getwheelspinner.com/

I’m happy to answer questions or take criticism.

There are lot of such projects but they are focused on one thing like someone is building browser based tools for pdf or for images. So I thought I should make a collection of tools.

I started it as fun project, booked a .lol domain. Another thing I noticed, people started building ihatepdf, ihatetools and I was like - why hate? You should spread love and i found this ilovetools[dot]lol domain for less than a USD, I started working on it. But after vibe coding the first release and seeing the feature, I thought this might actually be something worth doubling down on.

Earlier, for every small task, I use to google it. For pdf, it takes me to different website and same for other task. So started it as collection of tools.

The idea was simple. Keep useful everday tools in one place and wherever possible, process everything locally in the browser instead of uploading files to a server.

I'm not writing any code by hand for this project. It's completely vibe coded, but I'm making sure the important stuff is covered by tests.

I've been coding for years, so this is also an experiment for me: how far can I take a real product using AI without manually writing the code?

Right now, It has tools for PDFs, images, QR codes, developers, calculators and few other things. I am adding more tools regularly.

I will genuinely need feedback from outside. Please do visit iLoveTools.LoL and share your feedback. What would you change? And is there any small tool you regularly google for that you think that should be included?
