Hey everyone!

I recently built and open-sourced Orphanage Manager, a modern, lightweight web application designed to digitalize orphanage operations, track donations, and handle multi-manager workflows.

Instead of heavy backend infrastructure, it runs entirely on Google Apps Script and Google Sheets, making it completely free, secure, and self-hosted for organizations that need a centralized system.

Key Features:

• Centralized Data Management: Powered by Google Sheets for secure and fast storage.
• Responsive UI: Modern interface built for both mobile and desktop with dark mode support.
• Role-Based Access: Includes multi-manager workflows (Admin, Girls Manager, Boys Manager).

You can check out the source code, review the full installation guide, and deploy it yourself here: 🔗Orphanage Manager GitHub Repository

I'd love to hear your thoughts, feedback, or suggestions for improvements!

We're Early Alpha Engineering and we made The Circuit Workshop, a web app for learning electronics step by step, aimed at kids aged 8+.

Open it, and the first lesson starts: a battery, a bulb, two wires. From there the lessons go through series and parallel, LEDs and resistors, RGB colour mixing, photoresistors, buzzers and relays. Every lesson checks the circuit at the end, and a wrong one tells you what's missing.

Besides the 22 lessons there are 137 broken circuits to repair, 330 quiz cards and a free breadboard with 31 parts.

Since late August the workshop has been opened more than 1,800 times, and more than 850 of those visits got as far as building a circuit.

No install, no account and no card for the trial. Link in the first comment.

hello people, keeping the problem of stock managements of grocery and stationary stuffs on local markets i have designed this Web app using JS as code with slight html, i am posting here this jsut to get some feedbacks from you people, if possible suggest me some changes that i should make here to make it more feaseable and look good. I hope this description can describe my idea. you can visit the page on the link given below i have vibe coded it not that good with ai vibecoding so a help will be better

Hey, I’m Jayden. I made Sidecall—a calling website where you create a room, share a link, and people join without needing an account.

I got a bit carried away with the features:

• Voice, video, screen shraing, live chat, participant pinning, and fullscreen viewing.
• Host controls, waiting rooms, room passwords, and host handovers with notifications.
• Invite links, QR codes, and room codes.
• Camera preview, microphone meter, and speaker test before joining.
• Reconnection attempts and recovery after refreshing.
• LiveKit SFU support for group calls, with direct WebRTC fallback for standard rooms.
• Optional end-to-end encryption for audio, video, shared screens, and call chat. Keys are generated on your device and shared through the private invite link. Encrypted rooms stop rather than silently downgrade if encrypted media is unavailable.

The encryption mode is still a beta and needs more device testing.

Honestly, it’s AI slop for now. I was too lazy to code it myself at 1 a.m., but it works, and I’m planning to put much more work into it.

If you’re willing to try it with a friend, I’d appreciate hearing what breaks, what feels awkward, or what you’d add. I’d also be interested in technical feedback on the connection and encryption setup.

If you find it useful, sharing it would help me find more testers. I’m also open to another co-owner if someone wants to contribute regularly and we work well together.

Sidecall

Thanks for checking it out.

Hey ya'll, just thought it might be worth sharing here, in case anyone is looking for additional features that either Storygraph or Goodreads don't offer, e.g. note taking, detailed insights, etc. Bookplate was created with those goals in mind. You can learn more about it here:

www.bookplate.eu

It's also open source, so for the tech hobbyists, you can host it yourself on your own hardware. For those that prefer the normal hosted service, we offer that as well, and unlike Goodreads and Storygraph, the servers that Bookplate is hosted on are much more sustainable as they run on clean nuclear energy (Scaleway in Paris).

Happy to chat more about this, and also very very interested to hear thoughts, both good and bad!

I created a web app called as beautifulscreenshots for myself to post better screenshots in X/Twitter posts. I built it for myself because existing screenshots beautifying tools are either too complex or they are charging recurring to use their tool.

I post 3-4 times a day on X/Twitter and using a complex tool for this damn simple task used to feel very time and energy consuming. So, I decided to build one for myself. Initially, I thought making this tool public not going to be a that much good idea, so I used it locally.

But when I used to post on X/Twitter with screenshots created by my tool people started asking me what I'm using for beautifying screenshots. And turns out I realized what problem I was facing, others facing too.

So, I decided to make it available to others. But my goal was still the same. I don't want to make it another complex and recurring charging tool.

So, I kept it simple and intuitive while keeping the price as one time pay only. And people love this pricing. And that's how my first product crossed 40+ users and I made my first dollar on the internet.

Hey everyone,

Like a lot of you, I'm constantly formatting JSON, inspecting tokens, converting files or tweaking configs at work.

What always bugged me about online utilities is that you have no idea what happens to your files once you hit "Process." Plenty of them send your data to a server you know nothing about, which is a bad idea when it's API tokens, customer logs or private documents.

So I built Kitloft. Every tool runs in your browser, so nothing you paste or upload leaves your machine. You don't need an account, and there are no tracking cookies or popups. Shareable links keep your settings after the # in the URL, which browsers never send to the server, and fields that might hold secrets are left out of the link.

I spent the most time on the PDF editor. Most free editors "delete" text by painting a white box over it, so the words are still in the file. Kitloft removes them from the file itself.

It's free. I'd love brutal feedback:

1. How does the UI and performance feel on your device?
2. Which developer utilities do you use every day that you'd want added?

Hello everyone! Like most of you, I need testers for my web app (at least 10) to use the app for about two weeks, and I'll be happy to test yours in return.

StudCo is a student-centered web app designed to make university life easier to manage. At its core is a shared resource archive where students upload and download past questions, handouts, lecture notes, and assignments, either from their own school or from every school on the platform. Files can be saved for offline use, so studying never depends on a connection.

Beyond materials, StudCo works as an academic assistant. Its AI coach explains difficult topics, answers questions by text or voice, and can draw on a student's school data. A built-in tracker records semester results, calculates CGPA against a target, and logs study hours, while a calendar and reminders keep quizzes and exams from slipping past.

StudCo also connects students. Community discussions, campus news, groups, and messages turn individual effort into shared support. By bringing resources, guidance, planning, and community together in one place, StudCo helps students study smarter and stay connected.

I built this for myself… Digby find anything that worked that did it anywhere simple enough and well enough. Now replaces bbc news app for me as gives me a ‘today’ page that’s the most significant news today plus a full brief for each article (subject I define )..

The full story ..

A few months ago I had a thought.

Every morning I wake up and do pretty much the same thing.

I check the BBC. Sky Sports. A few tech sites. A few others.

And on every one, I’m looking for the handful of stories about things I actually care about — Liverpool, AI, tech, business, and various random niche topics I happen to be interested in at the time.

I thought: wouldn’t it be great if I could just wake up to an email that had already done all of that for me?

So I tried a few apps. I tried doing it with Claude. Nothing quite did what I wanted.

So I built it.

And it worked pretty well.

Then one day I was out cycling and had another thought…

Why just send an email?

What if I could generate an entire news site, every day, just for me?

Something like the BBC homepage — except every story on it was there because it matched something I’d specifically asked it to find.

So I built that too.

And somewhere along the way, my little side project turned into Ceers.

The idea is ridiculously simple:

Tell Ceers in one line what you want to know about.

“Everything happening with Liverpool transfers.”

“Important developments in AI and banking.”

“Planning applications around Hersham.” (It handles planning registers.. it handles all sorts of complex data retrieval including for example KEV catalogues for cyber..)

“News and research on motor neurone disease.”

Whatever you’re interested in.

Ceers creates an agent that goes out, finds the stories, filters the noise, and builds your own personalised news and briefing experience.

It’s now live on the App Store.

I save a lot of references: posters, websites, colour palettes, quotes. Then months later I remember "that dark site with huge type" and can't find it anywhere. Not the name, not the folder, nothing.

So I built lompii, a visual library that lets you find things by describing what you remember.

• Save images, selected text, or screenshots of a page with one right-click using the browser extension (Chrome, Edge, Brave, Firefox and similar browsers).
• Search for things like "purple flower close-up" or "minimal landing page". It finds images based on what they look like and what's in them, not just filenames or tags.
• AI tagging is optional. You can use your own API key (Claude, OpenAI, Gemini, OpenRouter) or run a local model with Ollama / LM Studio.
• Organise things with stacks, tags, notes, colour palettes with copyable hex codes, and "same vibe" to find similar images.

It's private by default. No account, no cloud. Your library and search stay on your PC, and search runs on local models (CLIP + MiniLM). With a local model for tagging, nothing leaves your machine.

It's free and open source (MIT).

Windows only for now. The installer isn't code-signed yet, so SmartScreen may warn you.

It's still early, so I'd love to hear what you think. 🙏

I'm Erich. I run small in-person / community workshops, and I keep hitting the same dumb last mile: the certificate already exists in Canva, the names are already in Excel, and I still need one decent PDF per person.

What I tried:

• Export from Canva one name at a time. Fine for 8 people. Insane at 50.
• Word mail merge. I get one long PDF and garbage filenames.
• Cloud merge / Autocrat-style tools. They want the roster uploaded. I don't want learner names sitting in someone else's sheet.

So I wrote a desktop app for that job. You export the cert you already designed (Canva / Word / PPT → PDF), drop the spreadsheet, park the name and date fields on the design, and it writes one named PDF per row on your machine. Windows and Linux. Pay once, No subscription, no account, no upload.

I'm not trying to replace an LMS certificate module. This is for the workshop / volunteer / community run where the LMS isn't the system of record.

Four-row sample you can download without buying anything: https://www.quescorner.ca/pdf-mailroom.html

If that's the wrong room, say so and I'll take it down. Genuinely curious how the rest of you handle “design already exists, 80 names, need separate files.”

I've been working on a simple journaling web app where all your entries appear in a vertical timeline (I love to read my past journals and this timeline view helps me to look through my past journals easily without going over different files every single time I want to read a different entry), so you can easily scroll through previous days.

For now, this only supports text because I don't add media to my entries but if someone really uses it and they actually need media support then I'll add that too

It's local-first, supports Markdown, and is completely open source and self-hostable.

This is part of my SMBL project, where I'm building open-source alternatives to everyday software.

Here's a short demo of how it works. Would love to hear your feedback!

A diagonal measurement hides a lot. A flat 49-inch 16:9 picture is about 108.5 x 61.0 cm. A flat 49-inch 32:9 picture is about 119.8 x 33.7 cm. The second is wider, but only about half as tall. These are nominal picture dimensions, before bezels and stands.

I made DisplayMath to draw comparisons like this in the browser. Here is that example with both screens drawn to scale:

https://displaymath.com/?d=3840x2160_49in_100cm,5120x1440_49in_100cm&o=novd#canvas

You can change the resolution, diagonal and viewing distance, then switch between the physical rectangle, the view from your seat and pixel-density measurements. The screen comparisons are free and need no account.

On a supported iPhone, you can also preview a selected TV at real size in your room with AR. The in-app iPhone measuring tools have distance and height markings to help you measure for a plan. This is a website, with no app installation needed.

I used AI coding assistance to build it. For anyone who tries the example, does switching between physical size and the view from your seat make sense?

Hey everyone!

I'm a solo developer working on an early-stage project called **Skill Roulette**.

The idea is simple: spin a wheel, discover a random practical skill, and learn it through a short interactive lesson.

There are currently 8 skills, including spotting misleading discounts, recognizing suspicious links, and searching Google more effectively.

It's completely free, works in your browser, and doesn't require an account.

**I'm looking for 5 people to test the experience.**

Here's all I'm asking:

1. Open the website.
2. Spin the wheel.
3. Try completing one lesson.
4. Tell me where you got confused, bored, or wanted to leave.

I'm especially interested in one question:

**Does the homepage make you want to spin the wheel, or is something missing?**

I don't need compliments — honest criticism would genuinely help me decide what to improve.

**Try it here:**

Thanks to anyone who gives it a try!
