At work, I often need to submit PDF documents, but the photos I take on my iPhone are in HEIC format. To make it easier to convert HEIC to PDF, I developed a website: https://heictopdf.run/. It allows you to batch convert HEIC files to PDF online, with all processing done in the browser—no data is stored on the server.
I recently got a pen plotter. I've been working on making my own implementations of algorithms to convert images to vector graphics for plotting. Things like cross-hatching to fill in dark areas, or spirals or flow fields, etc. I also found out about vpype[1] recently which does some cool things in this area.
I'm building the JavaScript version of Semantic Kernel: https://kerneljs.com
> Semantic Kernel is a lightweight, open-source development kit that lets you easily build AI agents and integrate the latest AI models. It serves as an efficient middleware that enables rapid delivery of enterprise-grade solutions.
A reverse image search to detect dirty xtc pills. https://pillscanner.app/
I'm building a PyQt6 desktop app to create XML sitemaps for website maintainers such as myself. I got annoyed with the free online tools that are available, and also want to play with building desktop apps with Qt, and improve my Python programming skills. This seemed like a fun hobby project that has some value for me at work too, so I am not just building it to forget about it later.
Started on a dependency-free (including manual object file creation, excluding manual linker) single-pass C compiler with a goal of it being self-hosting. Spawned after my previous project (single-pass Wasm JIT) started to plateau a bit and wanted to start something more "full-stack compiler"-y.
The cursor for sales: a co-pilot for founders who sale or AEs that analyses all the channels the sale happens in (email, meeting minutes, LinkedIn, slack etc) and able to take actions like writing followups or detecting hot leads. Helpful for startups who feel pain in their mid-funnel. https://closer.so
I submitted my travel planning web application [1] few weeks ago as Show HN [2] and it received tons of feedback and ideas that resonates with me. So I'm still working on it :)
* I'm working on the Mnyify(https://mnyify.com), a AI expense tracker app. * I would ship another Sass web application that will minimize the notification this year. * I'm working on the CJK message display on the Meshtastic device, it's pretty much done, but still has a some refinement need to do.
Meshtastic is fun!
The free Shopify directory (240k stores and 580m products at the moment).
I'm building an AI for Customer Support.
Here's the summary: - read all your sources - public websites, docs, video - answer questions with confidence score and no hallucinations with citations - cut support time and even integrates directly into your customer facing chatbots like Intercom.
Still deliberating on the business model. If anyone would be interested in taking a look, I would love to show you.
I am working on a tool that lets you create data visualizations with prompts.
When I was in college I really hated searching through all the excel and google docs menus to add trendline, change colors, gridlines, etc (and sadly I didn't have the agency to learn matplotlib or seaborn). I figure others might hate this too, and it would be so cool to have csv + prompt -> exportable svg chart
I'm working on Hispi (https://www.hispi.app) which is an AI powered tool to help people design custom jewellery (starting with rings). We use some image models and some text models to build the ring, estimate materials etc and then work with real jewellers in London to actually make and ship them!
https://any-l.com I have an interesting terminal for you to play with.
I'm writing a series of tutorials on solving algorithmic leetcode-like problems in a modern, scalable way. I use JAX library for python, so the solutions work on cpus, gpus and tpus. Everything must be vectorized, parallel, just-in-time compiled and differentiable !
I’m building an open-source project (with a hosted option) that lets web and mobile devs add LLM-powered features with zero backend code. Current platforms like Vercel still require at least a backend serverless function even for basic LLM integrations. This handles key management, access control, usage tracking, rate limiting, message conversation state, etc so devs can focus on frontend.
I am working on a next-gen software composition analysis tool that can identify malicious open source packages through code analysis. Adopts a policy as code (CEL) approach to build security guardrails against risky OSS components using opinionated policies.
GitHub: https://github.com/safedep/vet
http://beaver.learntosolveit.com is my task management app. I am using this now, others have started using it, and continuing to build it.
I could create a portfolio page for my various projects - https://projects.learntosolveit.com/
Bedtimely[0], a personalised bedtime story generator for parents of kids aged 0-10yo. Scratching my own itch with it, especially with the participative interactive stories where the parent and child decide what happens next.
Work in progress...
I am working on Grog, the “grug-brained” alternative to Bazel. A mono-repo build tool where all you do is provide your build commands and interdependencies and the Grog will run everything in parallel while caching as much as possible.
Jumper - a tool for video editors to do visual search on their footage. ML runs locally, no clouds, uploads etc. Currently working on the DaVinci Resolve and Avid Media Composer integrations and in parallel doing a re-write of the frontend
A hackernews clone, using sqlite3, nestjs for the backend and svelte5/sveltekit/flowbyte svelte/tailwindcss for the frontend.
I must say it has been more challenging than what I though it would be, specially if you are looking to put it onto production. I'm doing it for fun though.
Nothing published yet, I'm not sure if it will ever be. What do you think ?
I’m building cronjobs in the cloud, so you dont need to worry about server downtime, silent failures or monitoring over at https://cronjs.com
Rebranding as https://cronjobs.run since ill allow more than just javascript next week!
I’m working on a service that sends weather alerts via sms. Sign up takes 3 taps from a. SMS enabled device. It’s some what useful, but I still have lots to do. Around 27 users so far.

Still working on 3D metal printer slicer CAM software, hobby UHV tolerant microscope positioning stages, and some longstanding puzzles few people would find interesting.
Also designing some odd test-platform peripherals to help validate whether a unique architecture is feasible. =3

We're off and running, making the world's best configurators for complex products. Our first clients love us. Our configurators implement some very personal ideas about front-end state management, and it's really a thrill to see it all working with real products, 3d rendering and zero latency.
I'm writing some quick and dirty software to locate Hirshmann switches, read their SNMP to determine what's connected to each port, and build a map of how the switches are connected. Hirshmann sells software to do this, but my company doesn't buy it.
It gives me my once-every-five-years reminder of why I dislike .NET.
a Finnish security engineer, a Swedish datacenter engineer, and myself built a self-hosted continuous deployment system that is built around a blue-green deployment strategy. (Inspired by AWS internal systems) we wanted a system that can integrate with any cloud service, VM provider, and/or bare metal.
We built this together at a previous organisation and moved all the internal and external services at that organisation to this system (It allowed the org to satisfy the ISO27001 requirements).
After being in operation for a couple of years, we have collected a lot of insights and feedback on what to change/improve for the open source version.
This summer I’m setting aside some time to work on making those changes for an open source version of what we call “Vanir”.
(Seems like good timing with the initiatives in EU to take back some ownership of the cloud stack).
No LLM or AI magic. Just simple state machines, extendable configuration, and a lovely GUI (web-based, no JavaScript).
The tech stack is python3, postgresql, ansible, and django.
Working on: https://www.fenra.io/
We help e-commerce sellers understand what their customers really think by analyzing feedback from various sales channels—what they like, dislike, and why
These insights can be used to improve the product, optimize listings, and refine marketing strategies

I'm working on https://fractalchat.ai It's an LLM chat interface but instead of single linear thread, in each message you can create anchors that branch off into subthreads. Useful for for digging into related subtopics/tangents without losing the parent thread's context.
Thinking about giving up on my speech accessibility project (https://BeUnderstoodApp.com) because once again I built the MVP but gaining customers is so draining and difficult for me that I consider moving away and focus on contributing to some major open source project instead
Still figuring out how to pitch it, but so far it's 'Duolingo for relationship issues'
We launched this month and are growing fast which is exciting. I'm mostly impressed by how easy React Native has gotten, as a long-time native Apple Platforms dev, given all the training LLMs have on React.
I've been learning how to make server-side mods for my Minecraft server: https://swedenmayhem.se/minecraft/
The goal is to make a Minecraft server that constantly updates itself, giving you "unlimited content", while still retaining any progress you've made so far.
We're building a repairable e-bike battery at https://gouach.com :)
An iOS app which connects parents with their children's screen time via screenshots and AI. Makes your kid's screen as visible as the living room TV. When screenshots are off, you choose what to allow; everything else is blocked. When screenshots are on, you choose what to block; everything else is allowed.
I've just released a little story game where the goal is to build trust with the main character to uncover his backstory. And now I'm trying to figure out how to get the word out, which I have 0 experience doing! https://k58.duya.io
I am building an enterprise software marketplace (backed by Microsoft). Interested devs can register here: https://www.kylantis.com/early-bird-developer to get notified when we launch. ps: we are focused on only java developers for the initial roll-out, thanks.
Suckless text editor written in Zig: https://github.com/ivanjermakov/hat
The goal is to have a full featured editor with tree-sitter and LSP support which source code you can read through in one evening.
Love how it's going so far, I'm trying to keep it both minimal and easily extendable.
A super hacky, OAI Codex/Cursor built dungeon master in your console. Started as "can I build this while riding in the car using codex?" to maybe taking it a little too far. I was happily surprised by the quality of the Wayfarer model.
I made a Chrome plugin (inspired by https://grugbrain.dev/) that can translate any big brain webpage for grugs like us.
gemini-copilot: https://github.com/binora/gemini-copilot
Just trying to make gemini-cli work with my enterprise copilot subscription.

After spending many years on the VC/startup track I found myself being pulled towards doing something more inline with my faith. As an engineer I felt like this is the best way I could contribute my skills.
A HN Reader PWA demo with my own framework rEFui
https://github.com/ClassicOldSong/refui-hackernews-demo
It started as a demo only but it looks slick so I added standalone PWA to it to be installable as a desktop app. Now browsing HN feels even better!
1) A website to measure and detect coil whine. It's been bugging me on my new Dell screen, but Dell says "it's within specs". 2) An AI-generated artwork platform with open firmware for Eink frames. 3) Server Radar: https://radar.iodev.org
Working on a platform to host and share 3D Gaussian Splatting models.
The key goal is that the creators of 3DGS models can use Blurry as a powerful tool to build the 3D experience that is performant, simple, and aesthetically pleasant for end users (viewers).
3DGS models can be shared via a link or embedded on a website, notion, etc..
