Haven't released it yet, but a little website for evaluating AI UI design. They're not actual evals, it's moreso just showing the results of different UI tasks across models, reasoning levels, skills, harnesses, etc.

I'm working on a self-tracking app and an Astro Web Starter Template! :)

The app is very customizable, local-first and is built to adapt to what you want. Goal is to combine habit tracking, health logging and journaling into one fast and easy to use interfact.

Have been working on it for almost years now and it's making great progress.

Doing closed user testing right now and will release an open beta soon: https://dailyselftrack.com/

My Astro Web Starter is built for building well-designed, performant and accessible websites. It contains everything a high-quality website needs (In my opinion). I built it so I have one good base on which to start my web projects on. Using basic HTML and CSS that can scale, without bloat.

There's a lot more on it which you can see here: https://starter.bryanhogan.com/

Description on the tin.

I found it hard to get fares and timetables for the Elizabeth Line in London between X and Y quickly hence I built this as an experiment using AI tooling.

I'm working on ownershiptrace.com. It's an entry point to SEC, FINRA and congressional trades filings. The target users are sophisticated retail investors. It's an early work in progress, and hopefully will have a substantial free tier. Let me know if you would like to provide feedback, in which case I'll give you a free premium version (limited amount ofcourse).

My web app helps people registering an imported vehicle in the UK complete the DVLA’s V55/5 registration form more efficiently.

Started a few different things:

1. A robotics information and news website. Any feedback is appreciated. https://robotica.dev/

2. Applied DBSP theory to Postgres https://github.com/getravi/pg_dbsp and DuckDB https://github.com/getravi/duckDBSP. The idea is to have incrementally maintained materialized views.

I've been looking for a site like robotica.dev that pulls together news and events from multiple sources. The funding page is awesome and unexpected, a really useful mini-crunchbase for robotics.

Thank you. Crunchbase is definitely one of the inspirations.

Whats your stack, workflow for the news site?
getravi 18 hours ago||
Currently its a astroJS site with a backend script that runs periodically and updates the website.

I'm building https://matgoat.com/en/

A way for BJJ and martial arts academy owners to manage attendance, payments, class schedules, and student progress.

I train BJJ myself and saw how much time instructors lose to admin work, so I wanted something simpler and more focused than the generic gym software out there and have been having a lot of fun building it with feedback from real academies.

Should I try BJJ?

I'm working on a own x86_64 UEFI Operating System (OS). The idea is to make an OS that looks like Windows Vista but behave like Linux, so it's a mix of Windows and Linux. I've startet three weeks ago with a custom bootloader and the legacy bios VGA textbuffer and now I'm working on a real USB-HID (USB-Human Interface Device) and have troubles with the keyboard. I also have problems with booting from real hardware. If anyone is good at low level developing the project is source available and I appreciate collaborations with other os developers. Link to Codeberg-repo: https://codeberg.org/vntx-labs/VeloOS

Hope that is no problem that I use this thread a bit for self-promotion. If so just write a reply I'll remove this comment if this is a problem

I open sourced kavla, the SQL canvas I'm working on: https://github.com/aleda145/kavla

README is very bare bones, needs a video or a picture too. The website should tell you some more things: https://kavla.dev (and now the demo does not require a login (also need to remake the demo to fit the new self hosted version))

It's still lacking an analytics agent for the local version though. I've explored using codex CLI, but it feels like its extensive system prompt cripples the agent a lot vs Kimi 2.7 that I've been using in the cloud version.

I think it would also be nice to lean into the fully local LLM setup too, especially for data that shouldn't leave the device.

It looks fun! Reminds me a bit of TLDRAW computer.

I am working on vorfract, a Voronoi voxel world which uses Voronoi cells as voxels instead of the regular cubic ones.

It's an early version so many (if not most) things that would be in a game are still missing at the moment (though planned on paper).

One interesting thing is that because the Voronoi voxels are so malleable, things like round or hollow worlds are a pretty natural outcome.

In parallel to working on it, I've been mostly using it to build and improve my own voxel castle with a pointy roof, slanted walls, custom built stairs, tables, chairs and all those nice things.

In the last update I added a CRT filter and some pixelation options as I find that appealing. As for the future (maybe as the next thing?), I guess I'd probably like to add the ability to build less blocky things like round towers (or flower vases!), but that is still very much a work in progress.

The Web version (WebGL) is completely free (and will stay that way):
