NIGHTS & WEEKENDS

I make little web apps
because I like making things.

My day job is robotics. This is the other thing. Most nights I end up with an idea that is too small to be a startup and too annoying to leave alone, so I build it, put a domain on it, and leave it running.

Everything below is live right now, or one command away. No signups you don't need, no ads, no analytics-industrial-complex. Some of it is polished, some of it is held together with tape, and all of it came out of an actual evening where I wanted the thing to exist.

Dub-Off

LIVE

Pick a movie scene, mute it, and re-record every line yourself. Then watch the whole mess play back and post it to the gallery.

Built because my friends and I kept quoting movies badly.

Algomon

LIVE

A browser extension that quietly records what YouTube recommends you, then shows you the pattern behind the feed.

I wanted receipts on what the algorithm thinks I am.

Marquee

LIVE

A Goodreads for concerts. Find shows near you, follow the bands and venues you care about, and keep a log of every gig you've been to.

I kept missing shows I would have loved.

FreeCAN Studio

LIVE

A CAN bus log viewer that runs entirely in a browser tab. Drop in a few hundred megabytes of vehicle traffic, decode it with a DBC, and pick apart the messages nobody ever documented. Nothing gets uploaded — it all runs on your machine.

The tools for this are expensive, Windows-only, or both.

Secret Scanner

LIVE

Point it at your GitHub account and it tells you which API keys and tokens you accidentally committed years ago.

Written the day I found one of my own keys in a public repo.

OPGuia

ON PYPI

A dead simple OPC UA browser. Point it at a PLC or let it find one on your network, then read the whole node tree, write to it, and graph any variable live.

I needed this at work and the existing options are miserable.

The tip jar

None of these make money. They cost me domains, storage, and a monthly bill I try not to look at too closely. If one of them made your day better, you're welcome to throw a couple dollars at the hosting.

And if not, honestly, just go play something. That's the point of them.
