open source by Revitt
Don Works is where we open up the tools we build at Revitt. We make them to do our own work properly, and when one turns out to be useful beyond our own projects, we share it here for anyone to pick up and run with. It starts with MCPlexer and brw, and it grows as we open up more.
what's here
Everything here is something we built to get our own work done, then decided was worth sharing. Right now that's MCPlexer and brw. We'll keep adding to it as more of our internal tools prove useful enough to hand over.
The gateway every Revitt agent runs through. It decides which tools an agent can reach based on the folder you're working in, keeps your secrets out of the model, asks before anything risky, and keeps a record of every call. A bit like direnv, but for AI tools.
View MCPlexerbrw drives a real, visible Chrome window so an agent can work on the actual web — signed-in tabs, real clicks and forms, and a check after every step that what it tried to do actually happened.
View brwWe build a lot of tooling at Revitt to keep our own work running. As each piece proves itself, we open it up here. Everything lives on GitHub, so you can watch the next ones land.
Don Works on GitHubwhy we do this
That's the whole idea behind Revitt, and it's the whole idea behind Don Works. We'd rather not be the kind of shop that keeps everything locked away and cut off from everyone else. Good tools get better when more people use them, poke at them, and send fixes back — so we open up the ones we think can help.
Every tool here exists because it made someone's actual work easier — ours, a client's, or both. We build for the person doing the job, not for a demo or a screenshot.
These aren't experiments we threw over the wall. They're the tools we run our own delivery on, every day, with the rough edges sanded down because we have to live with them too.
Good tools go stale when you keep them to yourself. Open them up and people find the bugs, the missing pieces, and the better ideas you'd never have had on your own. We'd rather build in the open and get there faster.
contributing
Don Works is released under the AGPL-3.0 licence. In plain terms: you can use these tools, change them, and build on them however you like, for free. The one thing we ask is that if you improve them, you share those improvements back — even if you're running a changed version as a service. That way everyone's copy keeps getting better instead of quietly forking off into a dozen private versions. If that doesn't fit how your business works, talk to us at Revitt about a commercial licence — that's one of the ways the open work and the paid work look after each other.
