brw 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.

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. Right now that's brw, Resident, Handler, and Reminders MCP — and it grows as we open up more.

what's here
The tools we use, opened up
Everything here is something we built to get our own work done, then decided was worth sharing. Right now that's brw, Resident, Handler, and Reminders MCP. We'll keep adding to it as more of our internal tools prove useful enough to hand over.
resident
Resident
A macOS menu bar gauge for the memory your local models actually live in. Resident weights against the GPU ceiling, swap paging, per-model decode ceilings, and live tok/s — and it tells you which limit is actually binding, not just that memory is 83% full.
Resident on GitHubhandler
Handler
A macOS menu bar watchdog for the resource ceilings that take the whole machine down — open-file exhaustion, per-process attribution, time-to-exhaustion, and opt-in auto-reclaim. It shows how close you are, names the process eating the headroom, and can cut it off before launchd dies.

Reminders MCP
Your Reminders lists as twelve MCP tools in one Swift binary — due dates, alarms, repeats, priorities and notes, read and written straight through EventKit. An agent works the same list you do, on the same Mac, with no sync service in between.

More on the way
We 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
We look after people, and we build tools
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.
We start with people
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.
We build things that work
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.
We share so it gets better
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.

Use it, build on it, send the good bits back
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.
