offstage gives Claude Code, Codex and opencode a second, logged-in macOS account to work in. Simulators, Xcode UI tests and the app your agent just built open on that account's desktop, so your screen, keyboard and mouse stay yours. Free and open source: https://github.com/viraatdas/offstage
Hi Product Hunt! I'm Viraat, and I built offstage.
Every time my coding agent tested the Mac app it had just built, it took over my screen: windows jumping to the front, the mouse moving on its own, a Simulator booting in the middle of whatever I was doing.
offstage gives the agent its own macOS account instead. It's a second user, logged in behind yours with fast user switching, so it has its own window server, framebuffer, and keyboard and mouse stream. A small Swift daemon inside that account launches apps, takes screenshots and posts clicks through CGEvent's per-session tap, so input can't land on your screen. It refuses to send input at all if its session is ever the one on the console.
It also routes everything else your agent runs. Headless commands run in place, headed browsers go to a Linux container with a virtual display, macOS GUI work goes to the second account, and installers are refused outright. It isn't a VM: the helper account takes about 3 GB and there's nothing to boot.
Try it: paste this into your coding agent
Codex and opencode work too; the README has their configs. It's free and MIT licensed, for Macs on Apple Silicon. I'd love to hear what you'd point your agent at first, and where it breaks.
Giving the agent its own desktop makes a lot of sense. The bit about refusing input if its account becomes the active session is a thoughtful touch. Congrats on getting this out, Viraat!
