Collaborator
A desktop workspace for building with agents.
Collaborator is a desktop app for working with coding agents. Terminals, notes, code, and images sit together on an infinite canvas, and everything operates on local files. The terminals are built for running agents, so you can keep several going at once and glance across them the way you’d glance across a desk.
On March 13, 2026, I posted a thirteen-second video of it with the caption “testing something.” It went around: a few hundred thousand views in a couple of days, and a reply thread full of people asking where to download it. Two days later the app was on GitHub as collab-public, where it has since picked up nearly three thousand stars, a run of releases through v0.8, and Windows and Linux builds alongside the Mac one.
It’s my first attempt at a workspace designed around agents rather than around a single editor. Using it every day made the real problem clear: the agents need a machine more than they need a canvas. Every long-running session is tied to your laptop being open and online. That realization became Cube Computer, which moves the machine to the cloud and keeps the multi-session workspace. Collaborator’s canvas, terminal daemon, and file navigator all live on in Cube in evolved form.
