Overalls

An AI-first developer platform that you own.

Research preview. Not for consumption. Overalls launches on 12 November 2026. Get notified.

Overalls is a self-hosted platform for development machines and the AI agents that work on them. Every machine is a persistent Firecracker microVM running NixOS, Ubuntu or Windows, and it keeps its disk, name and address when you stop, start, resize, clone or move it.

Overalls has its own agent built in: start a thread on any machine from the browser or the CLI, and it keeps working after you close your laptop, waking the machine if it was stopped. Claude Code and Codex come pre-installed too, with no API keys on the machine and every token accounted for.

Open any repository, branch or pull request in a fresh machine with one click, share it with your coworkers, and work from the browser, SSH, VS Code or the overalls CLI, or from your phone with the Mila app. Put hosts in every region your team works in.

There is no hosted version to sign up for: you install it and run it yourself.
