Keystone self-configures a working devcontainer for any git repo, all on its own. Give it a repo. Get back a Dockerfile, devcontainer.json, and a passing test runner. It runs a coding agent inside a sandboxed Modal environment so your machine is never touched. It’s open-source, works with Claude Code and Codex, and the dev containers it produces work in VS Code and GitHub Codespaces. pip install imbue-keystone
At Imbue, we think code repos should self-describe their ideal environment. That’s why we built Keystone, to help agents automatically configure their own perfect Docker playground.
Excited to hear your feedback!
