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!
Can I specify my preferences before the process starts, or does it automatically choose the best option?
Proud of you @thad_hughes_imbue for the work shipping this! I've learned so much from using Keystone as a benchmark to understand cost, performance, and failure modes of Claude Code vs. Codex vs. Opencode.
@thad_hughes_imbue it has been great to see you evolve this work on container setup over the last year from just something for us, to something anyone can use

Who hunted Keystone?
Keystone was hunted by Alexander Tibbets. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
