Get on the Keel beta

Keel is in a closed private beta. It mines the invariants your codebase depends on, hosts them, and enforces them as a required gate on every pull request, so AI-written changes cannot silently break what your system relies on.

Request access and we will reach out to get your repositories onboarded. Sign in with GitHub to join the waitlist.

• Invariants mined and proven from your own repositories
• A required gate on every pull request, with a concrete counterexample on failure
• No keys to manage; Keel provides model access
