Nimblegate

Nimblegate: Git push gateway that intercepts AI agent pushes to block unsafe changes and forward clean ones.

Nimblegate sits between an AI agent and a real git host to act as a git push guardrail. It checks every push against enabled rules, forwarding clean pushes in under a second and holding unsafe ones with a clear report. The gateway catches leaked keys, force-pushes, skipped or empty tests, ignored CI failures, and disabled linters. It runs self-hosted in a Docker container and is built for development teams using AI coding agents. The system supports custom regex rules and includes fifty plus built-in rules across kits like core, agent shortcuts, web app, and security strict.
