nimblegate

Git push guardrails for AI coding agents.

nimblegate is a self-hosted gateway between your machine and GitHub, Gitea or GitLab. Every push from you or your agents (Claude Code, Codex, Cursor, Aider) is checked before it reaches your repo: leaked API keys, passwords, force-pushes to main and skipped tests are blocked, clean pushes go through unchanged, and every decision is recorded.

The videos here are practical walkthroughs: setting it up, closing the ways around it, and what it catches.
