Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Nimblegate is a self-hosted Git push gateway that sits between AI coding agents (Claude Code, Codex) and your real Git host, intercepting pushes to enforce safety rules like leaked keys, force-pushes, and skipped tests. It provides over 50 configurable rules grouped into kits, with a dashboard, auto-PR feedback, and MCP integration for agents. The project addresses a real emerging gap as AI agents become more autonomous in development workflows.

Target audience: backend devs, devops, security engineers, AI-assisted development teams
