Merlin AI Code Review: Self-hosted AI code review that never leaks your code

Hey Product Hunt! 👋 I'm the maker of Merlin AI Code Review. I built this because every AI code review tool I tried required sending my source code to a third-party SaaS. For teams in fintech, healthcare, or defence — that's a dealbreaker. So I wrote Merlin in Rust — a single 12 MB binary that runs entirely inside your CI pipeline. No signup. No SaaS. No data leaving your servers. Ever. Here's what makes it different: → 6 AI backends — Claude, GPT-4o, Gemini, Bedrock, Ollama, Claude Code CLI. Swap with one config line. → 19 slash commands — /review, /security, /test, /improve, /docs, and more. → RAG pipeline — indexes your codebase so the AI actually knows your conventions. → Autonomous agent — give it a goal, it chains tools and gets it done. → Air-gap ready — Ollama + local Qdrant = 100% offline, zero external calls. It's MIT licensed, free forever, and takes under 5 minutes to set up on GitHub, GitLab (including self-hosted), Bitbucket, Azure DevOps, or Gitea. A 10-person team spends roughly $2–5/month on AI tokens. No seat fees. No vendor lock-in. I'd love your feedback — what features would you want next? Drop a comment or open an issue on GitHub. 🚀
