About

Hey HN, we built Octopus an open-source, self-hostable AI code reviewer for GitHub and Bitbucket. It uses RAG with vector search (Qdrant) to understand your full codebase, not just the diff, and posts inline findings on PRs with severity ratings. Works with Claude and OpenAI, and you can bring your own API keys.

AI Score Reasoning

Octopus targets a high-growth market in AI-assisted development with a compelling open-source and self-hostable value proposition that differentiates it from SaaS-only incumbents. However, the project is in its earliest stages with minimal traction signals and faces significant competitive pressure from well-funded startups and native platform features.
