Octopus Code Review is an open-source AI code review tool built on RAG (Retrieval-Augmented Generation) architecture with Qdrant vector search. Unlike traditional static analysis tools, Octopus understands your entire codebase context and delivers intelligent, project-specific feedback on pull requests through native GitHub integration. It identifies bugs, security issues, and architectural concerns while respecting your team's coding standards and patterns. Fully self-hostable, Octopus ensures your source code stays on your infrastructure. No vendor lock-in, no data leaving your environment. Designed for teams that want automated code review without compromising on code privacy or review quality.
