Show HN: Themis – Self-hosted AI code reviews with your own keys and models (github.com)

Themis is a newly launched self-hosted GitHub pull request review bot that allows users to run code audits using their own subscriptions to Codex or Claude Max. The bot streamlines the review process by providing inline feedback, structured summaries, and the ability to answer questions directly within review threads. Setup is simplified through a GitHub App webhook that processes pull request events in real-time, utilizing a lightweight architecture with no external databases. This tool is significant for the AI/ML community as it empowers developers to integrate AI-driven code reviews into their workflows while maintaining control over their models and data. The ability to customize review doctrines directly from the project's repository ensures that reviews align with specific coding standards and philosophies, enhancing code quality and fostering best practices. Themis's design, leveraging Docker for deployment and requiring minimal dependencies, further boosts its accessibility for teams looking to adopt AI in their development processes.
