About

Open is an open source code review agent that automates the code review process. It reviews changes the way a human reviewer would — reading the diff in the context of the codebase and leaving actionable comments — so teams can merge faster without letting review quality slip. Being open source, it can be self-hosted, inspected, and extended to fit a team's own review standards.

Key Features

**Automated code review: ** incoming changes are analyzed and commented on automatically, on every update.
**Context-aware feedback: ** reviews consider the surrounding codebase rather than judging lines in isolation.
**Actionable comments: ** findings come as concrete review comments developers can act on immediately.
**Open source: ** the full agent is public — audit how it works, self-host it, and adapt it to house rules.
**Reviewer workload relief: ** human reviewers focus on architecture and judgment while routine findings are automated.
