Co-Review

Co-Review is an open-source desktop review app, built on Eclipse Theia, that lets you read a whole repository, your agent's diff or a pull request together with the coding agent, using inline comment threads the agent answers.

Why it matters

Developers who build mostly with coding agents can lose track of how their own codebase works. Co-Review gives them a structured way to review the repo with the agent that wrote it and ask why things are built the way they are.

Highlights

• Whole-repository audits: the agent writes a guide to the code's map, vocabulary, flows and weak spots, with proposed findings by area you accept or dismiss, and coverage tracks what you've read.
• Inline threads on a line, symbol, file or folder; comments are anchored with Tree-sitter so they follow code through edits.
• Commands for Claude Code (/co-review:audit, :review, :pr, :design) and packages for Pi and Oh My Pi; other agents connect over MCP.
• Can post a pull request review with line comments to GitHub when you choose to.
• No telemetry or account; reviews are stored locally in ~/.co-review.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Worth knowing: Builds aren't code-signed yet, so macOS and Windows show security warnings on install. Your code goes to whichever agent you connect.
