Bito
Bito's AI Code Review Agent: codebase-aware reviews on GitHub, GitLab and Bitbucket pull requests, in VS Code, JetBrains, Cursor and Windsurf, and from the CLI, with one-click fixes, custom guidelines and review analytics. Bito-hosted or self-hosted.
CodeRabbit
AI code review for pull requests on GitHub, GitLab, Azure DevOps and Bitbucket, and before the PR in the CLI, your IDE and coding-agent loops: plain-language walkthroughs, one-click fixes, pre-merge checks, slop detection for low-quality AI PRs, and reviews that learn from your team's feedback. Free on public repos.
farol (PR risk map)
Free, open-source (MIT) CLI and GitHub Action from Winnin that runs after your AI code review and tells the approver how risky a pull request is: a 0-100 risk score and verdict from reach, diff coverage, security findings, contract breaks and dependency changes, plus the pages, APIs and jobs the change reaches. Static analysis only, for TypeScript/React, Go and Python; never blocks a merge.
Graphite
Code review platform for GitHub: stacked pull requests from a CLI, VS Code extension or MCP, a PR inbox, a merge queue, and AI reviews with custom rules, filters and one-click fixes. Free Hobby plan for personal repos.
Greptile
AI code reviewer that indexes your repo as a graph of files, functions and dependencies, then runs a swarm of agents over each pull request to catch bugs beyond the diff, and learns your standards from teammates' review comments. Works with GitHub, GitLab and Bitbucket; Enterprise adds self-hosting, Gitea and Perforce.
Qodo
Multi-agent AI code review for pull requests on GitHub, GitLab, Bitbucket, Azure DevOps and Gerrit, with a rules system built from your PR history, cross-repo review that catches breaking changes downstream, and a CLI toolbox that gives Codex, Claude and Kiro a review step inside the agent loop.
Sourcery
AI code review for GitHub and GitLab, including self-managed GitLab: reviews every pull request with summaries, diagrams and one-click fixes, follows your custom review rules, runs security checks, and can auto-approve low-risk PRs. Free on public repos.
Whiteboard
Open-source canvas for thoughtful software design: review interactive visualizations, diffs and agent trajectories in one interface on macOS, Windows and Linux; by /dev/fast (YC W26).
