AI code review tools
Coding agents now write more code than any team can read. These tools read it first. All six comment on pull requests, and most also review before the PR: in your IDE, your terminal or inside the agent's own loop. Where they differ is which Git hosts they cover and how they bill: per seat, per credit or per review. 6 tools, in the order they appear in the directory. This is not a ranking.
Grouped by job: AI Coding Agents
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.
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.
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.
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.
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.

Pick it if.
- CodeRabbitYou want one reviewer on every major Git host, and before the PR too, in the CLI or inside your coding agent's loop.
- GreptileYou want reviews that read the whole codebase, not just the diff, and you'd rather pay per review than per seat.
- QodoYou're on Azure DevOps or Gerrit, or you need shared rules and cross-repo checks across many services.
