Top 20 Code Review Tools for GitHub in 2026

GitHub is the default choice for most teams, which also makes it the platform with the widest selection of review and security tooling. Most tools here integrate as a GitHub App, reading pull requests and posting review comments, status checks and merge-gate decisions directly on the PR.

Because GitHub owns a large share of the market itself, with Advanced Security, Copilot code review, and Dependabot all first-party, the practical decision for a GitHub-hosted team is usually less about whether a tool can reach GitHub at all, and more about whether GitHub's own tooling already covers what you need before paying for a third-party platform on top of it.

What to look for

• Whether the tool installs as a GitHub App (repo-scoped permissions) or asks for a personal access token with broader access
• Whether it duplicates a capability GitHub Advanced Security or Copilot already covers on your current plan
• GitHub Marketplace listing and pricing, if you'd rather billing go through GitHub directly
• Rate-limit behaviour on large monorepos or high pull-request volume
