Overview
CodeRabbit and Greptile both use AI for code review but approach it differently. CodeRabbit integrates directly with GitHub and GitLab to provide AI-generated review comments on pull requests. Greptile indexes your entire codebase to provide AI-powered understanding, making its review comments more context-aware about how changes fit into the broader codebase.
Choosing Between Them
CodeRabbit is the more established and easier-to-setup option. Install the GitHub app and you get AI reviews on your next PR. Greptile requires more integration work but can provide deeper insights because it understands your full codebase context, not just the PR diff.
