CodeRabbit is the most popular AI code review tool, providing line-by-line review on every pull request. It generates context-aware summaries, catches bugs, suggests improvements, and learns from team patterns. Integrates with GitHub, GitLab, and Azure DevOps. Widely adopted by open-source projects and engineering teams as the standard for AI-assisted code review.
Greptile is an AI-powered code review platform that understands your entire codebase to provide context-aware PR reviews. Unlike surface-level linters, Greptile analyzes how changes interact with the rest of your codebase, catching architectural issues, security vulnerabilities, and logic bugs that traditional tools miss. It integrates directly with GitHub and GitLab, and is self-hostable via Kubernetes or Docker.
