Greptile

Greptile is a strong choice for engineering teams that struggle with slow code reviews or missed bugs. Its key strength is the graph index of your codebase, which lets it assess PR impact beyond the diff—catching multi-file issues that simpler linters miss. The swarm of agents means multiple checks run in parallel, speeding up the review process. CTOs at Brex and WorkOS praise its quality and lack of noise, which is a common pain point with other AI reviewers. When to pick this: If your team has complex, multi-language codebases and needs an AI reviewer that learns your conventions. The TREX test generation feature (early access) adds value for teams that want automated testing. Self-hosting and SOC 2 compliance make it suitable for regulated industries. When to pass: If you're a small team or individual developer, the $30/seat/month may be too much, especially if you exceed 50 reviews per seat. Also, if your codebase is tiny, the graph indexing might be overkill. Compared to Coderabbit, Greptile claims less noise and more context awareness. Coderabbit is cheaper but may not catch deep logical bugs. Real-world caveats: The 'learning' feature works by reading team PR comments—so it requires consistent human review initially. Language support for less common languages has lower quality. The pricing page mentions 50 reviews per seat; heavy PR teams could incur extra costs. Self-hosting may require AWS setup and using your own LLM provider.

Greptile is an AI-powered code review tool that uses a swarm of agents to review pull requests with full codebase context. Designed for engineering teams that want to accelerate code reviews and catch more bugs, Greptile indexes your repository into a graph of files, functions, and dependencies, then runs parallel agents on every PR. It learns from your team's comments over time to adapt to your coding standards. Specific features include custom rules in plain English, automatic test generation via the TREX agent (early access), and integration with coding agents like Claude Code, Cursor, and Codex. Greptile positions itself as a unified validation layer for code changes, claiming to outperform other AI reviewers like Coderabbit and Bugbot by reducing noise and providing senior-level suggestions. With over 9,000 teams using it, Greptile is built for enterprises with SOC 2 compliance, SSO, audit logs, and self-hosted deployment options. It supports major languages including Python, JavaScript, TypeScript, Go, Java, C, C++, C#, Swift, PHP, Rust, and Elixir. Pricing is $30/seat/month with 50 reviews included per seat, and additional reviews at $1 each. Free usage is available for qualified open-source projects, and discounts for pre-Series A startups. Greptile integrates with GitHub and GitLab seamlessly, and offers an API for custom use cases. For teams tired of noisy AI reviews, Greptile aims to be the first tool that doesn't annoy developers while catching multi-file logical bugs, security risks, and style violations.
