Greptile

Greptile is an AI-driven code review tool that constructs a graph index of an entire software repository, including files, functions, dependencies, and history. It uses a swarm of parallel agents to review pull requests with full context of the codebase rather than examining a code diff in isolation. The platform includes TREX, an agent for runtime validation that writes and runs tests in a sandbox environment.

• Constructs a graph index of repositories including files, functions, and dependencies
• Uses parallel swarm agents to review pull requests and assess impact beyond the diff
• Allows teams to write custom rules in plain English to enforce coding standards
• Learns coding standards over time by reading team pull request comments
• TREX runtime validation agent that writes and runs tests for every PR in a sandbox
• One-click issue context sending to Claude Code, Cursor, Codex, or Devin
• Greptile MCP for connecting the tool to any AI agent to share comment context
• Option for self-hosted deployment in an air-gapped environment or AWS

Pros

• Understands full repository context and multi-file logic rather than just evaluating individual diffs
• Provides continuous learning capabilities that adapt to a team's specific coding patterns over time
• Supports custom rule creation using plain English instructions
• Offers flexible deployment options including self-hosting capabilities for enterprise environments
• Includes a variety of workflow integrations and plugins for coding agents and editors

Cons

• Review consumption is metered through a credit system where standard reviews and TREX reviews cost different amounts
• Additional credits beyond the monthly tier allowance cost one dollar each
• The TREX runtime validation feature is currently in beta
• Self-hosted deployment and advanced enterprise security features require contacting sales for custom pricing

Greptile fits development teams and engineering organizations looking to automate pull request reviews and catch complex bugs that require broad codebase context. It suits teams wanting to enforce custom style and security rules across multiple files automatically. It is a poor fit for organizations that do not use version-controlled repositories or teams that want entirely local, non-cloud code analysis without configuring self-hosted infrastructure or third-party LLM providers.

Greptile offers three tiers. The Starter tier is free for one active developer, includes unlimited repositories, and provides 50 credits per month. The Pro tier is recommended for teams and costs $30 per seat per month, including unlimited repositories, unlimited users, custom rules, external app connections, and 50 credits per seat per month. The Enterprise tier features custom pricing and includes options to self-hosted in your own infrastructure, SSO/SAML, GitHub Enterprise support, a dedicated Slack channel, custom invoicing, and a custom DPA. For credit usage, one standard review costs 1 credit, one TREX review costs 3 credits, and additional credits are available for $1 each. Free usage is available for qualified non-commercial open source projects with MIT or Apache licenses, and a 50% discount is available for pre-Series A startups with under $2M in revenue in the past 12 months.

Unlike conventional code review tools that evaluate pull requests strictly based on the isolated code diff, Greptile builds a graph index of the entire repository, including history and dependencies. This allows its agent swarm to trace multi-file logical bugs and catch issues that require broader context. Additionally, Greptile learns team standards automatically by reading past pull request comments and allows rules to be written in plain English.
