Greptile is an AI code review platform built by Tabnam, Inc. It reviews pull requests automatically and aims to catch bugs that slip past human reviewers and static analysis tools.
The core mechanism is a graph index of the repository. Greptile maps files, functions, and dependencies, which lets it evaluate a change against the wider codebase rather than the diff alone. A swarm of parallel agents reviews each pull request and assigns a 0-5 confidence score for merge safety.
Beyond review, Greptile includes TREX, a beta agent that writes and runs tests in a sandbox for every pull request. Teams can define coding standards in plain English, and Greptile adapts to a team’s preferences by reading past PR comments.
Greptile connects to coding agents including Claude Code, Cursor, Codex, and Devin, so flagged issues can be fixed directly from the review comment. It supports both cloud and self-hosted enterprise deployment, and has raised funding led by Benchmark.

Use Cases
Automated Bug Detection
Greptile flags logical errors, security risks, and style violations before a pull request reaches production. This reduces the number of defects that depend on a reviewer catching them manually.
Standardizing Coding Practices
Teams enforce plain-English rules and style guides across every repository. This keeps output consistent regardless of an individual developer’s experience level.
Test Coverage Expansion
The TREX agent writes and runs tests for new features inside a sandbox. This helps surface edge cases that a manual test plan might miss.
Reducing Senior Reviewer Load
Automated first-pass feedback handles routine issues before a human looks at the PR. Senior engineers can then focus their time on architectural decisions instead of style nitpicks.
Onboarding New Engineers
New team members receive feedback aligned with existing team conventions from their first pull request. This shortens the time it takes to learn unwritten codebase norms.
Strengths & Weaknesses
Strengths
Evaluates changes against the full repository rather than just the diff.
Includes automated sandbox test generation through the TREX agent.
Supports self-hosted, air-gapped deployment for enterprise security needs.
Integrates directly with coding agents like Cursor and Claude Code.
Adapts to team preferences by learning from past PR comments.
Weaknesses
Only integrates with GitHub and GitLab, with no Bitbucket or Azure DevOps support.
Credit-based overage pricing at $1 per extra review can raise costs for high-volume or agentic workflows.
The free plan is capped at a single active developer, limiting team-wide trials.
The TREX test generation agent is still in beta, so results may be inconsistent.
Who Is This For?
Engineering Managers: Need a consistent way to enforce code quality and standards across distributed teams.
Individual Developers: Want automated, detailed feedback on pull requests before a human reviewer weighs in.
Enterprise Security Teams: Require self-hosted or air-gapped deployment along with SOC 2 and compliance controls.
Open Source Maintainers: Need to automate review of incoming pull requests to reduce manual triage.
