AI QA engineer that reads source code to understand developer intent, then tests real user flows end-to-end — replacing manual QA.
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.
