Case Study: Greptile achieves faster, cost-effective AI code review with Claude Agent SDK

Greptile builds truly agentic code review with Claude Agent SDK

Greptile builds AI agents that review code for more than 2,000 organizations, aiming to catch bugs before they reach production. Their challenge was that most AI code review tools followed rigid, predetermined checklists, whereas a skilled engineer conducts an investigation. Greptile needed an orchestration layer as intelligent as their specialized tooling to enable a truly multi-hop and autonomous review process.

By implementing the Claude Agent SDK and Claude models, Greptile empowered its agent to investigate code like a detective. The solution from Claude enabled multi-hop investigations, achieved ~90% cache hit rates for dramatic cost savings, and allowed the engineering team to focus on building specialized tools instead of infrastructure. The results include reviewing over a billion lines of code monthly and successfully catching complex bugs for major customers like NVIDIA.
