Greptile

Full-codebase-aware AI code review agent that indexes entire repositories and builds code graphs for multi-hop agentic investigation using Claude Agent SDK. v4 (March 2026) shows significant accuracy improvements. Enterprise-deployed at Brex, Substack, Scale AI, Klaviyo, and PostHog. Self-hosted with BYOLLM and air-gapped support. MONITORING: SOC 2 compliance claims compromised by Delve scandal (fabricated audit reports); needs legitimate re-certification. Benchmark claims (82% bug catch rate) conflict with independent analyses (44-45%); high false positive rate (~60% nitpick/FP). $30/dev/month.
