Umaku is a context-aware AI code review agent that understands full codebase and business logic context, detecting inconsistencies and assessing quality and risk beyond syntax-level analysis. It auto-generates and validates QA test cases from reviewed code, making it particularly effective for reviewing AI-generated code where product-intent validation matters more than style checking.

Commercial AI-native software quality and lifecycle intelligence platform. Offers a free trial / evaluation tier for engineering teams. Commercial plans feature tiered monthly and annual subscriptions based on active developer seats and monitored repositories, providing automated semantic PR reviews, AI Bugs Finder, and risk scoring. Custom Enterprise tier includes private cloud deployment, SSO, and dedicated SLAs.
