Code Climate

Retired

Pioneering automated code review platform founded in 2011 that helped define the category. Now focused on Software Engineering Intelligence (SEI) and Velocity — providing engineering leaders with metrics on delivery performance, cycle time, and team productivity. The original Code Climate Quality product was spun out as Qlty Software in 2024. Legacy code review bot activity reflects the pre-spinout era.

Qodo

Retired

Code integrity platform (formerly CodiumAI) that uniquely integrates test generation with code review. Identifies areas lacking test coverage and auto-generates test cases to catch potential bugs. Bridges the gap between "reviewed code" and "tested code" — treating testing as an integral part of the review process rather than a separate concern.

Greptile

Codebase-aware AI code review that indexes your entire repository to understand architecture, dependencies, and design patterns.
