Codegen

Codegen is a managed platform for running autonomous coding agents at scale — tag it in an issue/chat/API, it gathers repo context, writes code + tests + docs, and opens a ready-to-review PR. Ships with repo rules, sandboxed execution, granular agent permissions, snapshot/image caching, and first-class GitHub/Slack/Linear/MCP integrations. Routes between Claude, Gemini, customer-brought models, and future frontier models. Used by 1000+ teams including Notion, Linear, and Origin Financial; has produced 230k+ PRs with a 52% merge rate. Acquired by ClickUp in December 2025.
