Coldtea is an agentic development environment that covers the software lifecycle beyond coding, including QA testing, production monitoring, bug detection, and automated fixes. It lets teams run multiple coding agents such as Claude Code, Codex, and Gemini CLI together in a unified terminal, where agents can plan, build, review, and improve work collaboratively. QA agents turn plain-English descriptions into self-healing tests that run against every pull request preview, while monitoring agents watch production logs, customer feedback, and user sessions to open pull requests for detected issues. Coldtea also syncs with engineering boards to assign tasks to background cloud agents and surfaces technical debt introduced by AI-generated code.
