Devin

Devin is the world's first fully autonomous AI software engineer, built by Cognition. Given a task — add Stripe payments, fix the CI pipeline, migrate the database — Devin plans the approach, writes code, tests it, debugs errors, and deploys the result without human intervention.

It operates in a sandboxed environment with its own terminal, browser, and code editor. Devin can read documentation, learn new APIs, and navigate unfamiliar codebases — setting it apart from code assistants like Copilot or Cursor.

Available through waitlist and paid team plans, Devin represents the leading edge of the AI agent revolution. Not suitable for every task, but handles well-scoped engineering work that consumes significant team time.
