What is Devin?
Devin is the world's first fully autonomous AI software engineer, built by Cognition AI, capable of independently planning, coding, debugging, and deploying end-to-end software projects across a multi-hour session. Given a GitHub issue or a feature brief, Devin opens a browser, writes code, runs tests in a sandboxed Linux environment, reads documentation it finds online, and iterates until the task is complete — without human hand-holding at each step. It is designed not to replace engineers but to act as a junior engineer that handles well-scoped tasks autonomously, freeing senior engineers for higher-leverage work. Engineering leaders at technology companies use Devin to parallelize work across multiple concurrent tasks, effectively running several software workstreams simultaneously.
