Devin
Cognition Labs' autonomous software engineer. Handles full tasks end-to-end - reads docs, writes code, runs tests, and submits PRs in an isolated sandbox.
Devin is an autonomous AI software engineer from Cognition Labs. It operates in a full cloud development environment with a browser, terminal, and code editor. Given a task, Devin reads documentation, plans an approach, writes code across multiple files, runs tests, debugs failures, and submits pull requests - all autonomously. It handles long-running tasks (hours, not minutes) and can work in parallel on multiple tasks. It's positioned as a virtual teammate rather than a coding assistant. The pricing is per-task rather than subscription-based. It's the most ambitious autonomous coding agent currently available.
