AI Coding Agent
Devin
An autonomous AI software engineer from Cognition that takes a task end-to-end — planning, writing code, testing, and opening a pull request with minimal supervision.
Devin, built by Cognition, is positioned as an autonomous software engineer rather than an in-editor assistant: hand it a ticket-sized task and it plans the work, writes and tests code in its own cloud environment, and comes back with a pull request rather than requiring turn-by-turn direction.
Why it stands out
- Runs the whole task loop itself — planning, coding, and testing in its own sandboxed machine, checking in only at defined points rather than every step.
- Built for ticket-style delegation, closer to assigning work to a teammate than pair-programming inline.
- Usage-based pricing (ACUs) ties cost directly to how much autonomous work it actually does.
Good for
Teams that want to hand off well-scoped, self-contained tickets for an agent to complete unsupervised and return as a reviewable PR.
