Devin
AI software engineer that plans, writes, tests and deploys code autonomously — the first fully autonomous AI coder.
Devin by Cognition is an autonomous AI software engineer that can complete entire software engineering tasks end-to-end. Given a high-level goal, Devin plans the approach, writes code, runs tests, fixes bugs, and deploys results — all within its own sandboxed development environment. It can work with any codebase, use common developer tools, and report progress with detailed reasoning. Devin represents a new category of AI agents that function as full team members, currently available through Cognition's platform for enterprise and individual developers.
Key Features
- Autonomous end-to-end coding tasks
- Planning and reasoning with step-by-step output
