What is Devin?
Devin, from Cognition, is an agentic coding tool that takes a task and works through it autonomously: reading the codebase, writing and running code, debugging, and opening pull requests. It runs in its own cloud environment and is aimed at offloading well-scoped engineering tickets rather than pair-programming line by line.
Key features
- Autonomous, multi-step task execution in its own dev environment
- Reads and navigates existing codebases
- Runs code, tests, and debugs its own output
- Opens pull requests and responds to review feedback
- Slack and IDE integrations for handing off tasks
How to get started
- Sign up at devin.ai and connect your repository
- Assign a well-scoped task or bug in plain language
- Let Devin plan, implement, and test in its sandbox
- Review the resulting pull request before merging
Use cases
- Knocking out well-defined engineering tickets
- Migrations and repetitive refactors
- Fixing bugs with clear reproduction steps
- Prototyping features from a spec
