Devin

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

1. Sign up at devin.ai and connect your repository
2. Assign a well-scoped task or bug in plain language
3. Let Devin plan, implement, and test in its sandbox
4. 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
