Devin

Devin is an autonomous AI software engineer for engineering teams. It can plan and execute software tasks, write, run, and test code, work through migrations and refactors, investigate bugs and CI failures, improve test coverage, review pull requests, and generate documentation. Devin Review and DeepWiki extend the workflow with code review and codebase understanding, while Devin for Terminal, Windsurf IDE access, Slack, Linear, and MCP integrations connect work to existing engineering systems.
