What is Devin?
Devin is an AI coding agent that acts like an autonomous software engineer on your team. It runs in the cloud or on your machine, spins up its own virtual machines, and works until a pull request is ready to merge. You can delegate big tasks, and Devin splits them across parallel cloud agents, manages them, and reports back.
To get started, you create a session and describe what you want—like fixing a bug, adding a feature, or running a security scan. Devin explores your repositories, writes code, tests it in its own browser, and records itself clicking through what it built. It can also join threads when you tag @Devin in Slack or Teams, read follow-ups, and keep working even when your laptop is closed.
Devin suits engineering teams that want to offload routine coding work, from dependency upgrades to test coverage. It supports multiple models and a Fusion mode that mixes frontier models for cost efficiency. The site mentions features like Automations, Security, Review, and Wiki, but does not state specific pricing or free plan details—check the Pricing page for that.
