Devin
Also known as: Devin AI, Cognition Devin, Devin software engineer
Devin is an autonomous AI software engineer by Cognition AI, marketed as the first AI agent capable of completing end-to-end software engineering tasks independently. Devin works in a fully isolated cloud environment equipped with a shell, code editor, and browser. It can plan and execute complex, multi-step engineering tasks — from cloning a repo and writing code to deploying applications and fixing bugs — with minimal human intervention. Devin is accessible via web, Slack integration, and a VS Code extension, and cloud sessions can be managed from Devin Desktop (formerly Windsurf).

Frequently Asked Questions
Devin is described as an autonomous AI software engineer. Unlike pair programmers (Copilot, Cursor) that assist while you code, Devin works independently to complete full engineering tasks: setting up environments, writing and testing code, debugging, and deploying. It operates in a cloud sandbox with its own shell, browser, and editor, and reports back when the task is done.
Devin supports models from several providers: Anthropic (Claude), OpenAI (GPT), Google (Gemini), SpaceXAI, open-source models such as DeepSeek, Kimi, and GLM, and Cognition's own SWE models. The Free plan has limited model availability; Pro and higher unlock full model availability, and Pro includes free use of SWE-2 Free in Devin Desktop and the CLI through October 16, 2026.
Devin's plans are shared with Devin Desktop: Free ($0, light agent quota and unlimited Tab completions and inline edits), Pro ($20/month, increased quotas, full model availability, and cloud agents), Max ($200/month, significantly higher quotas), Teams ($80/month base plus $40/month per developer seat, up to 200 users), and Enterprise (custom pricing, SSO, and VPC deployment). Costs vary by model and task complexity. See https://devin.ai/pricing for details.
Devin can handle: setting up codebases from scratch, implementing features end-to-end, fixing bugs from issue descriptions, writing and running tests, deploying to cloud providers, refactoring code, updating dependencies, writing documentation, and completing tasks from GitHub issues or Jira tickets.
Devin clones your repository into a private cloud environment and has access to a terminal, code editor, and browser. It can run commands, install packages, write code, run tests, and browse documentation. You observe its progress in real time via a session dashboard and can intervene or provide feedback at any point.
Yes. Devin integrates with Slack, allowing team members to assign tasks to Devin directly from Slack messages. Devin reports progress and asks clarifying questions in the Slack thread.
Yes. Devin integrates with GitHub to work on issues and pull requests directly. It can also connect to Jira to pick up tickets and implement the requested changes. These integrations allow Devin to work asynchronously on your backlog.
Devin runs in isolated cloud environments (one per session) with no cross-session data sharing. Cognition AI uses encrypted credential storage and does not retain repository code after sessions end. Enterprise plans include additional compliance controls.
Yes. Devin has access to a cloud browser in its sandbox environment. It uses this to read documentation, search for solutions, look up API references, and navigate to any web resources needed to complete a task.
Devin performs best on self-contained tasks with clear requirements. It can struggle with deeply ambiguous tasks requiring business context, tasks requiring persistent human decisions mid-stream, proprietary internal tools it has no documentation for, and very large tasks beyond 4-8 hours of human effort. Human review of all PRs before merging is strongly recommended.
