PaidFirst fully autonomous AI software engineer that takes tickets from Jira/Linear and delivers tested pull requests
What is Devin?
Devin by Cognition AI (valued at $4 billion) is the first commercially available fully autonomous AI software engineer. Unlike copilot-style tools that assist while you type, Devin takes a task description, plans the approach, writes code, runs tests, debugs failures, and opens a pull request — all without human intervention. It operates in its own sandboxed environment with a code editor, terminal, and web browser. Devin integrates with GitHub, GitLab, Linear, Jira, Slack, and 20+ other tools. Billing uses Agent Compute Units (ACUs) based on task complexity.
