Devin

Devin is the autonomous AI software engineer from Cognition Labs. Hand it a Jira/Linear ticket or GitHub issue; Devin runs in its own VM with a browser, terminal, and editor, plans the change, writes code, runs tests, debugs, and opens a PR. You review like any other PR. Pricing: Core at $20/month (limited ACUs), Teams at $500/month. In real-world testing, Devin completes about 65% of well-scoped tickets unsupervised — comparable to a focused junior engineer. Fails more often on cross-file refactors, ambiguous requirements, or messy legacy code.
