Cognition's autonomous AI software engineer: give it a GitHub issue and it plans, codes, tests, and opens a pull request in its own cloud workspace.
Devin was the first product to popularize the 'AI software engineer' concept: an agent that works asynchronously in a cloud dev environment, handling everything from environment setup to testing, then presenting a PR for review. It's built for delegation — assign work, come back to results.
From issue to tested PR with minimal supervision.
Real machines with your repo, dependencies, and tools.
Assign via Slack or GitHub; review when ready.
Teams with a backlog of well-defined tickets who want an agent that works while they sleep.
