Devin

Cognition's autonomous software engineer that ships real pull requests

End-to-end autonomous coding

Devin plans, writes code, runs tests, and opens pull requests across complex, multi-repository codebases without waiting for line-by-line approval.

Its own virtual machines

Devin provisions Windows, Mac, and Linux VMs, builds and runs the project, and tests in a real browser - even recording itself using the feature it built.

Slack, Teams, and alert integration

Mention @Devin in a thread to delegate a fix, or connect CI, PagerDuty, and issue trackers so it reacts to failures and alerts automatically.

Parallel cloud agents

Delegate a large task and Devin splits it across parallel cloud agents that keep working after you close your laptop, then reports back.

Strengths & Pros

+Handles ticket-level autonomous work rather than only suggesting code completions
+Tests in its own browser and VMs, which catches issues that pure code generation misses
+Deep workflow integration with Slack, Teams, CI, and alerting tools
+Keeps working in parallel cloud agents even when your machine is off
