A frontier coding agent that runs alongside Claude Code, Codex, and Cursor
Run Claude Code, Codex, Cursor, and Reason agents on the same repository without conflicts, so each tool handles what it does best.
Start an agent session from a script, CI job, or your own product, then poll or stream the result through a REST endpoint.
Give each Reason agent a name and team, and watch it work in a shared workspace alongside your human teammates.
Mention Reason in a Slack thread and get back a pull request, presentation, or answer once the task is finished.
Cognition's autonomous software engineer that ships real pull requests
Devin plans, writes code, runs tests, and opens pull requests across complex, multi-repository codebases without waiting for line-by-line approval.
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.
Mention @Devin in a thread to delegate a fix, or connect CI, PagerDuty, and issue trackers so it reacts to failures and alerts automatically.
Delegate a large task and Devin splits it across parallel cloud agents that keep working after you close your laptop, then reports back.
