Devin 2.2 adds desktop testing, self-review autofix, and 3x faster startup

Cognition released Devin 2.2, which gives Devin full access to its own Linux desktop so it can launch and test desktop applications, not just browser-based web apps.

Devin can also plan, code, review its own output, and fix issues before opening a PR, and it now starts up 3x faster. New users get $10 in free credits, and Desktop support is enabled by default for new sessions as of February 24, 2026.
