Devin
46 published cases mention this tool.
Devin is Cognition's asynchronous software-engineering agent, with 46 cases. It does best on narrow, well-specified tickets: Slack and Linear tasks turned into PRs, an Electron app migrated from Vue 2 to Vue 3, README rewrites. The cases also mark its boundaries: research tasks 'mostly failed,' and deep-context work can burn hours on impossible requests. One case puts the team plan at $500/month plus 10–20 minutes of review overhead per task.
