the workflow is quite different from Cursor or Copilot - Devin is an asynchronous tool. A common way to use Devin is to kick off a few sessions in the morning, while you work on other higher priority tasks. It feels a lot more like working with a colleague that you can tag in Slack or go back and forth with on PR comments
Devin has 2 hour, 6 hour and 24 hour inactivity limits before it pauses the work and temporarily deprovisions (sleep) the VM, so you have to supervise it every so often.
