Word on the street is the CLI community was curious about Devin getting a TUI, so I built my own. @Chris_Wozniczek brought it up today on a call and got me curious about what it could look like. Obviously, I got straight to work. I think this would be clean. What do you guys think?

You asked for it, you got it. Devin TUI is officially open source😮‍💨 Runs on top of the Devin CLI you already have. Model picker with per model reasoning levels and pricing, Fusion, handoff to cloud Devin, session resume, @ file and image drops. Go break it and tell me what’s missing🫡 github.com/fenner888/devin-t…

Yes there is. CLI folks asked if there would be a TUI version, so since that community asked, i built it. But the main difference between CLI and TUI is basically how the utilize the screen and interact with the user
