Looks useful, but is it open source? Would want to verify the "can't see your code/prompts" claim before pointing it at real client work — a repo link would help a lot!

Yeah, that's valid. It's not open source yet, but watch this space.

I can't even see people's email addresses when they sign up (as they just sign into their Claude Code account), but I get that you'd have to just take that on faith for now.

As it's a desktop app, someone can just point a proxy at it and watch exactly what it sends. You'll see that nothing like your conversations with Claude or even your login ever leave the app.
