I currently use Hapi (https://github.com/tiann/hapi/) for this and find it quite handy. I can easily tap into a session on my PC from my phone.

Before that I used Happy (https://happy.engineering/) which is also open source and a lot more sophisticated. It has a voice assistant that can chat with Claude Code on your behalf in the mobile app. However, it wasn't very reliable, and there are other reasons to use Hapi instead (documented in the Hapi repo).

Before that, Omnara (https://www.omnara.com/) a YC company and seemingly a proprietary Happy fork (?) but it never worked properly for me.

Long story short, there are a few of the around, and frankly I really like to use them. Unlike other commenters, I don't find that they wreck my work-life balance. Rather, I can go out and have a walk in the park, only checking in on long-running tasks every once in a while. The diff view is pretty good too. There are many tasks where I'd rather not stare at my PC all day and instead do other things, and these tools allow me to do that.
