Openchamber is a really good OpenCode client.

Paseo is a layer on top of various harnesses (aka you get to use a Claude subscription), and keeps its own database of sessions, etc.

I use Openchamber (and another client in neovim), but Paseo does have one convenient advantage where you can connect to other paseo servers

Paseo doesn't offer as many features

I am not too familiar with openchamber but I think I remember passing on it because not all of its features were freely available. Another one to keep an eye on is 'happier' which is like if Paseo were designed from the beginning to be multi-domain.
