OpenCode is great and `opencode serve` in particular is very cool. Though I think the main thing is that you need to manage the OpenCode server yourself and expose it via tailscale or something like that. Our goal is to provide managed infrastructure around the coding agent harness with features like mobile, sandboxes, preview urls, etc.

Our goal is to be harness agnostic as well, so eventually we will be adding support for running OpenCode sessions in Omnara.
