OpenClaw is probably overkill if you just want to have a nice remote UI to access claude code, do tool call approvals. There are a ton of remote cli apps and guides to setup ssh access via tailscale etc, but none that just work with a nice remote web interface.

For me personally I can't stand interacting with agents via CLI and fixed width fonts so I built a e2e encrypted remote interface that has a lot of the nice UI feature you would expect from a first class UI like Claude Vscode extension (syntax highlighting, streaming, etc). You can self host it. But it's a little no dependencies node server that you can just npm install (npm i -g yepanywhere)
