opencode behind a nginx proxy with a standard user/password is sufficiently powerful. You can also upgrade to https://docs.linuxserver.io/images/docker-code-server/ and run any vscode plugins; opencode's plugin is pretty rudimentry but cline has been making a lot of strides.
You can run your local LLM and just connect the docker containers. I'm paranoid of being disconnected from the LLM, so I never run any of this on the same machine, so orchestrating a docker-compose file that provides the necessary services is important.
I'm still trying to find a good remote file system to loop into the setup for improved switching between cli and these web containers.
