For me the distinguishing feature of OpenCode is the web ui/desktop app. I’m using OpenCode because it’s the only open-source agent-harness I’ve tried that runs outside of a TUI. I like terminals but not TUIs and especially not for prose-based interactions like prompting.

But that’s a shallow moat, and the rest of the features here are not particularly interesting to me. I don’t have a use for plugins or a model-server proxy (I can connect other tools directly to the model provider).
