Just remember, OpenCode is sending telemetry to their own servers, even when you're using your own locally hosted models. There are no environment variables, flags, or other configuration options to disable this behavior.¹

At least you can easily turn off telemetry in Claude Code - just set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC to 1.

You can use Claude Code with llama.cpp and vLLM, too right out of the box with no additional software necessary, just point ANTHROPIC_BASE_URL at your inference server of choice, with any value in ANTHROPIC_API_KEY.

Some people think that Anthropic could disable this at any time, but that's not really true - you can disable automatic updates and back up and reuse native Claude Code binaries, ensuring Anthropic cannot change your existing local Claude Code binary's behavior.

With that said, I like the idea of an open source TUI agent that won't spy on me without my consent and no way to disable it much better than a closed source TUI agent that I can effectively neuter telemetry on, but sadly, OpenCode is not the former. It's just another piece of VC-funded spyware that's destined for enshittification.

Are you sure that endpoint is sending all traffic to opencode? I'm not familiar with Hono but it looks like a catch all route if none of the above match and is used to serve the front-end web interface?

That linked code is not used by the opencode agent instance though right? Looks related to their web server?

They don't. That is just the route for their WebUI, which is completely optional.

I've point thought about making things that just send garbage to any data collecting service.

You'd be surprised how useless datasets become with like 10% garbage data when you don't know which data is garbage

Does opencode still work if you blackhole the telemetry?

this is a big red flag
