GO Chat UI

The missing chat UI for OpenCode Go. Beautiful, simple, local and open source. Unofficial — bring your own API key. The missing chat UI for OpenCode Go. Beautiful, simple, local and open source.

Click the toolbar icon on any page and start typing. Every model on your plan is already in the picker, and nothing is saved anywhere but your own browser.

🔒 LOCAL FIRST

Your API key and every conversation you have are stored in your browser's own local storage, and nowhere else. We run no server, so there is nothing for us to read, sell, or lose. No analytics, no telemetry, no tracking.

The extension sends your messages to one place: OpenCode's API, authenticated with your own key, so the model can answer them.

And none of this has to be taken on trust: GO Chat UI is open source under the Apache 2.0 licence. Read every line at github.com/bambamhq/gochatUI.

⚡ FEATURES

🪟 A real window — drag it, resize it from any edge or corner, or shrink it to a floating chip. It reopens exactly where you left it. 👆 Out of your way — click the page behind it and it tucks itself back into the chip. Switch that off if you would rather it stayed put. ⚡ Streaming replies — answers appear as they are written. 🤖 Every model on your plan — pulled live from your subscription, so new models appear the day they launch. Searchable when the list gets long. 🌗 Light and dark — follows your system, or pick one and stick with it. 🤔 Quiet by default — reasoning models show a shimmering "Thinking" indicator instead of pages of chain-of-thought. Turn the full transcript on if you want to read it. 💾 Chat history — your last 50 conversations, each showing the tokens it used. 📝 Markdown and code — headings, lists, tables, links, and syntax-styled code blocks.

🔑 REQUIREMENTS

Your own OpenCode Go API key from opencode.ai/go. This extension does not include a subscription and does not sell one.
