Vis

An alternative web UI for OpenCode, designed for daily use. It connects to a running OpenCode instance and provides a browser-based, window-style interface for managing sessions, viewing tool output, and interacting with AI agents in real time.

Features

• Review-first floating windows that keep tool output and agent reasoning in context
• Session management with multi-project and worktree support
• Syntax-highlighted code and diff viewers built for fast, confident review
• Permission and question prompts for interactive agent workflows
• Embedded terminal powered by xterm.js

How to Use

Local

Serve the UI locally and then open http://localhost:3000 in your browser.

Start the UI server:

pnpm install
pnpm build
node server.js

Start the OpenCode API server:

opencode serve --cors http://localhost:3000

Or add this to your .config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "server": {
    "cors": ["http://localhost:3000"]
  }
}

and then:

opencode serve
