Stop juggling terminals. OpenACP UI is a native desktop app that puts your AI coding agents, tools, and context in one window — with a UI that actually helps you work.
Run multiple agents side by side — Claude Code, ACP agents, and any compatible backend. Each session runs independently with its own state, history, and context. Switch between them instantly.
See what tools are doing — Every tool call renders as a rich interactive card. File edits show word-level diffs with syntax highlighting. Bash output appears inline. Subagent tasks nest with step-by-step progress tracking.
Connect any MCP server — Plug in external tools via the Model Context Protocol. Jira issues, Confluence pages, and other integrations render with dedicated UIs — not raw JSON. OAuth flows handled automatically.
Built-in terminal and browser — Full PTY terminal with multiple tabs right next to your chat. Open web pages in an embedded browser without switching windows.
Project workspaces — Each project maps to a folder on disk. Sessions, history, and settings stay organized per project. Git status, staging, commits, and branches built into the sidebar.
Thinking mode — Watch Claude reason through problems in collapsible thinking blocks before it acts.
Glass UI on macOS — Native liquid glass transparency on macOS Tahoe+. Looks sharp on every other platform too.
OpenACP UI works with any CLI that speaks the Agent Client Protocol. Each agent needs to be installed and authenticated separately. See the full ACP Agent Registry for all supported agents.
| Agent | Command | Notes |
|---|---|---|
| Claude Code | npx @zed-industries/claude-code-acp |
Native support, permission modes |
| Gemini CLI | gemini --experimental-acp |
Experimental ACP flag |
| Codex CLI | codex acp |
Requires OPENAI_API_KEY |
| Goose | goose acp |

| Docker cagent | cagent acp agent.yml |
Container-based agents |
Agents are configured in agents.json at your app data directory. Each entry defines the command, args, and environment:
{
"Claude Code": {
"command": "npx",
"args": ["@zed-industries/claude-code-acp"],
"env": { "ACP_PERMISSION_MODE": "acceptEdits" }
}
}You can also add agents directly from the app sidebar.
