Terminal tab - Yambr

Interactive terminal running Claude Code in the side panel

What’s running

Browser (xterm.js)  ←WS→  Computer Use Server  ←WS→  Sandbox (ttyd:7681)
                          (proxy on :8081)              (tmux + bash)

ttyd — WebSocket terminal server inside the sandbox (port 7681)
tmux — persistent session; survives disconnects, scroll history preserved
Computer Use Server — transparent WebSocket proxy
xterm.js — renders in the browser

Lifecycle

Model calls sub_agent → sandbox created if it doesn’t exist.
Filter injects a preview link → side panel opens.
User sees the dashboard: running Claude Code processes, saved sessions.
Click Open terminal → ttyd starts, Claude Code launches.
tmux keeps the session alive — disconnect and reconnect freely.
Container stays up while the WebSocket is connected (keep-alive heartbeat).
Container auto-stops after CONTAINER_MAX_AGE_HOURS of idleness.

Endpoints (self-hosted)

Endpoint	Purpose
`GET /terminal/{chat_id}/status`	Is ttyd running?
`POST /terminal/{chat_id}/start-ttyd`	Lazy-start on first click
`WS /terminal/{chat_id}/ws`	Terminal WebSocket
`GET /terminal/{chat_id}/sessions`	List Claude Code JSONL sessions
`GET /terminal/{chat_id}/processes`	List running Claude Code PIDs
`POST /terminal/{chat_id}/processes/{pid}/kill`	Kill a stuck process

Dangerous mode

Toggle Skip permission prompts to run Claude Code without confirmation dialogs. Sets CLAUDE_AUTOSTARTED=1. Use only for trusted tasks.

The escape hatch

You can leave Open WebUI entirely:

Open the server URL in a new tab.
Navigate to /terminal/{chat_id}/ for a full-screen terminal.
Work with files, run code, use Claude Code — independent of the chat UI.

Sub-agents — the sub_agent tool that owns the terminal
Claude Code gateway — routing Claude Code through LiteLLM / Azure / Bedrock
