devs-webadmin 3.2.4

Web admin UI for managing devcontainers on a server

devs-webadmin - Web Admin UI

A web-based admin interface for managing devcontainers on a server. Provides the same core functionality as the devs CLI but accessible from a browser -- useful for headless servers, remote machines, or when you want a visual overview of running containers.

Features

• Container Management: Start, stop, and clean up devcontainers from a web UI
• Repository-Based: Enter any GitHub org/repo to start containers (uses RepoCache, no local checkout needed)
• All Containers View: See all devs-managed containers across all projects at a glance
• VS Code Tunnels: Start, stop, and authenticate tunnels directly from the browser
• Tunnel Auth via Device Flow: GitHub device code flow for tunnel authentication without needing a terminal

Installation

# From the monorepo root
pip install -e packages/webadmin/

# Or when published
pip install devs-webadmin

Quick Start

# Start the web admin server
devs-webadmin serve

# Open http://localhost:8080 in your browser

Usage

Starting the Server

# Default: 0.0.0.0:8080
devs-webadmin serve

# Custom host/port
devs-webadmin serve --host 127.0.0.1 --port 3000

# Development mode with auto-reload
devs-webadmin serve --reload

Web UI

The UI has two main sections:

Start Container Form -- Enter a GitHub repository (e.g. ideonate/devs) and a dev name (e.g. sally), then click Start. The repo is cloned/updated via the shared repo cache at ~/.devs/repocache/.

Container List -- Shows all devs-managed containers with:

• Status (running/exited) with color indicators
• Project name, mode (copy/live), creation time
• Stop (preserves container state) and Clean (removes container + workspace) buttons
• Tunnel controls for running containers

Tunnel Controls

Each running container shows a tunnel panel:

• Start tunnel -- Launches a VS Code tunnel in the container. Once running, shows an "Open in browser" link to vscode.dev.
• Kill tunnel -- Stops a running tunnel.
• Auth -- Opens a modal with the GitHub device flow. A device code is displayed along with a link to github.com/login/device. Complete the login in your browser and the modal updates automatically when authentication succeeds. Auth persists across container stop/restart cycles.

Configuration

Environment Variables

Variable	Default	Description
WEBADMIN_HOST	0.0.0.0	Server bind address
WEBADMIN_PORT	8080	Server port
DEVS_WORKSPACES_DIR	~/.devs/workspaces	Workspace directory
DEVS_REPO_CACHE_DIR	~/.devs/repocache	Repository cache directory
DEVS_CLAUDE_CONFIG_DIR	~/.devs/claudeconfig	Claude config directory
DEVS_CODEX_CONFIG_DIR	~/.devs/codexconfig	Codex config directory
GH_TOKEN / GITHUB_TOKEN	(none)	GitHub token for private repos

Shared Directories

The webadmin shares the same directories as the CLI and webhook:

• ~/.devs/repocache/ -- Cached repository clones
• ~/.devs/workspaces/ -- Workspace copies for containers
• ~/.devs/claudeconfig/ -- Claude authentication

Architecture

Backend

• FastAPI + Uvicorn (same stack as the webhook package)
• Uses devs-common for all container/workspace/repo operations
• Synchronous common library calls wrapped with asyncio.to_thread
• Stop/clean operations work by Docker container name (no repo cloning needed)

Frontend

• Vue 3 loaded from CDN (no build step, no npm required)
• Single index.html served as a static file from the Python package
• Self-contained -- ships inside the pip package with no external build process

API Endpoints
