Quick Start

Get your first AI workspace running in 60 seconds.

1. Get an invite code

arcx.run is in private beta. Get an invite code from an existing user or request one at [email protected].

2. Sign in with GitHub

Visit arcx.run, enter your invite code, and click "Sign in with GitHub". We only request read access to your profile.

3. Your workspace boots

A VS Code workspace with the arcx-agent AI launches in your browser. It takes ~10 seconds. Your workspace persists between sessions.

4. Talk to the agent

The arcx-agent panel is on the right sidebar. Type a message or use a skill:

> Help me build a REST API with Express
> /commit
> /review

What you get

VS Code in the browser with full terminal, extensions, and git
AI agent with 17 MCP servers and 21 native modules
Free AI via Ollama (Gemma 4) — no API key needed
Persistent workspace — your files, settings, and history survive restarts
32 skills — slash commands for commit, review, deploy, debug, and more

Bring your own key (optional)

For Anthropic Claude or OpenAI GPT models, add your API key in the agent settings. Your key is routed through arc-proxy, which scrubs secrets from AI responses before they're stored.
