Javis OS
A self-hosted agentic AI operating system with a voice-controlled dashboard and a knowledge-graph second brain, letting a developer swap between Claude Code, ChatGPT/Codex, Grok Build, Antigravity CLI or API providers as its backing model.
Javis OS is a self-hosted AI agent, not a chatbot, that reads and writes files, calls tools through MCP, runs skills, schedules background jobs, and wraps all of it in a voice-controlled dashboard alongside a Second Brain that accumulates memory and a wiki over time. A single install script sets up Python, dependencies and the CLI backends already on the machine, then lets the user log into each one from the dashboard's Models page.
The backing model is interchangeable between existing CLI subscriptions such as Claude Code, ChatGPT/Codex, Grok Build and Antigravity CLI, or direct API access to OpenRouter, OpenAI, Gemini, Anthropic, Groq or Ollama Cloud. Its documentation warns that Anthropic's Claude Pro/Max terms only cover personal, ordinary use of Claude Code, that continuous background automation or several people sharing one account falls outside that scope and has led to account suspensions, and recommends running the background model through an API key instead to avoid the risk.
