Do I need a cloud account to use Zeus?

No. Zeus runs entirely locally with no cloud account or telemetry required. Your agents, skills, memory, and workspaces are plain human-editable files stored in ~/.zeus on your own disk, with the option to bring your own AI model or install a fully local model via the built-in Ollama integration.

Can I use Zeus on my phone?

Yes. The UI is an installable PWA (progressive web app) with a mobile-first layout. Running zeus start --tailscale serves the app on your private Tailscale network so you can install and use Zeus from your phone anywhere, logged into the same tailnet.

What models does Zeus support?

Zeus works with cloud providers (Anthropic, OpenAI, Groq, Google Gemini, OpenRouter, AWS Bedrock) by pasting an API key, or fully local models via the built-in BYO Model app, which lets you browse and pull any model from the Ollama library and run them entirely on-device inside ~/.zeus.

Zeus: open-source local AI agent with web and mobile UI

Send on LINE

Key takeaway

Zeus is a new open-source application that runs AI agents locally on your computer with a web and mobile UI, letting agents interact with files, shell commands, and browsers without cloud vendor lock-in.
All data stays on your machine in editable files, and you can bring your own AI model—cloud or fully local—making it useful for developers and non-technical users who want private, self-contained agent automation.

3 Key Points

What happened
Zeus is an open-source application that lets users run AI agents locally on their computer via a web UI and mobile app. Agents can read and write files, run shell commands, control a browser, search the web, manage tasks, and orchestrate sub-agents — all without sending data to the cloud.
Why it matters
Users retain full control over their data (stored in plain files on disk) and can choose any AI model — cloud-based (Anthropic, OpenAI, Groq, Google Gemini, OpenRouter, AWS Bedrock) or fully local via the built-in Ollama integration. The application handles the complexity of agent orchestration, memory management, and timeout handling in one place.
What to watch
Zeus is open source and early-stage. Installation requires Python 3.11+ and runs on macOS or Linux/WSL. The web UI launches at http://127.0.0.1:8756; users can also serve it on a private Tailscale network to control agents from a phone anywhere.
