RemoteXPU (GUI)
Share your GPU, CPU & NPU · Power the cluster
Turn any PC, server, or device into a node in a shared AI inference cluster. Install on multiple machines, sign in with Google, and all your compute appears as a single unified OpenAI-compatible API endpoint. Supports GPU, CPU, and NPU inference — NVIDIA, AMD, Apple Silicon, and more.

RemoteXPU (Headless)
Linux/macOS server · No GUI required
Contribute GPU or CPU compute from any headless server, VPS, or cloud instance. Runs as a lightweight background daemon — no desktop, no browser. Install with a single curl command, authenticate once with a cluster API key, and the node joins automatically.
Run: curl -fsSL https://rxpu.nixosoft.com/setup-node.sh | bash — then follow the prompts to authenticate. Requires Ollama-compatible hardware.
