What is OpenNOW?

OpenNOW is a community-built desktop client for NVIDIA GeForce NOW, built with Electron and TypeScript. It gives you a fully open-source, cross-platform alternative to the official app — with zero telemetry, full transparency, and features the official client doesn't have.

• 🔓 Fully open source — audit every line, fork it, improve it
• 🚫 No telemetry — OpenNOW collects nothing
• 🖥️ Cross-platform — Windows, macOS, Linux, and ARM64
• ⚡ Community-driven — faster fixes, transparent development
• 🎮 Anti-AFK, Stats Overlay, Adjustable Shortcuts — power-user features built in

OpenNOW is an Electron app with three processes:

Layer	Technology	Role
Main	Node.js + Electron	OAuth, CloudMatch API, WebSocket signaling, settings
Renderer	React 19 + TypeScript	UI, WebRTC streaming, input encoding, stats
Preload	Electron contextBridge	Secure IPC between main and renderer
