GitHub - OpenCloudGaming/OpenNOW: Custom GeForce Now Client Named OpenNOW

An open-source desktop client for GeForce NOW.

Browse the catalog, tune your stream, and launch sessions from a community-built app.

Warning

OpenNOW is under active development. Expect occasional bugs, rough edges, and platform-specific issues while the client matures.

Important

OpenNOW is an independent community project and is not affiliated with, endorsed by, or sponsored by NVIDIA. NVIDIA and GeForce NOW are trademarks of NVIDIA Corporation. You must use your own GeForce NOW account.

Overview

OpenNOW is a community-built Electron app for playing GeForce NOW from an open-source desktop client. The active implementation lives in opennow-stable/ and uses Electron, React, and TypeScript across the main, preload, and renderer processes.

The project aims to give players a transparent, customizable alternative to the official client without hiding the technical parts from contributors.

Highlights

Open-source desktop client for Windows, macOS, and Linux
Catalog and public game browsing with search and library-aware session handling
Stream controls for codec, resolution, FPS, aspect ratio, region, and quality preferences
In-stream diagnostics overlay with latency, packet loss, decode, and render stats
Built-in screenshots, recording, microphone controls, and controller-friendly navigation
Local settings storage and zero-telemetry project direction

Settings

Nix

You'll need to add this repo into your flake.nix:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    
    opennow.url = "github:OpenCloudGaming/OpenNOW";
    opennow.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = {
    self,
    nixpkgs,
    opennow,
    ... }@inputs: {
  };
}

Then add the package to your configuration:

# Home-manager
{
  pkgs,
  inputs,
  ...
}: {
  home.packages = with pkgs; [
    inputs.opennow.packages.${pkgs.system}.default
  ];
}

# Nix configuration
{
  pkgs,
  inputs,
  ...
}: {
  environment.systemPackages = with pkgs; [
    inputs.opennow.packages.${pkgs.system}.default
  ];
}

Documentation

Architecture At A Glance

OpenNOW is split into three Electron layers:

Layer	Tech	Responsibility
Main	Electron + Node.js	OAuth, CloudMatch/session orchestration, signaling, caching, local file handling
Preload	Electron `contextBridge`	Safe IPC bridge between the app shell and UI
Renderer	React + TypeScript	Login flow, browsing, settings, WebRTC playback, diagnostics, controls

The code lives under opennow-stable/src/, with shared TypeScript types and IPC contracts in opennow-stable/src/shared/.

FAQ

Is this the official GeForce NOW client?

No. OpenNOW is a third-party, community-maintained client.

Does OpenNOW collect telemetry?

The current project direction is zero telemetry. Settings and media stay on the local machine, and authentication is performed against NVIDIA services.

What happened to the earlier Tauri/Rust version?

The active client in this repository is the Electron-based app in opennow-stable/.
