Nexus: Every light, fan and screen on your desk. One app.
Reclaim control of your PC with historical monitoring and diagnostics that respect your privacy.
Real-time CPU, GPU, and system monitoring
Every sensor, at a glance.
Real-time dashboards for CPU, GPU, memory, temperatures, fans, and more - streamed straight from your hardware, with history you can scrub back through.
- Dozens of gauge styles to build your own layout
- Desktop widgets and an in-game overlay
- History graphs for every sensor
RGB lighting control for all your devices
Lighting that reacts to you.
GPU-rendered effects flow across every LED you own - case, fans, strips, keyboard - in perfect sync. This plasma is running live in your browser, exactly as it runs in the app.
- Shader effects, rendered in real time
- One color wheel drives every device in sync
- Music-reactive and screen-ambient modes
Try it - grab the wheel or drag a slider.
Fan speeds and cooling control
Quiet when idle. Fierce under load.
Draw your own fan curves and Nexus holds every fan and pump to them, driven by any temperature sensor in your system. This is the real curve editor from the app.
- Per-fan curves with any sensor as the source
- Mixed sources and smooth ramping
- Profiles for silent, balanced, and full-tilt
Try it - drag a point; double-click the curve to add one.
Remote control from your phone, anywhere
Your PC, in your pocket.
Scan a QR code and your phone becomes a live panel for your PC - monitoring, lighting, and controls from the couch or across the internet.
- Pair in seconds with a QR code
- End-to-end encrypted, even through our relay
- Direct peer-to-peer when possible, with iOS and Android apps
Diagnostics
Catches the fault, finds the frames.
Nexus watches every drive, memory module, GPU, fan, and pump in the background, and on Windows it tracks your frame rate while you play. When something starts to fail it tells you exactly which part and exactly when; when a game runs slow, the FPS history shows you where the frames went.
- Alerts name the failing part, like a fan sitting at 0 RPM
- Temperature history shows when it started and what was running
- Continuous storage, memory, GPU, and cooling checks, no manual scan
- Per-game FPS history on Windows finds the bottleneck - ultra lightweight, nothing injected into your game
Performance
Fast and Light
Native code, hyper-optimized. No bundled browser, no background bloat, nothing between you and your hardware.
Starts instantly
Compiled ahead of time to native machine code: no runtime to warm up, nothing to load but the app itself.
No bloat
One lean binary that renders through your system's own WebView instead of shipping a whole browser. Zero external dependencies, just a few megabytes.

All downloadsWhy we built Nexus
Vendor software for PC hardware is heavy, closed, and stops at the edge of its own brand. We wanted one fast app that treats your whole system - every fan, sensor, and LED - as a single machine, no matter who made the parts.
So we built Nexus: open source, native, and designed with the same care as the hardware it drives. It runs on your machine, your data stays yours, and the community shapes where it goes next.
