Nexus vs OpenRGB: Lighting Management Compared
Published 2026-10-19, last verified 2026-10-22
OpenRGB is a free, open source app that controls RGB lighting from many brands on Windows, Linux and macOS, with no maker software needed. Nexus is one free app for lighting, cooling, monitoring and device screens on Windows, macOS and Linux.
We owe OpenRGB a lot. Adam Honse (CalcProgrammer1) started it in 2019, and its maintainers and contributors have since worked out device after device, by hand and in the open, so people can light their PCs without a separate app for every brand. Nexus bundles an OpenRGB fork for much of its third-party device coverage, so that work runs on Nexus PCs every day. Projects like this keep PC hardware open to everyone, and we are glad to build next to it. To try it on its own, download it from openrgb.org, and if it helps you, the project takes donations.
At a glance
| Nexus | OpenRGB | |
|---|---|---|
| Price | Free | Free, supported by donations |
| How lighting runs | One effect engine drives every device live | Each device's built-in modes, or Direct mode per LED |
| Layout | Every device on one canvas, LED map editor | A view per device. Visual Map plugin for one grid |
| Reactive lighting | Music, screen, media, sensors and key presses, built in | Through plugins and apps that use its SDK |
| Automation | Presets per app, brightness schedule, idle dimming, lights out on lock | Profiles on open, exit, sleep and resume. Scheduler plugin |
| Integrations | Phone remote, MCP server, Philips Hue and Govee | Network SDK, command line, E1.31 and HTTP plugins |
| Beyond lighting | Fan curves, device screens, monitoring | Lighting first, with plugins for more |
| Platforms | Windows, macOS on Apple Silicon, Linux | Windows, Linux, macOS, including 32-bit and ARM |

Device modes and one engine
OpenRGB works device by device. Each device lists the modes built into its controller, with their speed, direction and colors. These run on the device itself, so they keep going after OpenRGB closes, and Save To Device stores them where the device supports it. Direct mode sets each LED from the PC. Effects synced across devices come from the Effects plugin or from apps that use the SDK.
Nexus renders each effect on the graphics card across one shared canvas, and each device takes its colors from where it sits, so one effect flows across fans, RAM, keyboard and strips together. Devices from the bundled OpenRGB fork run in Direct mode, without their built-in modes. Turn off Nexus Control for a device and it goes back to its own lighting.
Layout
OpenRGB lets you resize ARGB zones, split them into segments and edit matrix maps, device by device. The Visual Map plugin joins devices into one grid.
Nexus puts every device on one canvas, where you move, rotate and group them and set what hangs off each ARGB port. The LED map editor places single LEDs, color tuning adjusts each device, and layout presets save the whole setup.
Reactive lighting
Nexus builds in Music Reactive (sound output or a microphone), Mirror (screen colors), Media (images, GIFs and videos), sensor effects such as CPU load, and, on Windows, Type reactive for per-key keyboards. Effect Studio builds your own effects from blocks, with no code.
In OpenRGB, the Effects plugin adds audio visualizations, Ambilight, a GIF player and shaders, Hardware Sync turns CPU and GPU readings into color, and apps such as Artemis and Aurora drive it through the SDK.
Presets, schedules and sleep
OpenRGB 1.0 profiles can load on open, exit, sleep and resume, and the Scheduler plugin switches them by time of day.
Nexus presets can follow the app in focus, the brightness schedule can follow sunrise and sunset, and lights can dim while the PC is idle. By default Nexus fades to black on lock, and on Windows also on sleep and shutdown, so RAM, which stays powered in sleep, does not keep glowing.
Where OpenRGB goes further
- Built-in device modes with Save To Device, so lighting runs with no app at all.
- A network SDK with clients in many languages, and lighting synced across several PCs.
- A command line for scripts.
- More devices you add by hand, such as DMX, LIFX, Nanoleaf and Yeelight, plus an E1.31 receiver for xLights or Vixen Lights shows.
- A lightweight app that does lighting only.
- More platforms: 32-bit Windows, Intel Macs and Linux on ARM, including the Raspberry Pi.
Where Nexus goes further
One effect across everything. One canvas, so effects line up across every device, with nothing extra to install.
Built in, not plugins. Reactive lighting, Effect Studio, layout tools and schedules are part of the app.
Native drivers. The supported list has about 2,080 device rows: over 100 on native drivers, the rest through the bundled OpenRGB fork. Native drivers cover devices such as HYTE coolers, Lian Li wireless fans and Corsair iCUE LINK, with their screens and fan control.
More than lighting. Fan curves, device screens, monitoring and a phone remote are in the same app.
