What features does Polychromatic offer for RGB lighting on Linux?

Updated

Polychromatic is a front-end application for managing RGB lighting and other hardware features on Razer peripherals under GNU/Linux. It works as a graphical layer on top of OpenRazer, the driver project that actually talks to the hardware. If you run Linux and own a supported Razer device, Polychromatic gives you a local, no-login way to control lighting effects, configure device features, and switch settings from your desktop tray.

Core features

Controller

The Controller is the main interface for configuring hardware features and creating animated effects. This is where you set lighting behavior on your devices rather than editing config files or running commands by hand.

Tray applet

A tray applet lets you quickly change settings from your desktop's system tray. Instead of opening the full application every time, you can adjust lighting from the tray — useful when you want to switch an effect without interrupting what you're doing.

Lighting effects and device control

Polychromatic enables Razer devices to control lighting effects "and more." The lighting side is the headline capability, but the software is positioned as a general management front-end for supported hardware, not a lighting-only tool.

How it relates to OpenRazer

Polychromatic is not a driver. It is a frontend for OpenRazer, which does the low-level work of communicating with Razer devices. In practice:

  • OpenRazer provides the device support layer.
  • Polychromatic provides the graphical interface on top of it.

This means device compatibility is largely inherited from OpenRazer. Polychromatic's own site states it supports OpenRazer and that more brands are planned for the future.

Device support

According to the project, Polychromatic is compatible with OpenRazer and supports over 210 devices, including:

  • Keyboards
  • Mice
  • Mouse mats
  • Headsets

The site points to a supported devices list for the exact models. Since support flows from OpenRazer, checking that list is the reliable way to confirm whether your specific peripheral works before installing.

Local operation and licensing

Two characteristics distinguish Polychromatic from cloud-based peripheral software:

Aspect Polychromatic
Where it runs Locally on your computer
Account required No login, no cloud service
License GPLv3 (free and open source)

The project frames local operation as a deliberate design choice — "no clouds, no login" — rather than a limitation.

What to check before installing

  1. Confirm your device is supported. Cross-reference your Razer model against the supported devices list, since compatibility comes from OpenRazer.
  2. Install OpenRazer first. Polychromatic is a frontend, so the underlying driver needs to be present for it to control hardware.
  3. Decide whether you need the tray applet. If you change lighting often, the tray applet is the feature that saves the most steps; if you set effects once, the Controller alone may be enough.

One note on branding: the site states that the real snake logo is trademarked and that neither Polychromatic nor OpenRazer is affiliated with Razer.
