OpenRGB
Different way of workingFreeCovers Chroma lighting only, for models on its supported list. One window for every brand in the machine, but laid out as zones and LEDs rather than previews.
Does Razer Synapse run on Linux?
Verdict: No
No. Razer makes Synapse for Windows and Mac only. Your Razer mouse and keyboard still work as a mouse and keyboard, but the macros, button mapping and Chroma lighting settings are not there.
Razer lists Synapse 4 for Windows 10, Windows 11 and recent macOS. There is no Linux version and Razer has not announced one.
Nothing stops working as hardware. Linux treats a Razer keyboard as a keyboard and a Razer mouse as a mouse the moment you plug it in, with no driver to install. If you set macros, button assignments or a DPI level and saved them into the device's own memory while you were still on Windows, those stay in the device and keep working on Linux. Anything Synapse held in the cloud or applied on the fly does not.
Lighting has a partial answer. OpenRGB controls RGB lighting on hundreds of devices including a long list of Razer keyboards, mice and mousemats, in one window that also covers your motherboard, memory and fans. Check your model on its supported devices list first, because support is marked device by device and some are listed as problematic. It is a technical grid of zones rather than Chroma's previews, and it does lighting only.
Buttons and macros have no answer for Razer. Piper, the Linux app for configuring gaming mice, covers Logitech, Roccat, SteelSeries, Etekcity and G.Skill, and Razer is not among them. Set what you need in Synapse and save it to the device before you leave Windows.
What to use instead of Razer Synapse
This doesn't have to stop you
One stubborn program doesn't have to decide the whole question. You can keep Windows on the same PC and restart into it only when you need Razer Synapse. Everything else you do can move.
