To configure your Razer mouse, you need Razer Synapse, the official software for managing Razer devices.

Razer Synapse 4 is the current primary software, offering faster performance, optimized memory usage, and advanced features like customizable button mapping, DPI stages, sensor calibration, and Hypershift for dual button sets. It supports cloud profile syncing and automatic profile switching based on active apps or games.

You can download Razer Synapse 4 directly from the official Razer website:
👉 https://www.razer.com/synapse-4

For Mac users, Razer Synapse for Mac is available for Apple Silicon Macs running macOS 15 Sequoia or later.

💡 Note: Synapse 4 replaces Synapse 3. Installing it will uninstall Synapse 3. Avoid installing extra apps (like Razer Chroma) during setup if you only want the core software.

You can use Synapse without logging in, but signing in with a Razer ID enables cloud sync and full customization.

Try Synapse 4. It’s supposed to be much faster and lighter, and I’ve been using it since the Beta. Answer from DensityInfinite on reddit.com

r/razer on Reddit: New Mouse. Do I need Razer software?
October 24, 2024 -

Basically title.

I just picked up a new Razer Viper Ultimate wireless and I was wondering if I need Razer’s software to make use of it.

I used to use Synapse for a BlackWidow X keyboard years ago before I was given a new brand but I really disliked their software because of how many problems it gave me on my computer back then (multiple restarts, high usage, didn’t connect). So I would like to stray away from using it but maybe it’s better now and hopefully more Razer experienced people here can let me know.

Also if anyone else has a Razer Viper Ultimate, is there anything you could let me know that I otherwise wouldn’t?

r/MouseReview on Reddit: Do Razer Mice require software to work?
August 23, 2022 -

So early on in my search for a mouse I was really interested in Razer but then I read a few accounts of their software slowing down peoples computers and that deterred me from exploring them further. I also heard negative things about logitech software but then read about workarounds and that you don't have to keep their software installed and can rely on onboard memory without softare.

Does Razer require that you keep their software on your pc to use their mouse? Do you have to run it in the background or can you use their mice without ever touching their software?

r/razer on Reddit: Using Razer mouse without Synapse
September 17, 2024 -

Hi! I’m looking for a piece of advice. I need a new mouse and this time I really want a wireless one. Sadly I cannot really find anything that checks all the boxes. I would love the Logitech MX Master 3 but the polling rate is sadly too low… that’s why I decided to get the Razer Basilisk v3 Hyperspeed. But my question is: can I use it without synapse? I don’t really want this software. I dont care about lights but I care about buttons programming. So first question is:

  1. If I shut down the software after programming the buttons, will they still work? I assume I cannot fully uninstall it?

  2. I switch constantly between my working laptop and a gaming one, will the buttons stay programmed on each laptop or would I have to program them every time I switch? (As far as I know there is no onboard memory for the mouse)

i don't have a basilisk but i have a naga. i don't know if the concept is the same but i suppose it is you have to install synapse to program your mouse. Since the basilisk doesn't have a button for switching profiles (Naga has on on the bottom) you have to assign this command to one of the buttons the mouse has, IF you plan to have different profiles (for games, softwares, etc). This is only if Basilisk can store more than 1 profile (Naga can have 5), so check for this. Otherwise the settings will be remembered but you will have just one profile and if you want to have more than 1 you will need the software always running in the background Once the mouse has been programmed the way you want, you can go to windows settings and disabile Synapse to be launched at start (but keep it installed in case you want to change something)

November 26, 2017 - Mouse has pretty high priority. Similiar to CTRL+ALT+DLT More replies More replies ... Never need a reboot in Windows 10. Are you still on 7? ... I have the Razer software for my Orbweaver (keypad). Ive found you dont actually need to restart the PC, you can just restart the app and it still works.
