When Razer Synapse Web launched with the Razer Viper V4 Pro, the community had one clear ask: bring it to the mice they already use every day.
One of the biggest requests was for the Razer DeathAdder V4 Pro. And now, that support is live.
What Is Razer Synapse Web?
Razer Synapse Web is a browser-based configuration tool that gives you quick access to essential settings on supported Razer devices. It works through supported Chromium-based browsers including Google Chrome, Microsoft Edge, and Opera, and is officially supported on Windows 11 and macOS 26. No browser extension or additional driver installation is required when your device firmware is up to date.
It gives you another convenient way to configure your gear when you want access to the settings you use most, whether you are making a quick adjustment before a game or setting up on another system.
Razer Synapse Web works alongside Razer Synapse 4, giving you more flexibility in how you configure supported devices. Razer Synapse Web focuses on essential browser-based controls, while Razer Synapse 4 provides the complete configuration experience and advanced functionality available for your device.
What Can You Customize on the Razer DeathAdder V4 Pro on Razer Synapse Web?
Razer Synapse Web gives you browser-based access to the essential Razer DeathAdder V4 Pro settings you are most likely to adjust between sessions.
With Razer Synapse Web, you can:
- Edit your onboard profile: View, edit, and save supported settings directly to your mouse’s onboard memory.
- Adjust DPI stages: Fine-tune sensitivity to match how you play.
- Configure button assignments: Customize supported mouse buttons without opening the full software suite.
- Set up on Mac: Access essential onboard profile and DPI controls through a supported browser.
- Fine-tune additional controls: Adjust mouse rotation, power saving, mouse mat calibration, and dynamic sensitivity settings.
Once saved to onboard memory, your supported settings stay with your Razer DeathAdder V4 Pro when you move between compatible systems.

To get started, make sure your Razer DeathAdder V4 Pro firmware is up to date.
- An internet connection is required to load Razer Synapse Web. Once it is loaded, you can continue using the tool offline until the browser session is closed.
