Razer Synapse Web can adjust selected devices in a browser without installing the full desktop app. It is useful for quick customization, but compatibility and available controls are limited.
Choose your operating system and goal. Add a device name or RZ model number for an extra compatibility reminder.
The result includes platform requirements, the reason for the recommendation, and a verified Razer source link when one is available.
| Installation | Runs in a compatible browser |
|---|---|
| Device support | Limited to products on Razer's Synapse Web list |
| Firmware | Razer recommends updating device firmware first |
| Typical controls | Selected settings, on-board profiles and Chroma quick effects |
| Full replacement | No; available controls are narrower than the desktop app |
The web experience is suited to quick changes on a supported device, especially when you do not want to install the full app or are using a computer where installation is unavailable.
Razer highlights fine-tuning selected settings, switching on-board profiles and using Chroma RGB quick effects. The exact controls depend on the device.
Update the device firmware, connect the hardware directly when possible, open Razer's web service in a compatible browser and grant only the device permission needed for the session.
If the browser cannot see the device, confirm that the model appears on article 20604 and close other software that may already control the hardware.
The browser tool does not promise every module, cloud function, macro workflow or device integration found in Synapse 4. Use it for the supported actions it exposes.
Chromebook, Linux and Intel Mac users may find the web option useful only when their exact device is on the web list. The existence of the service does not create universal platform support.
Start with a supported keyboard that stores profiles on-board. Update its firmware, close desktop control software, connect it directly and open the official web service. If the browser exposes the expected profile or quick-effect controls, make the small adjustment and save it to the device where the interface permits.
If the browser never offers the device, do not keep granting permissions to unrelated sites. Recheck the model on Razer's web list, try a supported current browser and return to the desktop Synapse 4 path when the device and operating system support it.
Browser permission is normally session-specific and should be limited to the intended device. Remove access when using a shared computer, and do not enter a Razer ID password into a page whose origin is not the official service. The independent checker on this site never asks for account credentials.
Use this Razer Synapse Web setup checklist before granting a browser access to a connected peripheral. The web service is a limited configuration path for selected devices, not a universal copy of the desktop application. A useful session depends on the exact product appearing on the Web list, current firmware, a compatible browser, a direct and stable connection, and permission being granted only to the official Razer origin.
Search the complete product name and RZ identifier in Razer Support article 20604. Do not substitute a Windows Synapse 4 or Mac Preview entry, because browser compatibility is maintained separately. If the exact model is missing, the browser service should be treated as unsupported for that device until Razer updates the list. A similar family name or on-board memory feature is not enough to create a confirmed Web result.
Use Razer's firmware guidance for the exact device before the session, then close desktop tools that may already hold the hardware connection. Connect directly when possible and avoid an unreliable hub during diagnosis. Open a current compatible browser and the official synapse.razer.com address. These steps give the Web service a clear opportunity to identify the product without another application, stale firmware or unstable connection obscuring the result.
Review the browser device picker and select only the intended peripheral. Do not approve an unfamiliar page, extension or look-alike domain, and never enter account credentials into an origin you have not verified. On a shared computer, remove device permission when the task is finished. The Razer Synapse Web setup checklist does not require this independent site to receive device access, account data or profile content.
Use the controls actually shown for the connected product, such as selected assignments, on-board profile changes or Chroma quick effects. Missing desktop modules, cloud workflows or advanced macros may be a limitation of the Web experience rather than a broken device. Save supported changes where the interface permits, disconnect cleanly and return to Synapse 4 when the operating system and product support the full desktop path.
This Razer Synapse Web setup checklist defines a successful browser session as an exact device match, current firmware, verified official origin, deliberate permission and usable supported controls. If detection fails, recheck those conditions before switching browsers or granting more access. If the required feature is outside the Web scope, use the appropriate desktop guide instead of treating a limited browser interface as a full Synapse replacement.
For selected supported devices, Synapse Web provides limited browser-based customization without the full desktop installation.
No. Confirm the exact device on Razer Support article 20604.
No. It provides a narrower set of quick browser controls and is not a complete replacement for the desktop app.
Check the compatibility list, update firmware, connect directly, grant browser device permission and close competing control software.
