Razer Synapse

Overview

Razer Synapse is Razer’s control and lighting software for compatible peripherals. It suits players who want to tailor Razer gear’s buttons, macros, performance and RGB behavior in one place. Its breadth of controls and support for Synapse 3 devices are useful, but device compatibility and the limited Mac release matter before committing.

Synapse 4 can import selected profiles, macros and Chroma effects from Synapse 3, so moving to the newer software need not mean rebuilding every setup. Razer says its multi-threaded architecture isolates device processes, allowing one device’s installation or upgrade to proceed without interrupting others in use. It also claims processing is up to 30% faster than Synapse 3; actual improvement may vary with usage, software and power settings.

Key features

• Device controls: Remap buttons, create macros and adjust performance settings for compatible Razer devices. Hypershift adds a secondary set of button functions; Rapid Trigger and advanced macros serve users who want more specialized controls.
• Lighting: Synapse supports addressable RGB control, lighting profiles, cross-device syncing and game lighting effects through Chroma RGB. Chroma also supports enabled accessories from more than 50 third-party hardware partners, making it useful for users with a mixed lighting setup, though compatibility remains device-dependent.
• Browser customization: Compatible devices can use browser-based quick controls, including onboard profiles and Chroma RGB quick effects. This is a convenient option for quick changes, but it does not remove the need to confirm device support.
• Profile migration: A migration tool transfers Synapse 3 profiles, macros and Chroma effects, and lets users select profiles individually. That is particularly helpful when only some old setups need to move forward.

Pricing

Synapse is free, with no free trial because there is no paid plan to trial. Razer offers Windows and Mac downloads as well as browser customization. The zero-cost model makes it a practical choice for compatible Razer owners; its value is less clear if your peripherals are outside that ecosystem.

Platforms

Synapse supports Windows 11 x86-64 and Windows 10. The Mac release is a preview for macOS 15 Sequoia and later on Apple silicon Macs, so Mac users should weigh that narrower support against the fuller Windows options. Browser-based quick customization is also available for compatible devices.

Who it's for

Synapse fits owners of compatible Razer keyboards, mice and other devices who want remapping, macros, performance tuning and coordinated lighting without paying for the software. It is also a sensible upgrade path for Synapse 3 users whose devices appear on Razer’s compatibility list. Users with unsupported devices, or those needing a broadly supported Mac release, should look elsewhere.

Pros and cons

• Pro: Button remapping, macros, performance settings and lighting controls are brought together for compatible Razer gear.
• Pro: Individual profile migration can preserve selected Synapse 3 macros and Chroma effects without moving every profile.
• Pro: Browser quick controls offer onboard-profile and lighting adjustments without relying solely on the desktop workflow.
• Con: Device support depends on Razer’s compatibility list, limiting usefulness for owners of other brands or unlisted gear.
• Con: Mac support is a preview restricted to macOS 15 or later on Apple silicon, which excludes earlier systems and Intel Macs.

Alternatives

Logi Options+ is a better fit for supported Logitech devices; its free plan supports Windows 10 or later and macOS 12 or later.

Rapoo A HUB is another free option with Windows, Mac and web platforms.

Logitech G HUB suits Logitech G users looking for free LIGHTSYNC RGB customization, device configuration, presets and game profiles.

Glorious CORE is worth considering for configuring supported Glorious products; cloud profile saving requires a Glorious ID.

Rebind is an option for users who want a free software mode with Luau scripting and support across Linux, Mac and Windows.

be quiet! IO Center is another free peripheral-software alternative.

Akko Cloud Driver is a free option with web, Windows and Mac platforms.

Fnatic OP Software is a free option for Windows and Mac.

Verdict

Choose Synapse if you own compatible Razer gear and want its controls, macros and Chroma lighting in a free package, especially if you are bringing selected setups forward from Synapse 3. Look elsewhere if your devices are not on Razer’s compatibility list or you need full Mac support beyond the current preview.
