Razer Synapse vs Rebind

Razer Synapse is software for controlling and customizing Razer devices, including button remapping, macros, performance settings, and lighting. Hypershift provides a secondary set of button functions, while Rapid Trigger and advanced macros are also listed. Browser-based quick customization for compatible devices includes onboard profiles and Chroma RGB effects. Synapse 4 works with Synapse 3 devices subject to Razer's compatibility list, and a migration tool can transfer selected profiles, macros, and Chroma effects. The software is available for Windows 11 x86-64 and Windows 10; a Mac preview is available for macOS 15 Sequoia and later on Apple silicon Macs. Razer describes Chroma RGB integration with PC games and lighting effects on devices. The page offers Windows and Mac downloads and browser customization, but does not state a price. Which features are available depends on device compatibility.

Rebind is a keyboard and mouse remapping engine for Windows, macOS, and Linux. Its free software mode runs Luau scripts and supports macros, sensitivity controls, per-app controls, and per-game profiles; it does not require an account or Rebind Link. Free scripts without source protection can be installed as a guest, while paid marketplace scripts require signing in and buying with credits. Developers can connect tools through Luau, HTTP, or TypeScript, Python, and Rust clients. An MCP server supports screenshots, keyboard and mouse actions, and script execution. The optional Rebind Link adds physical USB keyboard and mouse output, a dedicated onboard processor, multi-device support, and a report rate up to 8,000 Hz. It costs $199, paid once and includes 12 months of Pro, with no recurring device-license fee. The Link is backordered, and hardware attachment requires Windows or macOS; Linux capture is not implemented.
