First release, for the Razer Viper V3 Pro on Windows 10/11, wired or through the HyperSpeed / HyperPolling dongle. One executable of about 1 MB: no installer, no services, no account. Download freenapse.exe below; freenapse.exe.sha256 has its checksum.

Tray app

  • Battery percentage and charging state; live DPI stage and polling rate switching
  • Per-game profiles (DPI stage, polling rate, button layout) switched with the foreground window; games found automatically in Steam, Epic, GOG, EA app, Battle.net, Riot, Ubisoft Connect, Rockstar and the Xbox app
  • In-game polling rate: a higher rate only while a game is running
  • Macros recorded in the window or written in the config, played once, N times, while held, as a toggle or as a sequence (the Viper V3 Pro has no macro memory, so the tray app plays them, like Synapse does)
  • Start at login

Settings window and CLI

  • Native Win32/GDI window with the Customize, Performance, Calibration, Power, Games and Roadmap pages, plus app settings with the onboard profile selector and dongle pairing
  • freenapse status, config, apply, import and one command per setting; a TOML config file in %APPDATA%\freenapse or next to the executable for portable use

Good to know

  • Tested on one mouse. Other Razer mice are not supported yet.
  • Do not keep Synapse running alongside: it rewrites the settings it thinks it owns within seconds.
  • Use at your own risk; see NOTICE.md for trademarks and provenance.
