libratbag as a Linux alternative to Razer Synapse
Updated
Our verdict
libratbag is a viable replacement for Razer Synapse on Linux, but with important caveats. It supports many Razer mice through reverse-engineered protocols, allowing DPI adjustment, button remapping, and profile storage. However, RGB lighting control is not supported—this is a hard limitation. Users who prioritize functionality over lighting will find libratbag sufficient, especially with GUI frontends like Piper. Support is community-driven and device-specific, so compatibility varies. It won’t replace Synapse fully for all users, but for core mouse configuration without lighting, it’s the best available option on Linux.

What works the same
- Supports DPI and polling rate customization
- Allows button remapping and macro creation
- Stores multiple profiles directly on the device
- Applies settings without requiring a running background service
- Supports hotplugging and automatic profile loading
What is different
- No RGB lighting control or effects—this is not supported at all
- Limited to mice; does not support Razer keyboards or headsets
- Relies on community reverse-engineering, so not all Razer devices are supported
- Fewer polished GUI tools compared to Synapse's integrated interface
- No cloud profile sync—settings are local only
Opening your Razer Synapse files
There is no compatibility with Razer Synapse configuration files. libratbag uses its own internal format and does not import .ratp or other Synapse-specific files. Configuration is done from scratch within libratbag-compatible tools. Exporting settings is possible in some frontends, but not standardized. Migration must be manual: settings from Synapse cannot be transferred directly and must be reconfigured on Linux.
Switching from Razer Synapse to libratbag, step by step
- Install libratbag via your distribution’s package manager (e.g., 'sudo apt install libratbag' on Debian/Ubuntu)
- Install a GUI frontend like Piper if preferred ('sudo apt install piper')
- Connect your Razer mouse and verify it’s detected by running 'ratbagctl list'
- Use Piper or 'ratbagctl' to configure DPI, buttons, and profiles
- Save settings—most are stored on the device itself
- Test hotplugging; ensure profiles persist across reboots
Key features of libratbag
- Configurable DPI and polling rate
- Button remapping and macro support
- Per‑profile device settings
- Support for multiple devices simultaneously
- CLI and GUI tools
- Open‑source community maintained
- Cross‑distribution packaging
How to install libratbag on Linux
sudo apt install libratbagsudo apt install libratbagsudo dnf install libratbagsudo pacman -S libratbagsudo zypper install libratbagFrequently asked questions
Does libratbag work with all Razer mice?
No. Support depends on reverse-engineered drivers. Common models like the DeathAdder V2 or Naga Trinity are supported, but others may not be. Check the libratbag GitHub issue tracker for your specific model.
Can I control RGB lighting with libratbag?
No. libratbag does not support RGB lighting configuration. That functionality is absent and not planned. Use Razer Synapse on Windows or a dual-boot for lighting control.
Do I need to run a service in the background?
Yes. The libratbag daemon (ratbagd) must be running. Most distributions enable it by default, but ensure it’s active for GUI tools and hotplug support.
