Synapse Killer V2.0 (Updated 2025)

Keep your Razer configs without Synapse's bloatware running in the background.

How It Works

This Project was made in C# and built into an executable.

It provides a way to use your Razer Configs without any Razer Synapse Services running.
SynapseKiller freezes and destroys all Razer Services allowing configs to be loaded first.

It does not keep any active processes, only runs until all services are handled.

Functionality

• Listen for processes
• Enable, Disable Processes
• Runs On Startup (Optional)

How to Install

Exe	Description	Releases
	Enable or disable all synapse services	Download

Run on Boot

• Press WIN + R to open Run Console --> Write shell:startup and press OK.
• Move SynapseKiller.exe executable into the folder.

Configuration

• After running the app you should find the skconfig.txt in your documents folder.
• The first line must be pointing to Razer App executable, all the other lines are services.
• The last line is the time in seconds to load razer configs before destroying synapse.
