Razer Blade control utility

For those of you who

• own a Razer Blade 16 2023 or Razor Blade 14 2023
• use Windows 11
• Razer Synapse 3 (including the Beta) makes your eyes bleed
• baffled by why your fans are always at full-throttle
• and the battery depletes in just an hour

I have great news. I've reverse-engineered the Razer protocol and have crafted an alternative solution. A drop-in predictable and compact Razer Synapse alternative.

What can it control?

• Performance modes (including overclock)
• Lid logo modes: off, static, breathing
• Keyboard brightness (works on Windows with Fn keys anyway)

Reverse Engineering

Read about the reverse engineering process for Razer Blade 16 in data/README.md. You can follow the steps and adjust the utility for other Razer laptops.

Run razer-cli enumerate to get PID. Then razer-cli -p 0xPID info to check if the application works for your Razer device.
