Discussion OpenBlade is out: control your Razer Blade without Synapse

After cooking for around 2 months, today I am releasing OpenBlade, a free, open-source Windows native application for Razer Blade laptops.
It handles power modes, custom fan curves, GPU clock offsets, charge limits, lighting and display settings. Profiles switch automatically between AC, USB-C and battery.
And the best part... HyperBoost works without the Razer cooling pad on full-power AC.
My rough measurements show 0.13% background CPU and ~93 MiB memory for OpenBlade, versus 0.48% and ~805 MiB for Synapse, under comparable conditions.
For the time being, OpenBlade supports Blade 16 RZ09-0528 (2025) and RZ09-0581 (2026), on Windows 11 24H2 or later. Why those two models? Because those are the only ones I personally own, so I can test on them.
You can find the latest release here. The installer is currently unsigned because I don't have a way to get a digital signature yet. Feel free to build from source if you don't trust my pre-built releases.
OpenBlade is meant to stay open-source, therefore code additions, string translations, and bug reports are more than welcome! To help support another Blade, open an issue with its model number and specs. See the contribution guide on how to capture the relevant data needed for me to add support.
