Seeds generated here now are verifiable :)
So, I did this based on FSGOptimizerSeedBank and it runs the generator you want locally, downloading it from a media fire directory that I created, with all the generators already ready to go, all the generators from the media fire is on my repl profile, wich I just changed some things for it to work with the hotkey.
It is required to have python3 and wsl, here's how to install: FSGOptimizerSeedBank
And it is required to have pip on wsl, you can install using this command:
sudo apt-get install python3-pip
Change the settings.json file with the generator you want(from the supported generators) to use and then just open the hotkey file, and with minecraft open, press Y to use it.
And also don't forget to change the minecraft folder(on the hotkey script) with where your minecraft saves are.
The supported generators in the website
