Bit clickbait.
tldr: ffmpeg used it in their github actions, which pulls from gmp. They also use 100 builds to do simultaneous testing. Forks also run the actions, and it all pounds the gmp servers.
My personal instance is 2 vcpu 1gb ram and 30gb storage. It’s just me using it, but it’s running rather decently, so maybe if it’s just a few people you could get away with something like that
