Founder of keygen.sh here. Thanks for the mention. Bummer you didn't know of it before, but I'm really working on improving SEO so hopefully that'll change for the next person. I actually checked out the source code for Lunar awhile back while digging around seeing how devs use Sparkle, since I've been working on an integration there for auto upgrades, along with a Swift SDK. Let me know if you ever hit a point with your licensing server where you want to check Keygen out. I'd be happy to chat. Also curious -- from your OP re: Crystal: > It’s been a joy to work with it! The standard library for working with strings, JSON, YAML and XML is top notch. Type safe and extremely fast, very important characteristics for a licensing server that is queried hundreds of times a second. You said you're doing ~$3.5k/mo in licenses for Lunar. Where's the licensing volume coming from here? Keygen handles licensing for hundreds of products and millions of devices and I very rarely hit 100 RPS even on a busy day, so kind of curious how your licensing is setup to produce that much volume. :)
