Woah that's super cool, like that they describe clearly how the relay works and how to spawn yours.

Not sure if you're trolling: https://happy.engineering/docs/how-it-works/

I'm not trolling at all, I genuinely liked that it's not some pay-to-use, SaaS, startup or whatever, but an actual simple and functional tool, free, open source, documented.

Then I misinterpreted your message, sorry (:
