Always when I have an idea for a small side project, I find someone that has already built it, but open source, for free and with even more/better features I had in mind 😂

What do you use to host your #buildinpublic projects?

Some PaaS like Vercel, Cloud Computing on AWS or some VM / Server Provider like. Hetzner?
