I have 3 laptops and 2 Raspberry Pis: one or more of them is always online, couldn't I use them as my own CDN to serve a static website?

As per my previous post, Free hosting from for profit companies like Heroku, Slack etc doesn’t work. Don’t depend on it! Only viable long term solution is for the UN Black Helicopters :-) i.e. the government needs to offer hosting, I don’t really trust “the Cloud” especially “free” cloud sesrvices.

The whole notion of clients and servers is silly in 2022.

- Check out my N70 running the Nokia open source port of Apache, Raccoon at: http://roland.tanglao.guest.at.openlaboratory.net/ <– too bad nothing came of it, all computers are servers and clients in 2022 it seems to me! If a Nokia phone could run a server in 2022 than my laptops and Pis can run servers in 2022!!!!!!!!
