A single PHP file which acts as a basic ActivityPub server. This is designed to be a lightweight educational tool to show you the basics of how ActivityPub works. There are no tests, no checks, no security features, no header verifications, no containers, no gods, no masters. Needs only PHP v8.3 with OpenSSL turned on, an HTTPS certificate in for the web server, and about 50 megs of disk space for data storage.

I actively do not want you to use this code in production. It is not suitable for anything other than educational use. The use of AGPL is designed to be an incentive for you to learn from this software and then write something better. It is the nadir of bad coding. There are no tests, bugger-all security, scalability isn't considered, and it is a mess. But it works.
