OK. Here's another "developing in the open" post.
I've written an #ActivityPub server which can be deployed as a *single* #PHP file.
No databases, no libraries, no dependencies, no frameworks. Also, no advanced features!
It is currently powering the user example@example.viii.fi
I am looking for alpha testers. All you need is a domain, PHP 8, and the ability to add a custom .htaccess rule to your server.
If you'd like to try it out & give me feedback, please drop me a message.
