You probably got here because you saw some requests to this domain from another website and are wondering what they are about. Good on you for being curious!
cdn.baltpeter.io is the domain I (Benjamin Altpeter) use for hosting various static files and assets for some of my projects.
If you want to learn more about what I do, have a look at my personal website or follow me on Twitter for the occasional link to something cool I found on the internet. For any questions, feel free to send me an email.
