138 lines of code

Just over two years ago, I committed the first 138 lines of Go code to the ntfy repository. A lot has changed since then: a lot more code, a lot more features, an iOS app, an Android app, a PWA, countless integrations into all sorts of tools, and lots of tutorials and videos from ntfy fans. Crazy!

But even though it looks as though everything changed, the basic idea behind ntfy's HTTP-based publish-subscribe mechanism remains the same as those original 138 lines of code.

In this blog post, in honor of your birthday, little ntfy-toddler, I'd like to show you all a little bit how ntfy is architected, and how its infrastructure is set up. I hope you'll enjoy it.
