Welcome to the
Software Library

The Plausible Labs Software Library consists of gourmet commercial and open source ingredients ready to enhance and improve your applications. You’ll find them being used in all sorts of apps, like comiXology’s Comics app and of course in our own creations like Peeps.

Sharing solutions like these promotes a healthier developer community and enables better, more useful applications for everyone.
