The quadplay✜ fantasy console by CasualEffects is now in public beta.


Join the Beta

This beta version operates only in Pro mode, using external editors. The 1.0 release will also provide a complete web-based IDE that requires no local installation.

To get started in Pro mode, you’ll need Windows, MacOS, or Linux and the following freely-available software.



See the manual for a getting started guide, the change log, road map, and beta notes.
