Praqtor IMAGINE lets you select from 26 finished applications you can browse, watch, and try free in your browser — nothing to install, no account needed. Every template comes with a demo video, a screen-by-screen walkthrough, and a working app. The first template is open for building: make your own crossword book, free. Pick your options, a single-use code is emailed to you, the build runs in seconds, and the file is yours — with a build sheet showing exactly what changed and what did not.
