At least let me download a simple generated demo for me to see. Instead of forcing me to signup to have my email, forget about getting money from it. You just owe me my email and i feel very bad about it, i feel cheated)

More than that, i'm having similar functionalities like yours, but with realtime data/views, SSR/static views, fully SPA.
If someone's interested, i could easily bundle for users to generate, too.
