Installing Wappler on either Windows or Mac is pretty basic, just take the defaults and everything should install just fine. Once you’re into the application, you’ll need to create an account for logging in.
Wappler.io has a free trial so you can get a feel for what it can do. The trial isn’t designed for you to learn everything about the product for free, but rather, it gives you a taste of all it can do. I remember getting to the end of the free period and realized it would take another month to know if it was the right tool for me in building web and mobile applications. The risk is low since it is a month subscription, so I always encourage people to just jump in and invest a month in sandboxing some ideas.
