I am developing a web application and later I will sell it on CodeCanyon. As a backend developer, I’m usually having problems with UI designs and decided to use some UI toolkits distributed on the web. But there are tons of licenses and I don’t get which license allows me to use their UI toolkits in my commercial product. In other words, which license allows me to use their UI toolkit in my commercial product which I am planning to resell on CodeCanyon?
Can you please guide me on this?
