You can see for yourself what buying a license includes in the list on the product's home page under "What's Inside": All by itself the free version of the program is phenomenal. The extras are just about entirely for professionals who intend to make a living using BG. The project makes a bit of extra coin to help keep things running by selling extras, but I've never found any of them to be necessary.
#BLUEGRIFFON IMPORT SITE SOFTWARE#
That is, it is free for everyone because various members of the community pitch-in to develop the software for everyone's benefit. The "you get what you pay for" concept doesn't really apply to BG because it is Open Source software. Then if you like it (and want more powerful tools).you buy the more advanced version (instead of someone else's product). The free version (free sample) gets you hooked.gets it's "foot in the door" so to speak. But I think that the basic rule of "You get what you pay for" applies. Now having said this I guess I could be wrong.since I have not personally used BlueGriffon. of a personally designed website (after you learn more about what exactly you want & need from a website).this is where the pay-for versions come into play. More than likely if you move up to version 2, version 3, etc. I'm willing to bet that the free version is great for making a basic website (for someone that has never done it before).and is sort of on "version 1" of their website.
If everyone using the free version of BlueGriffon could make an "exceptional website".then no one would purchase the pay-for versions.and the developer's of BlueGriffon would make no $$$. I think the keyword to your question is "exceptional". Five Essential HTML5 Editors | HTML Goodies
