Everything on the site is part of the core library which is free and open source, except for the stuff clearly marked as part of pro, which has a link to the pricing. (Plus, you really don't need pro, all the good stuff is free.) I think it would be more misleading to put pro on the front page, because that would make people think it's a subpar experience without it.
