i think the new common lisp web/gui framework CLOG [0] thats being developped by david botton is a good competitor to IHP. it is also 100% free
Also nothing wrong with IHP offering commercial features. Developers need to eat.
i believe they do. CLOG is very well suited for spa and db driven web applications and they both have a builder application [0]. but yes CLOG does have more uses than just making websites
nothing wrong with charging for things but we should definitely appreciate things that are done for free
