I'm working on an end-to-end encrypted alternative to Google Forms (because Google is creepy).
It has all the same features plus many more: advanced conditional branching, webhooks, thorough design customisation, better question types (e.g. address autocomplete), etc.
I've bootstrapped it into a (very) small startup. The idea is to maintain an ethics- and privacy-driven form builder that people don't have to trust, since nobody can see your responses. It also makes GDPR way easier for you!
