Conditional logic, file uploads, electronic signatures, and webhooks can help you assess form behavior and what follows a response; deployment model and monthly submissions add operational context. Check free-plan availability and paid-from pricing as well. The ranking opens with Endatix, Feathery, and OpnForm, with Basin and Paperform also among the first entries. Consider which listed features fit the information you need to gather and how you expect to manage incoming submissions.
