What are the best online form builders?

HubSpot Forms - great for logic branching, payment collection, analytics, and triggering automated outreach or follow up workflows. For logic, professional licensing is required, so if you're cost sensitive, you may want to look at other options. By far, HubSpot's online form builder is one of the most robust in the marketplace, you just need to be using HubSpot, and in most instances, a paid version to get the features you want.

Jotform - great for logic branching, adding multiple files, and collecting electronic signatures. Jotform is a cost effective solution vs. some of the full CRM tech stacks that offer form creation, i.e., HubSpot and Salesforce. One advantage of Jotform is their offline form collection ability. Even when you don't have wifi or cell service, you can use the Jotform mobile app to enter information, and when you come online again, the data flows through. Jotform connects will all the big tech stacks as well.
