When comparing these two products, the main differences that stand out are cost, plan limits, and overall design philosophy.
KwesForms's "Bronze" plan starts at $19/month with 1,000 submissions and 5 forms. Compare that to Submit JSON's $5/month plan with a submission limit of 2,500 and 10 forms. Submit JSON's plans offer 2.5 times (250%) more submissions on average with a comparable feature set.
KwesForm's target customer is non-technical folks, so it comes with a few bells and whistles that Submit JSON will never have, like a form builder and front end input validation.
Regardless, it's another Formspree clone. KwesForm's "low-code" HTML-first approach is misguided, where the cons outweigh the pros.
In comparison, Submit JSON's API-first approach is more versitile, secure, and aligned with modern web development best practices.
Which is the best form backend for you? We think the answer is obvious, but we'll let you decide.
