Short answer: which one should you pick?
Kwes Forms is the right call if you specifically want declarative client-side validation driven by HTML attributes — `data-kwes-rules="required|email"` and you're done. The polish is real, and it's particularly comfortable in Webflow projects where a designer is wiring the form without writing JS.
splitforms is the right call when you want the backend to do its job (storage, classification, notification, webhooks) and you're picking your own validation stack — native HTML validation, Zod + React Hook Form, Yup, whatever. splitforms doesn't require a runtime dependency in your page, doesn't dictate validation UI, and gives you a larger free tier with a more developer-first API.
§ 02
Why developers switch from Kwes Forms to splitforms
The most common trigger is the runtime dependency. Kwes Forms requires loading their client-side JS bundle for validation to work. If you care about page weight, CSP rules, or want to ship a form that works without JavaScript, the dependency becomes friction. splitforms ships a backend — your validation is whatever you choose, including no JS at all.
The second trigger is pricing per form-count. Kwes Forms tiers on form count in addition to submission volume. Running a portfolio with multiple landing-page forms, or an agency with several client sites, hits the cap fast. splitforms has no per-form limit on any tier.
The third trigger is webhook depth. Kwes Forms supports webhooks, but the surrounding retry, signing, and dead-letter behavior is less mature than splitforms's. For a production integration, signed payloads with retries matter.
