The full picture, no fluff.
Long-form prose for the developer who wants the substance behind the table — what each platform is actually good at, and what they're not.
§ 01
Short answer: which one should you pick?
Slapform is fine if you're shipping exactly one form on a hobby site and 100 submissions/month is the upper bound. It's straightforward and gets out of the way.
splitforms is the right call for anything more — 1,000 submissions/month free with unlimited forms, the full dashboard, AI spam classification, signed webhooks with retries, file uploads, and a developer-first API. Both have a $5/mo paid tier; splitforms covers 5x more on the free plan before that upgrade pressure kicks in.
§ 02
Why developers switch from Slapform to splitforms
The most common trigger is the per-form limit on Slapform's free tier. If you ship a second project, you're already paying. splitforms has no per-form cap on any plan.
The second trigger is webhook depth. Slapform has webhooks but the surrounding retry, signing, and dead-letter behavior is minimal. splitforms ships signed webhooks with retries and a dead-letter view on every plan.
The third trigger is dashboard usability. Slapform's UI is minimal — fine for a single form, less fine when you're managing several. splitforms's dashboard is built for fast cross-form inspection.
§ 03

Common Slapform issues splitforms solves
"I shipped a second form and now I'm paying $5/mo." splitforms's free tier covers unlimited forms.
"My webhook failed and there's no retry." splitforms retries with exponential backoff and surfaces failures in a dead-letter view.
"I'm getting AI-written spam that the CAPTCHA can't catch." splitforms's classifier is trained on modern form spam.
"I need a real API for a custom integration." splitforms ships an open REST API on every plan.
