splitforms or Slapform

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 — 500 free submissions total with unlimited forms, the full dashboard, automatic spam scoring, and a developer-first API. Pro adds signed webhooks, file uploads and exports for $5 per month. Both have a $5 per month paid tier; splitforms Pro includes 5,000 submissions a month to Slapform Hobby's 1,000.

Test, then cut over

Send a test entry, confirm it reaches your inbox and dashboard, then remove the old endpoint.

Common questions

Frequently asked questions.

View all FAQs
Is splitforms a real Slapform alternative?

Yes. splitforms handles the same core jobs as Slapform: a POST endpoint, email delivery, a submission dashboard, webhooks, and spam filtering. Slapform's free plan: 100 submissions per month, 1 form. splitforms Free is 500 submissions with no card and no time limit, on unlimited forms; for webhooks and exports, splitforms Pro is $5/month.

How long does it take to migrate from Slapform?

For an endpoint-based form service, create a SplitForms form and set the action to https://splitforms.com/f/YOUR_ACCESS_KEY. Alternatively, use /api/submit with a hidden access_key input. Preserve visitor fields, map provider-specific controls, then verify the deployed form, uploads and delivery settings.

Does splitforms support the same features as Slapform?

splitforms includes email delivery, a searchable dashboard, HMAC-signed webhooks on paid plans (8-second timeout, one automatic retry on network errors, timeouts and 5xx responses), storage-backed file uploads on eligible plans, custom redirects on every plan, smart spam filtering, and a documented REST API. Slapform-specific features like genuinely lightweight setup may need an integration.

What does splitforms cost compared to Slapform?

splitforms is free for 500 submissions total with no card; paid plans are $5 per month Pro (5,000 submissions per month) and $49 per year Annual (15,000 submissions per month, about $4.08 per month). At full use that is $1.00 per 1,000 submissions on Pro and $0.27 on Annual. Slapform starts at $5/month (Hobby — 1,000 submissions). Verify both pricing pages because allowances can change.

Will my existing Slapform forms break if I switch?

Your HTML can stay in place. Preserve field names, validation, and styling, change the action and access key, then test the production form before completing the switch.

Does splitforms have a yearly plan?

Yes — the Annual plan is $49 per year (about $4.08 per month) for 15,000 submissions/month with every Pro feature, billed once a year. Check Slapform's current pricing page before comparing billing terms.

Is splitforms a good fit for single-form hobby projects where minimal setup matters more than features?

splitforms is built for developers shipping production sites — static sites, SaaS landing pages, JAMstack apps, and agency client work. For single-form hobby projects where minimal setup matters more than features, the deciding factor is usually whether genuinely lightweight setup matters to you; if it does, keep Slapform in the mix. Otherwise splitforms is the endpoint-driven option.

Deep dive

The full picture, no fluff.

Short, honest answers on pricing, migration, and why teams move from Slapform to splitforms.

01

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 gives you unlimited forms on every plan, including Free.

The second trigger is webhook signing. Slapform has webhooks but the signing story is minimal. splitforms ships HMAC-SHA256 signed webhooks (one retry after ~2s on network errors, timeouts and 5xx; not on 4xx; 8-second timeout) on paid plans, plus a free webhook tester at splitforms.com/webhook-tester.

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.

Common Slapform issues splitforms solves

  • “I shipped a second form and now I'm paying $5 per month.”

    splitforms's free tier covers unlimited forms.

  • “I can't tell whether a webhook call was genuine.”

    splitforms signs every payload with HMAC-SHA256 (`sha256=` header prefix) so your receiver can verify it, and the free webhook tester at splitforms.com/webhook-tester shows the exact payload shape.

  • “I'm getting AI-written spam that the CAPTCHA can't catch.”

    splitforms's rule-based spam scoring checks links, phrases, disposable addresses and other content signals.

  • “I need a real API for a custom integration.”

    splitforms ships an open REST API on every plan.
