§ 03Deep dive6 sections · honest take

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 — 500 submissions/month free with 2 forms, the full dashboard, AI spam classification, and a developer-first API. Starter adds signed webhooks, notification emails, retained file uploads, and exports for $1/month. 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 gives you 2 forms on Free, 10 on Starter, and unlimited forms on Pro plus 3-Year.

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 Starter and above.

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

§ 04

Common Slapform issues splitforms solves

"I'm getting AI-written spam that the CAPTCHA can't catch." splitforms's classifier is trained on modern form spam.

STEP 01SIGN UP

Get a free splitforms access key

Sign up at splitforms.com with your email. No credit card. The free tier covers 500 submissions/month — more than enough to validate the migration before you commit to anything.

STEP 02SWAP URL

  action="https://splitforms.com/api/submit"
  method="POST"
>
  <input type="hidden" name="access_key" value="YOUR_KEY" />
  <input name="email" type="email" required />
  <textarea name="message"></textarea>
  <button type="submit">Send</button>
</form>

STEP 03DEPLOY

Test, then deploy

§ 07Questions7 answered

Things developers ask before they switch.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Is splitforms actually a viable Slapform alternative?

Yes. splitforms covers the same core jobs as Slapform — POST endpoint, email delivery, dashboard, webhooks, spam filtering — at a lower price point with a larger free tier (500 submissions/month vs 100 submissions/month, 1 form). Migration is a one-line change to your form's action URL.

02How long does it take to migrate from Slapform?

For a typical site with one to five forms, migration takes about 10 minutes: sign up at splitforms.com, get an access key, swap the action URL on each form, deploy, and submit a test entry. No SDK changes are required for vanilla HTML forms.

03Does splitforms support the same features as Slapform?

splitforms supports email delivery, a real submission dashboard with search and export, webhook delivery with retries, Storage-backed file uploads, CC/BCC recipients, custom redirect URLs, AI spam classification on top of honeypot, and a documented REST API. Specific Slapform features like genuinely lightweight setup may require a webhook integration on splitforms.

04What does splitforms cost compared to Slapform?

splitforms is free for 500 submissions/month, $5/mo for 5,000 submissions, and $59 every 3 years for 15,000 submissions/month over 36 months on the 3-Year plan. Slapform starts at $5/month (Hobby — 1,000 submissions). For most use cases, splitforms is meaningfully cheaper at the same submission volume.

05Will my existing Slapform forms break if I switch?

No. The HTML form itself doesn't change — only the action attribute. Existing field names, validation, and styling all work identically. The only practical change is where the POST goes.

06Does splitforms have a long-term plan?

Yes — the 3-Year plan is $59 every 3 years for 36 months of access at 15,000 submissions/month, with no monthly billing during that span. Slapform does not currently offer a long-term plan.

07Is 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, agency client work. If your specific need is single-form hobby projects where minimal setup matters more than features., evaluate whether genuinely lightweight setup is decisive for you. If not, splitforms is likely the better economic and technical fit.
