</form>Webflow + Waitlist
Webflow's built-in form block sends to Webflow's own backend, which caps at 100 submissions/month on the free plan and lacks webhook delivery, CC recipients, and spam filtering. The waitlist on this page bypasses that entirely — paste it into a custom embed element, set the form action to splitforms, and you get 200 dashboard submissions total with AI spam filtering; Starter adds Slack/Discord webhooks. Webflow's native interactions (success message, loading state) still work if you use fetch instead of a native form submit.

Waitlist fields
The posted payload contains email, name, how did you hear about us?. Required fields are email. Rename, remove, or add your own — splitforms accepts any name you POST.

Template playbook
Waitlists are the cheapest growth tool a pre-launch product has — Superhuman, Notion, and Linear all built sizable waitlists before paid launch. The form captures email plus a question or two on use case ('what would you use this for?', 'what tools do you use today?') so the launch sequence segments by intent. Multi-step flow boosts completion vs a single form — the prospect commits in step 1 and answers the qualifying questions in step 2-3 with momentum. Push waitlist signups to a dedicated ESP audience (Loops, ConvertKit, Beehiiv) so launch-day emails segment by use case and target the highest-intent signups first.

Setup
Three actions stand between you and your first waitlist submission — no backend, no database, no CAPTCHA library.

Testimonials
40 quotes on record — from indie hacks to agency migrations.
“Migrating off Basin was painless — same form markup, just a new action URL. I kept my forms and lost the per-submission anxiety.”
“The spam-test tool let me prove the honeypot worked before I trusted it in production. I love a product that hands you the test, not just the promise.”
“Two forms on the free plan was exactly enough for my landing page and my newsletter. I upgraded to a paid plan only when the third form arrived.”
“I built the HTML in your generator, copied it, and the form was live in two minutes. The fastest zero-to-working form I've ever set up.”
“Our Gatsby marketing site needed a contact form without a serverless function per environment. splitforms removed an entire category of config.”
“Submissions are isolated per account with row-level security. As someone who reviews vendors for a living, the /security page told me everything I needed.”
Common questions
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Webflow site without server-side code, plugins, or SDKs. Drop the snippet into a Webflow page or component and submissions land in your splitforms dashboard.
Free for 200 submissions total — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.
Yes. The template ships with sensible defaults (email, name, how did you hear about us?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.
A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on Webflow as on any other framework.
Yes. Webhooks are available on paid plans, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.
Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.
Showing 'you're #347 in line' on the confirmation creates social proof but invites comparison. Showing total waitlist size ('join 2,500 people on the waitlist') without per-person position is the safer middle. Refer-a-friend mechanics that move people up the list (Robinhood-style) drive viral growth but require more eng work.
Tag waitlist signups by use case in the ESP audience (Loops, ConvertKit). Launch-day, segment by tag and send invite waves over 48-72 hours. Highest-intent / closest-fit goes first; broadest casts go last. Spreads server load and lets you triage onboarding support.
Yes — webhook the JSON. Loops has direct webhook support and is purpose-built for product transactional + waitlist email. ConvertKit and Beehiiv accept via API or Zapier. All three handle the launch-sequence segmentation cleanly.
