JavaScript + Waitlist

Built for JavaScript developers who hate operating a backend.

Vanilla JavaScript gives you full control over the form lifecycle — event listeners, validation, AJAX submission — without framework overhead. The waitlist on this page uses addEventListener('submit'), new FormData(), and fetch() to POST to splitforms. No jQuery, no Axios, no polyfill. This is the lightest possible integration: zero dependencies, zero build step, zero bundle-size impact. Perfect for sites where every byte matters — landing pages, marketing sites, and progressive-enhancement scenarios.

Waitlist fields

What every field actually does.

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.

Email — Reply-to address — splitforms wires this so hitting reply goes back to the sender.
Name — Greeting + dashboard label so submissions don't all read 'anonymous'.
How did you hear about us? — Dropdown — keeps responses normalised so you can filter the dashboard.

Template playbook

The reason this waitlist exists.

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.

Step 1: capture email
Step 2-3: qualify use case

How SplitForms works

What happens after someone submits your form?

splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.

Where can submissions go besides email?

On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.

Common questions

Waitlist on JavaScript — answered.

View all FAQs

Does this waitlist work on JavaScript?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any JavaScript site without server-side code, plugins, or SDKs. Drop the snippet into a JavaScript page or component and submissions land in your splitforms dashboard.

How much does the waitlist cost on JavaScript?

Free for 500 submissions — no credit card, no time limit. Pro is $5/mo for 5,000 submissions a month, and Annual is $49/year for 15,000 submissions a month. The same pricing applies regardless of which framework hosts the form.

Can I customize the fields?

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.

How does spam protection work on the waitlist?

A hidden honeypot field catches dumb bots, and a rule-based filter scores the rest; anything that looks like spam goes to a separate Spam tab instead of your inbox. No CAPTCHA, no friction for human users — and it works the same on JavaScript as on any other framework.

Can I send the waitlist submissions to Slack or Discord?

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.

Will it work on a static JavaScript site?

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.

Should I show waitlist position / numbers?

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.

How do I trigger launch invites in waves?

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.

Can I integrate with Loops / ConvertKit / Beehiiv?

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.
