What is Contact form?

Contact form is one of 590+ free widgets on PlanckUi. A contact form with a spam-proof backend. Collecting testimonials, feedback and requests is how a business learns what to build — and gets the raw material for its own social proof.

Share the link after a purchase, in an email signature, or embed the form right on your site.

Everything is rendered in an isolated shadow DOM, so it can never conflict with your site's own styles — and at a few kilobytes, it won't move your page speed.

Everything included

  • A contact form with a spam-proof backend.
  • Free forever — no watermark, no usage limits, no "upgrade to remove"
  • Customize everything: colors, fonts, corner radius, shadows, dark mode
  • Copy-paste install: one snippet of HTML works on any website builder

Add Contact form to your website in 3 steps

  1. Customize it. Use the Paint editor right on this page — set your colors, fonts, radius and content. Contact form updates live as you change things.
  2. Copy the HTML. One click gives you a self-contained snippet. No account needed, nothing to install, no script from our servers.
  3. Paste it on your site. Paste it anywhere HTML goes: your site, a landing page, WordPress, Webflow, Wix, Squarespace, Shopify, Ghost — if it renders HTML, it works.

Contact form is free on PlanckUi — the same embed runs $15–40/month on Elfsight or Common Ninja. No watermark, no usage limits, no credit card.

Frequently asked questions

Is Contact form really free?
Yes — completely. PlanckUi widgets are free forever, with no watermark, no usage limits and no credit card. Paid widget platforms charge $15–40 per month for the same embeds.
Do I need an account to use Contact form?
No. Click "Copy HTML" and paste it on your site — that's the whole flow. An account is only needed if you want to collect live data (like customer testimonials) and manage it from a workspace.
Does it work on Wix, Squarespace, Webflow, WordPress or Shopify?
Yes. If a platform lets you paste an HTML embed block — and all of them do — Contact form works there. The snippet is plain HTML and CSS in an isolated shadow root, so it can't fight with your theme.
Will Contact form slow down my website?
No. The widget is a few kilobytes of HTML and CSS rendered locally in your browser — no external requests, no tracking scripts, no layout shift.
