How Reachase iframe embeds work

March 8, 2026

Why we ship hosted iframe widgets and how to customize them to match your brand.

Maya Okonkwo · Engineering

Reachase widgets are hosted on our infrastructure and embedded on your site with a simple iframe snippet. That keeps submission handling, validation, and spam protection on our side while your marketing site stays static.

You copy an embed URL from the dashboard, paste the iframe into your page, and submissions flow into Reachase without extra backend code on your host.

Styled to match your brand

Contact forms include an Appearance editor with presets and custom colors, fonts, border radius, and button labels. The live preview in the dashboard matches what visitors see in the iframe.

That means you skip custom form CSS on every site you ship.

Works with static sites

Iframe embeds work on any HTML page, static export, or CMS. No framework-specific SDK is required for basic contact forms and scheduling widgets.

Works with Next.js static export, Astro, Hugo, and plain HTML.
No API routes required on your host for form submissions.
Customize appearance from the dashboard without redeploying your site.

Security and isolation

Iframes provide a clear security boundary between your page and the hosted widget. Submissions are validated server-side against your configured fields, rate limited, and delivered via email or webhooks.
