MuxForms is a hosted form backend and inbox. You design a form once, embed it on websites or POST JSON from apps, and read every submission in one dashboard.

How much does MuxForms cost?

Three plans: Free includes 1 form and 50 submissions per month. Pro is $9/month with unlimited forms and properties (7-day trial after checkout). Team is $29/month with shared workspaces, invites, and submission assignment. Details on the pricing page.

Does MuxForms work with Next.js and WordPress?

Yes. Add the embed script or call the submit API. Allow each site origin on the form so browser submissions are accepted.

Can mobile apps use the same inbox as the website?

Yes. POST JSON from Expo or React Native with the same form id. Website and app submissions appear together.

Is MuxForms a Typeform alternative?

MuxForms is a backend for your own UI, not a hosted survey experience. Use it when the form lives on your site or in your app.

How does MuxForms reduce spam?

Honeypot fields, rate limits, schema validation, optional Turnstile, CORS allowlists for browsers, and ingest secrets for server or native clients.

Why MuxForms

Forms are easy. Form infrastructure is not.

Most teams do not need another form builder. They need one pipe that works on every site and app — without copying SMTP and spam setup for the twentieth time.

Without a shared backend

Every project needs its own form stack

A new contact form on the marketing site. A feedback widget in the app. A waitlist on a landing page. Each one means another plugin, another API route, another inbox you will forget to check.

Data lives in ten different places

WordPress emails, Expo payloads, Netlify Forms, Google Sheets, and random inboxes. When a lead writes, you hunt. When you want a report, you copy-paste.

Setup is heavier than the form itself

CORS, spam, schema, SMTP, domain verification — all over again for every property. You ship the product, then burn an evening wiring a “simple” Get in touch page.

With MuxForms

One form backend. Every property.

Drop a script on a website or POST JSON from a mobile app. Same dashboard, same schema, same inbox — whether you have two projects or twenty.

All submissions in one inbox

Feedback, leads, support, waitlists, and anything else a form can capture lands in one Postgres inbox. Search it. Get an email from one verified domain.

Minutes, not a weekend

Live fields, validation, honeypot, rate limits, CORS, and email notifications are already on. You design the form. MuxForms does the plumbing.

Why this exists

Built because rebuilding forms 20 times is a bad business.

MuxForms started as the missing backend for 10 mobile apps and 10 websites: get in touch, talk to leads, collect feedback, bookings, waitlists — anything a visitor or user might send.

Setting that up per project was the expensive part. Plugins, serverless routes, spam filters, email domains, dashboards that never talked to each other.

So MuxForms is a shared form backend: web embed or native REST. Validate. Store. Email. Repeat across every property without starting over. Read the story.

How you connect

One form. Website embed or mobile API.

Websites: one embed script

The script reads data-form-id, fetches the layout, renders fields, and submits. Next.js, WordPress, or static HTML. Embed docs.

HTML

<div data-form-id="FORM_UUID"></div>
<script src="https://www.muxforms.com/embed.js"></script>

Mobile: POST JSON

Expo and React Native keep their own UI. Hit the same endpoint. Submissions join website forms in one inbox. Submit API.

HTTP

await fetch(`https://www.muxforms.com/api/v1/forms/${id}/submit`, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ email, message }),
});

Compared to the usual suspects

A form backend, not another form builder.

Typeform and Google Forms host the page. MuxForms hosts the ingest. If you already have a site or an app, you want the pipe, not a new branded flow. See comparisons.
