FormSubmit vs Basin: which form backend should you use?

An honest comparison of FormSubmit and Basin — approach, features, spam protection, integrations and when to choose each.

2 min readUpdated Sep 28, 2026

FormSubmit and Basin both help you collect form submissions without building your own backend, but they take different approaches. Basin is a form backend for static sites with spam filtering and integrations. FormSubmit is a headless form backend: you keep full control of your form's HTML and design, and every plan — including Free — includes spam protection, file uploads, webhooks and all integrations.

About Basin

Basin offers form endpoints for static websites with spam filtering, notifications and integrations.

What FormSubmit does differently

  • A public, no-login visual form generator with exports for React, Next.js, Vue, Svelte, Astro, WordPress, Webflow and Framer.
  • Hosted form pages at formsubmit.app/to/{id} built from the same builder.
  • Direct browser uploads for large files, stored privately with signed links.
  • Google Sheets with drive.file scope only.

Pricing

FormSubmit has four plans: Free (1 form, 50 submissions/month), Starter at $5/month (2 forms, 1,000 submissions), Pro at $15/month (10 forms, 5,000 submissions, no branding) and Business at $50/month (unlimited forms, 10,000 submissions). Yearly billing gives two months free. See pricing for details. For Basin's current pricing, visit their website.

When to choose Basin

You prefer Basin's interface or specific features, or your existing sites are already connected to it.

When to choose FormSubmit

  • You want your form to look exactly like the rest of your site.
  • You want integrations, captcha and spam protection without upgrading.
  • You care about privacy details: hashed IPs, encrypted secrets, private files, minimal Google permissions and configurable retention.
  • You build many sites (agency, freelancer) and want one dashboard for all of them.

How to switch

  1. Create a FormSubmit form.
  2. Replace the form's action URL (or your fetch URL) with your FormSubmit endpoint.
  3. Keep your field names — emails and exports will look the same.
  4. Recreate integrations in the form's Integrations tab and send a test.

Frequently asked questions

Is FormSubmit a Basin alternative?

Yes. FormSubmit covers the same core job — receiving website form submissions and delivering them to email and other tools — with every integration and spam protection included on every plan.

How hard is it to switch from Basin?

For HTML forms it usually means changing one attribute: the form's action URL. Field names stay the same, so emails and integrations keep working. JavaScript forms change one fetch URL.

Is this comparison up to date?

We review it periodically, but other products change. Always check Basin's own website for current features and pricing.
