A form backend lets you collect submissions from any HTML form without running your own server. You point the form action URL at a service and it handles email, storage, and spam protection.
FormBeam is a simple option focused on indie and frontend developers. You get email notifications, a searchable dashboard, built-in spam filtering, and optional auto-replies. Free plan includes 100 submissions per month.

You build the form yourself (HTML, React, Astro, Webflow, whatever). The backend service receives the POST, stores the data, sends you email, and protects against spam.
It is the opposite of a full form builder. You keep full control of the design.
If none of the above fit, the best choice usually comes down to how many submissions you expect, whether you need integrations now, and how much you care about a real dashboard vs just email.
It depends on your volume and needs. For simple indie or client sites that want email plus a dashboard, FormBeam is a strong option. If you need the absolute highest free tier, Web3Forms is hard to beat. If you are already on Netlify, their built-in forms can be the path of least resistance.
No. Most services (including FormBeam) provide honeypot plus additional filtering. On FormBeam, filtered spam does not count toward your submission limit.
Yes. All the services listed here work with plain HTML forms. Most also support JavaScript/fetch submissions.
Most services either stop accepting submissions or start charging overage. FormBeam continues accepting submissions and bills at $0.018 each.
FormBeam does not support webhooks yet. Formspree, Web3Forms, and Basin all offer webhooks on paid plans.
No. You design the form. FormBeam only handles the backend (receiving, storing, notifying).
