FormSubmit
Turn any HTML form into a working backend — just point the action attribute to FormSubmit and receive submissions via email. No server, no code, no registration.
Use Cases
Free Tier
Unlimited forms, unlimited submissions, file uploads, webhooks, no registration required
How to Maximize the Free Tier
FormSubmit is the simplest form backend available — no account needed, just point your HTML form's action URL to their endpoint. Enable reCAPTCHA to prevent spam without user friction. Use the _webhook hidden field to also send submissions to a serverless function or Zapier for automation. The API gives you 5 daily access calls to retrieve archived submissions — enough for periodic backups but not real-time queries. For anything needing a dashboard, pair with a spreadsheet via Zapier.
Getting Started
Add form action='https://formsubmit.co/[email protected]' → submit once to confirm email → start receiving submissions instantly. No account creation needed.
Pros
- Zero setup: No registration, no API keys — just change the form action URL and submissions arrive in your inbox
- Unlimited everything: No limits on forms, submissions, or file uploads on the free tier — completely unrestricted usage
- Developer features: Webhooks, AJAX submissions, hidden fields, auto-response emails, and spam filtering built in
Cons
- Email only: Submissions arrive as emails — no built-in dashboard, analytics, or submission management UI
- No database: No persistent storage — submissions are emailed and archived for 30 days via API only
- Spam risk: Without reCAPTCHA enabled, forms can attract spam submissions that flood your inbox
