The free form backend for HTML, Next.js, React & Astro

Yes — 500 form submissions per month, 2 forms, honeypot spam filtering, and the submissions dashboard are included on the free plan. No credit card required, ever. Starter is $1/month when you want exports, webhooks, and integrations.

We give you 500 free submissions/month (vs Formspree's 50, Basin's 50, Web3Forms' 250), a $1/month Starter plan with paid features, and Pro at $5/mo for 5,000 submissions. The 3-Year plan ($59 every 3 years for 15,000/mo over 36 months) still has no competitor equivalent.

Drop our endpoint into your form's action attribute and add a hidden input with your access key. That's it — works on any static site (Next.js, Astro, Hugo, Gatsby, GitHub Pages, Cloudflare Pages, Netlify, Vercel). No backend code, no PHP, no SDK to install.

Yes. Our form backend API works identically across every framework — HTML, React, Next.js, Vue, Nuxt, Svelte, SvelteKit, Astro, Hugo, Gatsby, Remix. The integration is just a POST request, so anywhere you can submit a form, you can use splitforms.com.

Yes — Webflow's custom form action setting, Framer's form integration, Carrd's form-to-URL setting, and WordPress (no plugin required) all work. Just point the form action at splitforms.com/api/submit and add the hidden access_key input.

We use a hidden honeypot field. Bots fill it; humans don't see it. Triggered submissions are stored and silently flagged as spam in your dashboard so you can audit the false-positive rate. Real submissions stay in your dashboard, and owner notification emails work on every plan. No CAPTCHA — your visitors stay frictionless.

Yes, on Starter ($1/month) and above. Paste a Slack incoming-webhook URL or Discord webhook URL and we auto-format for that destination, or send raw signed JSON to Zapier, n8n, your own server, or Google Sheets integrations.

Submissions live in Supabase Postgres with row-level security — only you can read your own rows, even we can't read them via the API. We never share, sell, or train models on submissions. EU data residency is on the roadmap.

Yes, within your plan's form limit. Free includes 2 forms, Starter includes 10 forms, and Pro plus 3-Year are the better fit for agencies that need unlimited client forms.

File uploads work through the Storage integration. Use multipart/form-data, connect Storage in the dashboard, and splitforms accepts up to 5 files per submission at 10 MB each. Text-only forms work without any storage setup.

Swap the form's action URL to https://splitforms.com/api/submit and replace the access key. Your existing field names work as-is — name, email, message, etc. Migration usually takes under five minutes per form. We have step-by-step guides for each competitor.

We're early — splitforms.com is in v0 launch. Today the API runs on Vercel + Supabase (multi-region edge + Postgres). A formal SLA with credits will land alongside the Pro plan. Real-time uptime status will publish at status.splitforms.com once we're past launch.
