Formboost is a hosted form submission API that lets you connect your HTML forms to a Formboost endpoint and receive submissions instantly, without building your own server, API route, or database.
What is Formboost?
Formboost is a serverless form backend for static sites and frontend frameworks like React, Next.js, Vue, Astro, SvelteKit, or plain HTML. You point your form's action attribute to a unique URL, and Formboost handles secure storage, email notifications, webhook delivery, and AI-powered spam filtering. It runs entirely on the web and works with any stack that can POST form data.
Key Features
Formboost bundles every essential backend need into one drop-in endpoint, from spam screening to chat integrations.
- AI-powered spam protection — Heuristics screen every submission; from the Starter plan an AI model reads ambiguous submissions in your form's own context and scores them 0–100. No CAPTCHA is required.
- One form endpoint, any stack — Point a plain HTML
actionat your endpoint or POST JSON from JavaScript; CORS is handled automatically for all major frameworks. - Email notifications on every submission — Each submission reaches your inbox in seconds with all fields included; set the recipient address and subject line per form.
- Submission dashboard and CSV export — Search and filter by field, date, or spam score, mark items reviewed, and export the full history to CSV.
- Webhooks and a REST API — Forward submissions to any HTTPS endpoint with custom headers, test payloads, and per-attempt delivery records; REST API included on Starter and up.
- Native integrations, no glue code — Deliver directly to Slack, Discord, Telegram, Google Sheets, Zapier, or n8n; the three chat apps are included on the free plan.
- Enterprise reliability — Runs on globally distributed infrastructure with a 99.99% uptime SLA, 15ms average response time, and 100% data encryption.
