Everything You Need
What happens after the POST
Delivering an email is table stakes. The real work starts when the submission arrives.
NEW
AI replies, drafted before you open the email
Upload your docs, FAQs, or pricing as a knowledge base. When a submission arrives, Static Forms drafts a reply that actually answers the question. Approve it, edit it, or let it send automatically. Pay-as-you-go credits, no extra subscription.

Build the form visually, embed with one tag
Add text, email, number, date, dropdown, checkbox, and file fields from the dashboard. Set per-field validation rules, pick a captcha provider, then paste a single <script> tag on any page. The embed renders your form and posts to the same documented endpoint as every other Static Forms integration.

Comparing Options?
How Static Forms stacks up against the alternatives
Honest, feature-by-feature comparisons against the form backends developers evaluate most.
WordPress plugin available
Moving away from WordPress? Keep your forms working.
Migrating a WordPress site to Astro, Hugo, or a plain static host is straightforward, until you hit the contact form. Static Forms handles that gap: drop in our WordPress plugin on the old site and swap the form action on the new one. Either way, submissions keep flowing.
- Native Elementor Pro action and Contact Form 7 forwarding, no third-party services
- Survives the migration: same endpoint works on WordPress and the static site
- One dashboard for every client site, static or not

FAQ
Frequently asked questions
How quickly can I set up Static Forms?
You can have your first form working in under 60 seconds. Simply register, get your API key, and add it to your form's action URL. No server setup, no complex configuration required.
Is there really a free plan forever?
Yes! Our free plan includes 500 form submissions per month forever. No credit card required, no time limits. It's perfect for personal projects, portfolios, and small websites.
How does CAPTCHA spam protection work?
We integrate with leading CAPTCHA providers to protect your forms. Free users get reCAPTCHA v2 (checkbox). Pro users unlock reCAPTCHA v3 (invisible, score-based), Cloudflare Turnstile (low-friction, privacy-friendly), and Altcha (privacy-first, GDPR-friendly - no user tracking). Plus, honeypot fields catch simple bots automatically.
Can I use this with any website platform?
Yes! Static Forms works with any platform that can create HTML forms: React, Vue, Angular, Jekyll, Hugo, Gatsby, WordPress, Webflow, Squarespace, and any static site generator. No plugins required.
How do I add a contact form to a Jekyll or Hugo site?
Drop a standard HTML <form> into your Markdown or layout, set the action to our submit endpoint, and include your API key as a hidden input. Because there is no JavaScript requirement, it works inside any Jekyll, Hugo, Eleventy, or Astro template without extra plugins.
Does Static Forms work with Next.js and React?
Yes. Point any React form — Next.js App Router, Pages Router, Vite + React, or Remix — at our API. You can submit with plain <form action> for progressive enhancement, or use fetch/Server Actions if you prefer full control over the client-side flow.
Do you support file uploads and attachments?
Pro and Agency plans support file uploads up to 4.5MB per submission. Attach a standard <input type="file"> with multipart/form-data and uploaded files are forwarded to your email and stored in the dashboard for download.
What happens if I exceed my plan limits?
Form submissions will pause until you upgrade or your monthly limit resets. We'll send you alerts at 75% and 90% usage so you can take action. Upgrading instantly restores service.
Do you store my form data?
With Pro plans, you can optionally enable form data storage to view and manage all submissions in your dashboard. Free plans forward submissions to your email only. All data is encrypted at rest and in transit.
Is Static Forms GDPR compliant?
Yes! We're fully GDPR compliant with data export/deletion on request, consent tracking, IP anonymization, and a Data Processing Agreement (DPA) for business customers. We also offer privacy-friendly CAPTCHA options including Cloudflare Turnstile and Altcha for teams that want alternatives to Google reCAPTCHA.
What's included in the Pro plan?
Everything you need: 25,000 emails/month, advanced CAPTCHA (reCAPTCHA v3 invisible, Cloudflare Turnstile, and Altcha privacy-first), file uploads (4.5MB), form data storage & dashboard, webhook integrations, auto-responders, child account management, CC emails, domain restriction, custom email domain, remove branding, and priority support.
Can I cancel anytime?
Yes, you can cancel your subscription with one click, no questions asked. No contracts, no cancellation fees. Your account stays active until the end of your billing period, then downgrades to our free plan.
Do you offer refunds?
Absolutely! We offer a 30-day money-back guarantee on all paid plans. If you're not satisfied for any reason, contact us for a full refund.
