Astro is designed to generate fast, lightweight static sites. By default, it outputs static HTML with no backend runtime. This makes it ideal for blogs, documentation, landing pages, and marketing sites. However, it also means Astro cannot process form submissions on its own.

Many developers assume they need serverless functions to handle contact forms in Astro. In reality, you can avoid serverless entirely by using a backendless form service like Fabform. With a single endpoint, you can add a fully functional contact form to any Astro site without writing backend code.

Why Astro does not need serverless functions for forms

Astro’s static output means:

• no server‑side processing
• no built‑in email sending
• no backend storage
• no form handling

A traditional HTML form will not work without a backend to receive the submission.

Fabform solves this by providing:

• a secure form endpoint
• spam protection
• email, Slack, and webhook notifications
• a submission dashboard
• CSV export
• GDPR‑friendly storage

Your Astro site stays static.
Your form becomes fully functional.

2. Create a free account

4. Copy your unique form endpoint:

Step 2 — Create a contact page in Astro

Create a new file:

src/pages/contact.astro

Add the following markup:

---
title: "Contact"
---

<h1>Contact</h1>

<form action="https://fabform.io/f/your-form-id" method="POST">
  <label>
    Name
    <input type="text" name="name" required />
  </label>

  <label>
    Email
    <input type="email" name="email" required />
  </label>

  <label>
    Message
    <textarea name="message" required></textarea>
  </label>

  <button type="submit">Send Message</button>
</form>

This form works immediately.
No JavaScript.
No serverless functions.
No backend code.

---

Step 3 — Style your form

Astro supports any CSS approach.
Here is a simple example using a <style> block:

<style>
  form {
    max-width: 500px;
    margin: 2rem 0;
    display: flex;
    flex-direction: column;
    gap: 1rem;
  }

  input, textarea {
    padding: 0.75rem;
    border: 1px solid #ccc;
    border-radius: 6px;
  }

  button {
    padding: 0.75rem;
    background: #000;
    color: #fff;
    border: none;
    border-radius: 6px;
    cursor: pointer;
  }
</style>

---

Step 4 — Test your form

Start your local server:

npm run dev

Visit:

http://localhost:4321/contact

Submit a test message.
You will see it appear instantly in your Fabform dashboard.

---

Step 5 — Deploy your Astro site

Astro can be deployed to:

• Netlify
• Vercel
• Cloudflare Pages
• GitHub Pages
• Any static host

Step 6 — Add spam protection

Fabform includes built‑in spam filtering, but you can add an optional honeypot field:

<input type="text" name="website" style="display:none" tabindex="-1" autocomplete="off" />

Bots fill this field.
Humans do not.
Fabform ignores submissions that include it.

---

Troubleshooting

Form not submitting

Verify your action attribute:

https://fabform.io/f/your-form-id

Not receiving notifications

Check your Fabform notification settings.
