Free contact form builders for your website
Every business website needs a contact form. These free builders let you embed professional contact forms on WordPress, Squarespace, Webflow, or any HTML site — without paying for a plugin or SaaS subscription.
What makes a good free contact form builder
Contact forms seem simple, but the free tier needs to cover more than name and email fields:
- Embed options: iframe, JavaScript embed, or direct link
- Email notifications: instant alerts when someone submits
- Spam protection: CAPTCHA or honeypot on free
- Mobile responsive: forms must work on phones
- Branding: how visible the builder badge is

2. Tally — unlimited contact form submissions
Tally also offers unlimited contact form responses on free — ideal alongside forms.app for high-traffic sites. Embed as inline iframe or popup. Clean default styling works on minimal sites; customization is more limited than forms.app. See the Tally review.
3. Fillout — modern embed for marketing sites
Fillout produces polished embeds that match contemporary website design. 1,000 free responses/month suits most small business contact pages. Integrates with Notion, Airtable, and Slack for routing inquiries to your team. More in our Fillout review.
4. Google Forms — quick and free, limited polish
Google Forms embeds via iframe but looks unmistakably like Google — fine for personal sites, less ideal for customer-facing businesses. Unlimited responses and Sheets sync are the main advantages. No built-in spam protection. See the Google Forms review.
5. Jotform — feature-rich but capped
Jotform's contact form widgets include CAPTCHA, file uploads, and thousands of templates. Free tier limits you to 5 forms and 100 submissions/month — enough for low-traffic sites testing the platform. Full details in our Jotform review.
