Cloudflare Turnstile for your forms
Add Cloudflare Turnstile to any form, automatically or with your own widget. Available on every plan, including Free.
Formbold now supports Cloudflare Turnstile. Open any form, go to Spam & Security, and choose Automatic or Custom. Both are available on every plan, including Free.
- Automatic Turnstile: nothing to add to your site. After submit, visitors see a short Almost there page, hosted by Formbold, with the Turnstile challenge. See Automatic Turnstile.
- Custom Turnstile: you add a Turnstile widget to your form and save the secret key in Formbold. See Custom Turnstile.
Automatic Turnstile and Automatic reCAPTCHA both use that Almost there page. If your form has file uploads, or it submits with fetch() or Ajax, use Custom Turnstile or Custom reCAPTCHA instead. Otherwise the file can go missing, or your script can get an HTML page instead of the JSON it expects.
The spam protection docs are now split into their own guides: Spam & Security, Automatic reCAPTCHA, Custom reCAPTCHA, Automatic Turnstile, Custom Turnstile and Honeypot Protection. Start from the Spam Protection overview.
