EnglishWhich captcha types are demonstrated on Demo captchas?
Updated
Demo captchas (democaptcha.com) is a demo site that hosts sample forms for several common captcha systems, so you can see how each one looks and behaves before integrating it. Based on the site's own page content, it demonstrates six form types: a regular image captcha, reCAPTCHA 2, hCaptcha, a math captcha, and three Cloudflare Turnstile variants (standard, Explicit, and Invisible).
The captcha types on the site
The homepage lists its demo forms under the heading "Demo captchas" and presents them as a set of test forms. The types shown are:
| Captcha type | What the demo form shows |
|---|---|
| Regular image captcha | A classic distorted-text image challenge |
| reCAPTCHA 2 | Google's checkbox-style "I'm not a robot" widget |
| hCaptcha | The hCaptcha widget as an alternative to reCAPTCHA |
| Math captcha | A challenge that asks the user to solve a simple arithmetic question |
| Turnstile Cloudflare | The standard Turnstile widget |
| Turnstile Cloudflare Explicit | Turnstile in its explicit rendering mode |
| Turnstile Cloudflare Invisible | Turnstile in its invisible mode, with no visible widget |
The page also carries Russian-language labels ("Тестовые формы," "Тестовая форма обычной графической капчи," "Тестовая форма reCAPTCHA 2"), indicating the same set of test forms is described in more than one language.
How to use the demos
Each entry is a live form, so the practical use is straightforward:
- Open democaptcha.com.
- Pick the captcha type you want to inspect.
- Interact with the form the way a real visitor would — solve the image, tick the reCAPTCHA box, answer the math question, or let Turnstile run.
- Observe how the challenge appears and what happens after you complete it.
This is useful when you are choosing a captcha for a site and want to compare the user-facing experience — for example, how much friction a math captcha adds versus an invisible Turnstile check — before committing to one.
What the demos do not tell you
The site is a demo of the front-end forms only. The page content does not include pricing, integration code, server-side verification steps, or documentation for any of the listed providers. If you need those details, go to each provider's own documentation. Treat democaptcha.com as a way to preview and compare the challenge types, not as an integration guide.
