As of 27 October 2026.

The table: Antisy and Friendly Captcha

Antisy and Friendly Captcha, point by point
Criterion	Antisy	Friendly Captcha
Company and legal framework	Antisy Sàrl, a Swiss company entered in the Geneva commercial register. The API and the dashboard (in French) are hosted at Infomaniak, in Geneva, and have been in service since 27 October 2026.	Friendly Captcha GmbH, a German company according to the presentation of the service by its publisher. By default, the widget talks to a global service, served from around the world, whose request may therefore be served outside the EU; a dedicated endpoint, located in Germany, is an option reserved for the Advanced and Enterprise plans. [2] [3]
What the visitor sees	Nothing: no checkbox and no puzzle. The visitor’s browser only does a short computation in the background.	The visitor’s device solves a cryptographic puzzle in the background, with no image task: the documentation says that a single click is the only interaction required. The widget mode is set per application: one click, zero clicks, or “smart” (the default), where the widget decides from the signals of the session whether a click is needed. [1] [4]
Cookies and storage	Neither the verification script nor the API sets a cookie, and the script writes nothing to the browser’s storage. The data the script measures and the data the server reads are listed, with their retention periods, on the home page and in the frequently asked questions.	The publisher states that the service works without HTTP cookies and without tracking the user. [1] [7]
Integration	A `<script>` tag in the page; on submission, the script puts a short token in the hidden field `antisy-token`; your server sends it to `POST /v1/siteverify` with its secret and reads `allow` or `deny`.	A script of the kit `@friendlycaptcha/sdk` and a `frc-captcha` container; the token arrives in the field `frc-captcha-response`. The server sends `response` by `POST https://global.frcapi.com/api/v2/captcha/siteverify`, with its API key in the header `X-API-Key`. [5] [6]
Public prices	Free: CHF 0, 2,500 checks per month and 1 site, no credit card. Standard, Pro and Enterprise: on quote. Access is by waiting list; nothing is paid online.	Free plan for non-commercial sites: 1 domain, 1,000 requests per month. Commercial plans: Starter €9 per month (1 domain, 1,000 requests per month), Growth €39 per month (5 domains, 5,000 requests per month), Advanced €200 per month (50 domains, 50,000 requests per month), Enterprise on contact. A free trial of 30 days is offered. The pricing pages are not dated. [8] [9]
