About Altcha

ALTCHA is a privacy-focused, open-source CAPTCHA solution that uses proof-of-work challenges to verify users without tracking or cookies. It provides a lightweight alternative to traditional CAPTCHA services.

Usage

Altcha uses an endpoint prop instead of sitekey to specify the challenge URL endpoint for the CAPTCHA service.

import { Altcha } from "@better-captcha/react/provider/altcha";

<Altcha endpoint="https://example.com/api/v1/challenge" options={{}} />

import { component$ } from "@builder.io/qwik";
import { Altcha } from "@better-captcha/qwik/provider/altcha";

export default component$(() => (
  <Altcha endpoint="https://example.com/api/v1/challenge" options={{}} />
));

import { Altcha } from "@better-captcha/solidjs/provider/altcha";

<Altcha endpoint="https://example.com/api/v1/challenge" options={{}} />
