Vue.js hCaptcha Component Library

hCaptcha Component Library for Vue.js. Compatible with Vue 2 and 3.


You can install this library via npm with:

  • vue2: npm install @hcaptcha/vue-hcaptcha --save
  • vue3: npm install @hcaptcha/vue3-hcaptcha --save

or via yarn:

  • vue2: yarn add @hcaptcha/vue-hcaptcha
  • vue3: yarn add @hcaptcha/vue3-hcaptcha

or via script tag (Vue must be globally available)

  • vue2
    <script src=""></script>
    <script src=""></script>
  • vue3
    <script src=""></script>
    <script src=""></script>

Basic Usage

  • vue2:

        <vue-hcaptcha sitekey="**Your sitekey here**"></vue-hcaptcha>
      import VueHcaptcha from '@hcaptcha/vue-hcaptcha';
      export default {
        components: { VueHcaptcha }
  • vue3:

        <vue-hcaptcha sitekey="**Your sitekey here**"></vue-hcaptcha>
    <script setup>
      import VueHcaptcha from '@hcaptcha/vue3-hcaptcha';

The component will automatically load the hCaptcha API library and append it to the root component.
