A simple to use and integrate captcha plugin for Umbraco Forms which supports hCaptcha, reCaptcha and Cloudflare Turnstile.

Getting started

This package is supported on Umbraco 10+ and Umbraco Forms 10+.

This package has been tested on Umbraco 11 and Umbraco Forms 11, however only LTS versions of Umbraco and Umbraco Forms are officially supported.

Breaking Changes:

V4.0.0 15 February 2023:

Cloudflare Turnstile has been reworked to use a signle javascript file removing umbracoforms.invisible.turnstile.js Cloudflare Turnstile has been reworked to use the cf- prefix instead of g- All javascript has been rewritten to remove jQuery dependency


UmbracoForms.uCaptcha is available from NuGet or as a manual download directly from GitHub.

dotnet add package Our.Umbraco.Forms.uCaptcha


This package adds hCaptcha, reCaptcha or Turnstile to Umbraco Forms, configurable in the appsettings.json.

It has the ability to choose from the traditional checkbox or invisible options.

Getting Started

Before you begin you will need to get your API keys from your preferred provider, you can get these from the links below:




You will need to add the following settings to your appsettings.json

  "uCaptcha": {
    "SiteKey": "YOUR SITE KEY",
    "SecretKey": "YOUR SECRET KEY",
    "Provider": "YOUR CHOSEN PROVIDER"

To select the provider you will need to change the following setting to your appsettings.json


The choices are either hCaptcha or reCaptcha or Turnstile

Required theme changes

You need to ensure you have included @Html.RenderUmbracoFormDependencies() in your site: https://docs.umbraco.com/umbraco-forms/developer/prepping-frontend

Alternatively you can load the packages script dependencies using the method below in your themes Render.cshtml around line 60/61

@if (Model.CurrentPage.JavascriptCommands.Any())
    document.addEventListener("DOMContentLoaded", function() {
        @foreach (var javascriptCommand in Model.CurrentPage.JavascriptCommands)

If you are using the default theme you will need to create a custom theme using the zip found in the documentation here: https://docs.umbraco.com/v/10.x-lts/umbraco-forms/developer/themes

You can change the default theme used by Umbraco in your appsettings.json file

"Forms": {
    "FormDesign": {
      "DefaultTheme": "default",

Reference: https://docs.umbraco.com/v/10.x-lts/umbraco-forms/developer/configuration

Turnstile configuration

The invisible option in the Settings Size dropdown does not do anything when using Cloudflare Turnstile, the invisible mode is controlled by the SiteKey.
