Add Google’s Invisible ReCaptcha to your project. This library
automatically handles ReCaptcha’s events and retrieves the validation token or notifies you to present the challenge if
invisibility is not possible.

Warning ⚠️

Beware that this library only works for Invisible ReCaptcha keys! Make sure to check the Invisible reCAPTCHA option
when creating your API Key.


ReCaptcha is available through CocoaPods and Carthage.
To install it, simply add the following line to your dependencies file:


pod "ReCaptcha"
# or
pod "ReCaptcha/RxSwift"


github "fjcaetano/ReCaptcha"

Carthage will create two different frameworks named ReCaptcha and ReCaptcha_RxSwift, the latter containing the RxSwift
extension for the ReCaptcha framework.


Simply add ReCaptchaKey and ReCaptchaDomain (with a protocol) to your Info.plist and run:

let recaptcha = try? ReCaptcha()

override func viewDidLoad() {

    recaptcha?.configureWebView { [weak self] webview in
        webview.frame = self?.view.bounds ??

func validate() {
    recaptcha?.validate(on: view) { [weak self] (result: ReCaptchaResult) in
        print(try? result.dematerialize())

You can also install the reactive subpod and use it with RxSwift:

recaptcha.rx.validate(on: view)
    .subscribe(onNext: { (token: String) in
        // Do something

Alternte endpoint

If your app has firewall limitations that may be blocking Google’s API, the JS endpoint may be changed on initialization.
It’ll then point to

public enum Endpoint {
    case default, alternate

let recaptcha = try? ReCaptcha(endpoint: .alternate) // Defaults to `default` when unset

Help Wanted

Do you love ReCaptcha and work actively on apps that use it? We’d love if you could help us keep improving it!
