Protect websites and apps against bots and spam with a privacy-first, EU-hosted CAPTCHA solution.

What is TrustCaptcha?

TrustCaptcha combines proof-of-work, an AI bot-score and custom security rules to stop automated bot abuse — without image marking or puzzles

Key perks:

• Privacy-friendly & GDPR-compliant – data processed exclusively in Europe
• No visual challenges – users never label images or solve quizzes
• Fully themable widget – matches any brand and design and improves your user flow
• Conversion-safe – near-zero user drop-off compared to legacy CAPTCHAs

Read the full TrustCaptcha product overview for technical details and the security concept.

Get started

1. Create an account: sign up / sign in.
2. Choose a CAPTCHA: pick an existing one or create a new one.
3. Embed the widget: implement the TrustCaptcha widget into your website or app.
4. Validate result: validate the CAPTCHA verification result in your backend.

// Retrieving the verification result
let verificationResult = await CaptchaManager.getVerificationResult("<your_secret_key>", verificationToken);

// Do something with the verification result
if (!verificationResult.verificationPassed || verificationResult.score > 0.5) {
    console.log("Verification failed, or bot score is higher than 0.5 – this could indicate a bot.");
}

Installing the library

composer require trustcaptcha/trustcaptcha-php

Fetching and handling the result

// Retrieving the verification result
$verificationResult = null;

} catch (Exception $e) {
  // Fetch verification result failed - handle error
}
