TrustCaptcha for Node.js — GDPR-compliant, privacy-first CAPTCHA

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

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

Basic Node.js integration

• Install the dependency

npm i @trustcomponent/trustcaptcha-nodejs@^3.0.0

• Retrieve the verification result

import { TrustCaptcha } from "@trustcomponent/trustcaptcha-nodejs";

// Retrieving the verification result
let verificationResult;
try {
  verificationResult = await TrustCaptcha.getVerificationResult("<your_api_key>", "<verification_token_from_your_client>");
} catch (error) {
  // Fetch verification result failed - handle error
}

• Act on the result

// Act on the verification result
if (!verificationResult.verificationPassed || verificationResult.score > 0.5) {
    console.log("Verification failed or bot score > 0.5 – possible automated request.");
}

Congratulations — you have successfully validated the result of the CAPTCHA!
