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

> ⚠️ **DEPRECATED**  
> This package (`@trustcaptcha/trustcaptcha-react@<2.0.0`) has been renamed and is now maintained under [`@trustcomponent/trustcaptcha-react`](https://www.npmjs.com/package/@trustcomponent/trustcaptcha-react) (version 2.0.0 or above). Please update your dependencies!


## 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](https://www.trustcomponent.com/en/products/captcha) for technical details and the security concept.


## Get started

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.
