If you are not yet sure which pricing plan to choose, no problem! The plan can be extended at any time.

If you want to start directly with a paid CAPTCHA, all you have to do is add your billing details and optionally a payment method and you're ready to go.30-day trail periodIf you opt for the 30-day trial period, you can test CAPTCHA for 30 days risk-free.

Frequently Asked Questions

What is a Vue CAPTCHA?

A Vue CAPTCHA is a small component you drop into a Vue 2 or Vue 3 application to confirm a visitor is human before a form is submitted. It loads an invisible widget that runs client-side logic and returns a signed token you can verify on the server. TrustCaptcha’s Vue integration, for example, starts automatically and needs no puzzle clicks, so your UX stays smooth.

What is the best Vue CAPTCHA?

The best Vue CAPTCHA balances security, privacy and user experience rather than only slowing bots down. TrustCaptcha pairs adaptive proof-of-work with an AI-based bot score and granular security rules, blocking up to 99.9 % of automated abuse—five times more than pure proof-of-work alternatives. It is hosted entirely in EU data centres, ships ready-made Vue hooks and can be fully white-labelled to match your brand. Those combined advantages make it the first choice for European Vue applications that need both GDPR compliance and top-tier protection.

How does a Vue CAPTCHA work?

When the TrustCaptcha Vue component mounts, it starts a dynamically scaled proof-of-work puzzle in the browser while sending behavioural signals to an AI model that returns a bot-probability score. Once the combined score meets your configured threshold, the component emits a verification token which you forward to your backend and validate with one REST call. All traffic is encrypted via TLS and no cookies are stored, keeping sessions private and stateless.

Do I need a Vue CAPTCHA?

Any public form, login or comment endpoint in a Vue SPA invites credential stuffing, spam and scraping. Bots are now able to solve traditional image CAPTCHAs with first-try accuracy above 94 %, making stronger multilayered methods essential. TrustCaptcha’s adaptive proof-of-work and bot score turn those attacks into an unprofitable endeavour without disrupting users. Beyond security, a GDPR-compliant, privacy-first CAPTCHA can also reduce legal risk and signal trustworthiness, factors highlighted in 2025 SEO trend reports.

Is TrustCaptcha GDPR compliant and where is the data hosted?

Yes. TrustCaptcha processes and stores all telemetry exclusively in ISO/IEC 27001-certified data centres inside the European Union, ensuring data never leaves the EU. A Data Processing Agreement and Service-Level Agreement can be executed online from your account dashboard at any time. Because no cookies are set and a minimal-data mode is available, only a short note in your privacy policy is usually required.

Can I customise the look and feel of TrustCaptcha?

Every visual element is configurable: choose light, dark or auto themes, override colours with CSS variables, and localise the copy into more than 35 languages. You can hide the brand badge, switch to an invisible mode or insert your own privacy-policy link for white-label deployments. All options are available through the dashboard or as props on the Vue component, so designers can match any style guide without touching backend settings.

What impact does TrustCaptcha have on performance and accessibility?

The widget adds only a few kilobytes of JavaScript and no heavy images, loading up to three times faster than puzzle-based CAPTCHAs. Because it solves itself automatically, conversion rates have risen by 183 % in A/B tests compared with click-required alternatives. The challenge is fully keyboard-accessible and WCAG 2.2 compliant, making it usable with screen readers out of the box. Faster, more accessible pages also align with Google’s people-first content and page experience guidance for 2025.
