TrustCaptcha offers a modern, user-centric approach to CAPTCHA securityโ€”built to protect your site without disrupting your users. Unlike traditional CAPTCHAs, it works silently in the background, with no image puzzles, clicks, or visual interruptions. Verification starts automatically as users begin typing and is typically completed before they finish, ensuring a seamless experience. This reduces friction, lowers bounce rates, and helps you recover lost conversions from frustrated users.

To ensure strong and adaptive protection, TrustCaptcha analyzes every request in real time using a dynamic trust scoring system. Suspicious behavior is filtered out instantly, while legitimate users pass through unnoticed. A lightweight proof-of-work mechanism adds a cost barrier for bots, making large-scale spam or abuse financially unsustainableโ€”without affecting performance for real users. For added security, optional layers like geoblocking or IP filters can be activated as needed.

TrustCaptcha is also fully customizable to match your brand and user flow. You control the language, interface behavior, and designโ€”right down to making the CAPTCHA completely invisible. It supports over 50 languages, works on all devices, and adapts automatically to hardware performance. Integration is fast and developer-friendly, with libraries for all major frameworks and platforms, backed by clear documentation and support.

Pricing is flexible: choose a fixed-rate plan for predictable billing or a scalable pay-per-use model that grows with your traffic. Either way, you get enterprise-level protection with full GDPR compliance and a clear return on investment.

With TrustCaptcha, you reduce spam, block bot abuse, improve conversion rates, and enhance user experienceโ€”all without compromising control, compliance, or speed.

  • Fighting API Bots with Cloudflare's Invisible Turnstile
    I did a lot of work on this many years ago at Google. As the article says, it can work well and be minimally invasive for users (they need to run JS but that's a much lower bar than solving complicated CAPTCHAs). There are several services like Turnstile. I'm an advisor to Ocule [1] which is a similar thing, except it's a standalone service you can use regardless of your serving setup rather than being integrated... - Source: Hacker News / about 2 years ago
