Trustcaptcha is a user-friendly captcha protection tool developed in Germany that protects websites from bot attacks and spam in a GDPR-compliant and barrier-free manner. Unlike other captchas, Trustcaptcha not only slows down unwanted actions, but also provides a trust score for each request similar to google reCAPTCHA. In addition, further security levels can be optionally activated. This ensures robust security while prioritising the user experience through automatic activation without the need of user intervention. Unless preferred, no picture puzzles or user tasks are required and it only takes seconds. There are many more options, including customising the design, settings and language, as well as the ability to hide the branding or captcha completely if required. The integration is simplified with a documentation and libraries for a variety of programming languages. You can choose between fixed prices and pay-per-use. With the pay-per-use model, you can maximise cost efficiency as the cost is directly related to the number of requests you receive, so you only pay for what you actually need.
