TianaiCAPTCHA is a Java-based behavioral CAPTCHA library supporting slider, rotation, slide-restore, and text-click CAPTCHA types. It ships as a plain Java library plus a Spring Boot starter for generating and validating image CAPTCHAs in web applications.
Use cases
- add slider captcha to a spring boot login form
- generate and validate image captchas in java
- prevent bot signups with behavioral captcha
- rotate and text-click captcha for java web app
- self-hosted captcha alternative to reCAPTCHA
- integrate captcha with redis-backed expiry in spring
When to choose
- you need a self-hosted, customizable behavioral CAPTCHA in a Java or Spring Boot project
- you want multiple CAPTCHA styles (slider, rotation, click) from one library
- you prefer an open-source alternative to third-party CAPTCHA services
When to avoid
- your stack is not JVM-based
- you need fully managed anti-bot protection with risk scoring like Cloudflare Turnstile or reCAPTCHA enterprise
- you need accessibility-friendly or invisible CAPTCHA only
