AjPlus Captcha is an open-source behavioral CAPTCHA library providing sliding puzzle and click-word verification challenges with frontend UI components and a Java backend verification service. It ships client implementations for Android, iOS, Flutter, uni-app, ReactNative, Vue, Angular, HTML, and PHP, with a dependency-free Java core extensible via SPI.

Use cases

  • add a sliding puzzle captcha to a login form
  • protect signup and comment forms from bots with click-word verification
  • verify captcha answers server-side in a Java backend
  • embed a captcha in a Flutter or uni-app mobile app
  • integrate human verification into a Vue or Angular web app
  • block automated credential stuffing on a web login

When to choose

  • you need behavioral captchas (slide puzzle, click word) rather than distorted text
  • your stack includes Java on the backend and any of Vue, Angular, Android, iOS, Flutter, or uni-app on the client
  • you want a dependency-free core that can be extended with custom captcha types via SPI
  • you need a self-hosted captcha solution instead of a paid third-party service

When to avoid

  • your backend is not on the JVM and you cannot port the verification logic
  • you prefer fully managed captcha services like reCAPTCHA or hCaptcha with no server code
  • you need accessibility-first or audio-based captcha alternatives
  • you only need simple image-distortion text captchas
