Django Simple Captcha

Django Simple Captcha is an extremely simple, yet highly customizable Django application to add captcha images to any Django form.



  • Very simple to setup and deploy, yet very configurable
  • Can use custom challenges (e.g. random chars, simple maths, dictionary word, ...)
  • Custom generators, noise and filter functions alter the look of the generated image
  • Supports text-to-speech audio output of the challenge text, for improved accessibility
  • Ajax refresh


  • Django 1.7+
  • A recent version of Pillow compiled with FreeType support
  • Flite is required for text-to-speech (audio) output, but not mandatory
