Changelog:

2025-06-01 (V1.2.1) by Fraenkiman
  • Fixed: Correct solution in the Brave browser with incognito window outputs incorrect input.
  • In addition to the image captcha, an audio captcha is now also offered if the server supports eSpeak.
  • More robust security/rate limiting mechanisms.
2025-06-01 (V1.2.0) by Fraenkiman
  • More resistant to bots/OCR because the image now uses real 24-bit color with alpha channel.
  • Overall, the CAPTCHA is more difficult to crack using automated text recognition.
  • New invisible field (“honeypot”) blocks more bots.
