Questions & Answers

As answered by people managing ALTCHA.
  1. What makes ALTCHA unique?

    What makes ALTCHA unique is that it is free, open-source and self-hosted, without external services, does not use cookies nor fingerprinting, does not track users, and is fully compliant with GDPR. Unlike other captcha solutions, ALTCHA does not require users to solve puzzles or captchas and uses a proof-of-work mechanism instead.

  2. Why should a person choose ALTCHA over its competitors?

    Here are some key reasons why a person should choose ALTCHA over its competitors:

    • Privacy compliance - ALTCHA is fully compliant with privacy regulations like GDPR since it does not use cookies, fingerprinting or track users. This is a major advantage over other captcha solutions.
    • Open source and self-hosted - ALTCHA is free, open source software that can be self-hosted without relying on external services. This gives more control and independence to the user.
    • Accessible design - ALTCHA uses a proof-of-work mechanism instead of puzzles or captchas, making it more friendly and accessible for humans. Captchas can be difficult for some users.
    • Machine compatibility - ALTCHA is designed to also work for machines and APIs, making services accessible for bots and automated systems. Other solutions may not be as compatible.
    • Modern approach - ALTCHA represents a privacy-first, inclusive approach to spam protection as opposed to traditional captcha methods. This future-proofs the solution.
    • Effective spam filtering - In addition to proof-of-work, ALTCHA also offers an effective spam filter module to block sophisticated spam attacks. This provides comprehensive protection.

    So in summary, ALTCHA's privacy compliance, open design, accessibility, machine compatibility and modern approach give it clear advantages over competing captcha solutions.
