In light of Google’s announcement that all reCAPTCHA keys must be migrated to a Google Cloud (with fees of $8 per 100k validations) by the end of 2025, website owners are reassessing their security measures. This development may lead to increased costs and necessitates action to ensure protection against bots. Consequently, lets explore alternative CAPTCHA solutions.

Why would you want to switch?
Aside from the fact you now will have to pay for the service, reCAPTCHA, has numerous problems and widely faced criticisms:
User Experience Challenges: Many users find reCAPTCHA tasks cumbersome, especially when multiple image selections are required. This can be particularly frustrating for individuals on mobile networks or those not logged into Google accounts. The last thing you want is to challenge the user to pick a slew of images while in the middle of checkout or account verification.
Privacy and Data Concerns: reCAPTCHA tracks user behavior and collects data, raising concerns about user privacy and potential non-compliance with regulations like GDPR. The system’s reliance on tracking cookies and its promotion of integration with Google services have been points of contention. This is just another way of (hundreds) that Google hovers up user data.
Performance Impact: Implementing reCAPTCHA can introduce additional external calls and load resources, potentially slowing down website performance. This added js bloat can negatively affect page speed, user experience, and ding your core-web-vitals score.
Accessibility Issues: reCAPTCHA poses challenges for users with disabilities, particularly those who are deafblind, as the system is not fully supported for such individuals. This limitation effectively restricts access for these users on pages utilizing the service. But then again, this seems to be true for all the “puzzle” challenges.
Security Limitations: Despite its purpose, reCAPTCHA can be bypassed through methods like CAPTCHA farms, where humans are employed to solve challenges, or advanced machine learning algorithms that automate the solving process.
