We did a quality revamp on snowflake questions for the 2 most popular exams COF-C02 and SOL-C01. We'll be monitoring what you think of it. If all goes well, we add it to the other Snowflake certificates as well. That was the plan, but things are still a bit more manual than ideal. Also, we've added relevant documentation to the answer options (when we could find it). Hope you enjoy, feedback is very welcome! Next up is a known bug: Quiz storing and duplicate quiz questions.

We've added dark theme support! You can now toggle between light and dark modes using the theme toggle button in the header. We're focussing a lot on question quality at the moment, but eye health is also a biggie so therefore it's quickly added. Please let us know if you've got any feedback on it.

We've added a comprehensive disclaimer page to clarify our relationship with certification vendors. CertSafari is not affiliated with, endorsed by, or officially connected to any certification vendor or brand (including Snowflake, Databricks, AWS, Azure, or any other brands we provide practice questions for). We are an independent, unofficial educational resource. Please review our disclaimer page for complete details about our service, limitations, and recommendations for exam preparation.

As you probably would have guessed, this website is vibe-coded to the max. Hence it's the definition of bad practices: duplicate code, hardcoded constants, two databases. We've did a big maintenance trying to clean up this mess. If everything is working well, you shouldn't notice any difference. However, if you experience any buggy behavior or issues, please report them through our feedback form. Your reports help us quickly identify and fix any problems that may have been introduced during this maintenance.

We've added the ability to report questions that have issues! After answering a question, you can now click the "Report" button to flag problems like incorrect answers, outdated information, or other issues. This helps us maintain high-quality questions and continuously improve the learning experience for everyone. Your feedback is invaluable in keeping CertSafari accurate and up-to-date.

We've added the ability to support CertSafari through donations! This helps us cover server costs, maintain the infrastructure, and continue improving the platform. Every contribution, no matter the size, helps keep CertSafari running and free for everyone. You can donate by clicking the "Donate" button in the navigation, footer, or after completing a quiz. Thank you for your support!

We've fixed a bug where only a maximum of 3 quizzes were showing up in the quiz history section. All your quiz history entries should now be visible correctly.

We've replaced Google Analytics with Plausible Analytics, a privacy-first analytics tool that doesn't use cookies or track individual users. We only see aggregate statistics (page views, referrers) - no personal data, no individual tracking, no data sales. The only cookies we use are client-side quiz-progress cookies stored locally in your browser to remember where you left off. Your privacy matters to us - that's the internet as it should be. Learn more in our privacy policy.

We've fixed bugs related to storing quiz history. You can now track multiple quizzes for the same certificate, delete quizzes successfully, and quiz progress will no longer be unexpectedly overwritten or unsaved. Please send us feedback if you encounter any issues.

We've upgraded our server infrastructure to improve reliability and performance. This change addresses the downtime issues we experienced due to limitations with our previous hosting tier. We're committed to providing a stable and uninterrupted experience for all users.
