CAL.COM CLOSES OPEN-SOURCE CODE OVER AI SECURITY RISKS

Cal.com's decision marks a significant departure from open-source principles, driven by concerns that publicly available code can be exploited by AI tools. The company stated the move addresses modern security threats rather than traditional vulnerabilities. The scheduling platform joins a growing list of companies reconsidering open-source strategies in response to AI capabilities. By closing its core repository, Cal.com aims to reduce exposure to automated code analysis and potential exploitation by machine learning-based attackers. While the company remains committed to supporting its existing open-source community, the core infrastructure will no longer be publicly accessible. This decision reflects broader industry tensions between transparency and security in the age of advanced AI tools. The move underscores emerging concerns about how AI systems can identify and weaponize vulnerabilities in publicly shared code at scale—a challenge traditional open-source security models may not adequately address.
