PostHog offers a free, open-source, docker-based deployment, but it has several limitations. For instance, the free version allows only one project and lacks certain advanced features such as Experimentation, Advanced Paths, and Permissions​ In contrast, Zipy.ai provides a more comprehensive solution. Zipy.ai not only includes session replay, product analytics, and error monitoring but also offers features that are seamlessly integrated for better performance and user experience optimization. Unlike PostHog, which may struggle with some recording issues and lacks no-code event tracking, Zipy.ai excels in providing high-quality user session replays, no-code event tracking through its Zipy Labels plugin, and integrated error monitoring. These capabilities allow teams to diagnose and resolve issues quickly, offering a significant advantage over PostHog​.
