Open source (and self-hosted) session replay tools

Open-source session replay tools provide an alternative to proprietary options like Hotjar and FullStory, offering developers and product teams the ability to record and analyze user interactions on websites and apps. These tools, such as PostHog, OpenReplay, Sentry, UXWizz, UXlens, and Matomo, offer varying features, from session replays and heatmaps to error tracking and product analytics, often with self-hosting capabilities for enhanced data control and privacy. PostHog stands out for its comprehensive integration of analytics, feature flags, and error tracking, making it suitable for startups and product-focused developers, while OpenReplay provides advanced debugging tools and co-browsing capabilities. Sentry integrates session replays with error monitoring for developers, UXWizz offers lightweight analytics for small businesses, UXlens focuses on user interface insights without extensive analytics, and Matomo provides web analytics with session recording as an add-on. These tools cater to different needs, whether for mobile support, self-hosting requirements, or integration with existing monitoring systems, each with unique pricing models ranging from free tiers to one-time license fees.
