What Makes Modulis Different?
Hotjar is designed for UX researchers and marketers who want heatmaps and feedback widgets. Modulis is built for engineering, product, and business teams who need full observability alongside user behavior insights.
Hotjar's session replay is focused on UX optimization and doesn't connect to any backend data. Modulis correlates frontend sessions with backend logs, metrics, and traces for complete debugging visibility.
With Hotjar, you need separate tools for every other type of monitoring. Modulis replaces your entire observability stack—APM, logging, analytics, and replay—with a single self-hosted platform.
Hotjar sends all user interaction data to their cloud with limited data residency options. Modulis runs entirely on your infrastructure, giving you full data ownership and compliance control.
Modulis includes LLM analytics, AI agent monitoring, and real-time custom dashboards that Hotjar doesn't offer—making it a comprehensive platform, not just a UX tool.
