Code & DevelopmentFreemium

Highlight.io is an open-source session replay, error monitoring, and logging platform that gives full-stack developers complete visibility into what users experience in their applications. It records user sessions with full DOM replay, captures JavaScript errors with source maps, and correlates frontend errors with backend logs—enabling developers to reproduce and debug issues with the full context of what happened. Highlight.io is self-hostable and significantly more affordable than commercial alternatives.
