Highlight.io is an open-source full-stack monitoring platform correlating frontend session replay with backend logs and errors in a single view, helping teams debug issues with full context.
Highlight.io is an open-source full-stack monitoring platform that unifies session replay, error tracking, and logging into a single observability tool for web application development teams. The platform captures frontend session recordings alongside the backend logs and errors generated during that same session, allowing developers to replay exactly what a user experienced at the moment an error occurred — seeing the user's actions in the browser while simultaneously viewing the server-side error trace and log output that corresponded to those actions. This correlation between frontend behavior and backend state collapses the investigation cycle for bugs that involve both client and server components, which is the majority of issues in modern web applications.
