JavaScript errors
Every uncaught error your visitors actually hit, grouped and ranked by frequency.
AI insights
JavaScript Errors groups client-side exceptions by message and stack signature, ranks them by how many sessions hit each one, and links straight from an error group into a replay of a session where it occurred — so you can see exactly what the visitor was doing when it broke.
Rank by affected sessions rather than raw count. One broken loop firing five thousand errors in a single session looks alarming and affects one person; a quiet error hitting two percent of all visits is the one costing you money.
