  • Cross platform: Rollbar.js supports both server-side and client-side Javascript, including frameworks such as React, Angular, Express, Next.js and more.
  • Telemetry: The telemetry timeline provides a list of “breadcrumbs” events that can help developers understand and fix problems in their client-side javascript. Learn more about telemetry.
  • Automatic error grouping: Rollbar aggregates Occurrences caused by the same error into Items that represent application issues. Learn more about reducing log noise.
