RudderStack

RudderStack Assistant - Debug your RudderStack JavaScript SDK (events, destinations, plugins, user state) in Chrome and Firefox

Instantly see what your RudderStack instrumentation is actually doing. The moment you open a page running the RudderStack JS SDK, Assistant detects it and gives you a live, read-only view of every event, destination, and piece of SDK state — all locally in your browser. Nothing is ever sent off your device. WHAT YOU GET ✓ Automatic SDK detection — version, write key, data-plane URL, install type ✓ Live event stream — every track/identify/page/group event with full, formatted payloads ✓ Delivery status — HTTP status for each event, including sendBeacon traffic ✓ Destinations & plugins — which device-mode destinations and plugins loaded, failed, or were filtered, with error details ✓ User & session state — identity, traits, and where they're stored (localStorage, cookies, memory…) ✓ Preserve log across navigations — keep event history through multi-page flows ✓ One-click export — copy or download full debug data for bug reports and support ✓ Optional SDK injection — drop a test SDK onto any page to trial tracking before you ship PRIVACY All inspection is local. Captured events stay in the extension's memory for the tab you're debugging and are dropped when the tab closes. The extension transmits no data off-device. Built for developers, analytics engineers, and QA validating RudderStack on Chrome & Firefox.
