SigInspector - Statsig Event Log & Inspector

View and inspect Statsig event logs, gate evaluations, and experiment exposures directly in Chrome DevTools.

SigInspector adds a dedicated panel to Chrome DevTools that intercepts and displays Statsig JavaScript SDK calls in real time in a clean, filterable interface. What you can see: • Event logs triggered via logEvent • Gate evaluations (checkGate, useGate) • Experiment and layer exposures • SDK initialization calls All activity appears instantly as it happens. Why Install SigInspector? Debugging Statsig instrumentation normally requires: • Parsing raw network requests • Manually inspecting payloads • Adding temporary console.log statements • Guessing which variant or gate a user received SigInspector eliminates that friction. It provides a structured, readable view of SDK activity so you can: • Confirm events are firing correctly • Verify which gate or experiment variant a user saw • Identify missing exposures • Debug instrumentation issues in seconds • No configuration. No Statsig account required. How It Works: • Install the extension • Open Chrome DevTools (⌘⌥I / F12) • Click the SigInspector tab Privacy: SigInspector runs entirely in your browser. It does not collect, store, or transmit data externally.
