SigInspector is a Chrome add-on designed for developers working with Statsig, offering a streamlined way to view and inspect event logs, gate evaluations, and experiment exposures directly within Chrome DevTools. This tool enhances debugging capabilities by presenting real-time data in a clean interface, allowing users to easily confirm that events are firing correctly and verify which gate or experiment variant a user experienced.

The extension simplifies the debugging process by eliminating the need for parsing raw network requests or manually inspecting payloads. With features such as instant visibility of SDK initialization calls and a structured view of SDK activity, SigInspector enables users to quickly identify missing exposures and resolve instrumentation issues. Installation is straightforward, requiring no configuration or Statsig account, and the extension prioritizes user privacy by functioning entirely within the browser without external data transmission.
