Introduction

An in-app dev-tools panel for React apps. Captures HTTP requests, Redux actions, TanStack Query cache events and realtime traffic, and renders them in a dockable panel with cross-source links, diffing, replay and HAR/cURL export.

The entire panel is eliminated from production builds — see Production elimination. To keep it on a staging server, see Enabling Blix in a production build.

Release notes are in CHANGELOG.md.
