Record active tab network traffic, export HAR as ZIP, view and replay GraphQL requests Network HAR Recorder captures network traffic from the active browser tab and saves it as a HAR file inside a ZIP archive. Open the file in the built-in viewer to inspect requests, filter GraphQL calls, copy Postman-style URLs, and optionally replay GraphQL requests with OAuth credentials you configure in Settings. Features • Start/Stop recording from the popup — full network log with request/response bodies • Export as ZIP (network-*.zip with HAR inside) • Built-in HAR viewer: table, search filter, GraphQL-only mode • GraphQL panels: URL, request body, variables, headers, response • Send — replay a selected GraphQL request using your Token URL, Client ID, login, and password (OAuth password grant) • Custom Send headers (default: x-login with your login) • Optional GraphQL URL rewrite rules for multi-environment APIs Privacy Recording and settings stay on your device. Send transmits credentials only to endpoints you configure, when you click Send. No analytics or remote servers operated by the developer.
