API Network Recorder από Fernando

API Network Recorder is a developer tool for capturing, inspecting, filtering, and exporting API/network traffic directly from Firefox.

Use it to debug API integrations, inspect request and response data, document observed endpoints, and generate exportable API references from real browser traffic.

Features:

• Capture API-like network requests from web pages.
• Inspect request URLs, HTTP methods, status codes, request headers, request bodies, response headers, and response metadata.
• Filter captured records by search text, HTTP method, status group, source, host, and API-only mode.
• Group captured traffic by endpoint.
• Export captured records as JSON.
• Export grouped endpoints as Markdown documentation.
• Export an OpenAPI draft based on observed traffic.
• Pause and continue live updates in the inspector.
• Store captured records locally in the browser.

Firefox uses silent network capture through webRequest. Response bodies may be unavailable when the browser does not expose them through standard extension APIs.

Captured data is stored locally in the browser and is not uploaded to an external server by this extension.
