## Overview

Postmann is a browser-based REST client. A user configures an HTTP request in the main workbench, sends it to an API, then inspects the returned response in the workbench. The workbench also exposes editors for variables and request headers, saved request history, notes, and an about panel. The sampled source confirms component wiring and local persistence in several editors; the README documents supported methods and response formats. The request/response relationship is documented, but omitted code prevents detailing its internal dispatch and parsing steps.
