WMS Inspector is a Firefox add-on with tools for working with Web Map Services (WMS). It can be especially useful when working with JavaScript mapping libraries like OpenLayers or MapBender or setting up WMS services with servers like MapServer, GeoServer, or deegree. Its main features include structured loading of all WMS requests in the current page and its parameters, sorted by service or type, individual WMS request (images or errors) visualization on a lateral pane, the ability to copy services, requests, or parameters to the clipboard, direct editing of request parameter values, and output of GetCapabilities requests as an HTML report or the original file.
