Is RestMan safe?

This extension sends HTTP and HTTPS REST API requests from a browser interface.

It lets users enter a URL, choose methods such as GET, POST, PUT, DELETE, PATCH, and OPTIONS, and send the request from the extension window. It shows response details such as time, size, type, content, headers, highlighted output, and an HTML preview when available. It also supports custom request headers, raw or form body data, request history, themes, layout options, and sharing requests.
