I was not happy with the current REST clients, that are all either to complicated (soap-ui), integrated inside some other tool (HttpRequester, vscode-restclient, ...) or are to basic (can not save/recall previous requests) so I made my own.
Wanted to share this, maybe someone else finds it useful. And it's really easy to hack: just one html file and one js file.
Why no using telnet ?
because it's nice to have requests remembered so that you don't have to write all the json by hand every time.
