I've been using it for a couple months now. If your job involves any meaningful amount of HTTP-related work, it's worth a lot more than $20. If $20 is too much, you're badly underpaid. Even colleagues of mine in Taiwan, who make a fraction what US-based developers do, bought it as soon as they tried it.

You can use the JetBrains tools which have a plugin for HTTP/Rest api testing. Should work with their free java edition. http://www.jetbrains.com/idea/webhelp/rest-client-tool-windo...

A $2 application that I found before I knew about this one is GraphicalHTTPClient (available in the app store). Not as feature rich, but I've really found it handy

It may be $20, but it's a fair bit more robust (and, subjectively, better designed).

Some additional features include code generation (handy for this crufty-type code... especially in Objective-C) and dynamic values (you can pull values out of prior requests to craft more dynamic requests).

+1 for Postman in Chrome. Keeps an excellent history and allows for grouping requests against different "environments" among other nice-ities.

Same here, I'm using Advanced REST client and very happy with it. Plus it is indeed advanced and have many features with Paw in common. (https://chrome.google.com/webstore/detail/advanced-rest-clie...)

+1 to Advanced REST. I use to use that, but these days I use postman https://chrome.google.com/webstore/detail/postman-rest-clien...

+1 for Advanced Rest Client. Even saves my request groups to google drive

Since Postman runs as a separate app outside the browser window, it's essentially a cross-platform desktop app.
