Pie

Jakub Roztocil profile from Pie
Pie Logo

Pie enables developers to produce and consume APIs more effectively to build the tools, apps and technologies we rely on.

Whether it's exploring an API, testing it or using it to pull data, API users often go beyond developers to product managers, data analysts and others. As the world increasingly becomes API driven, interacting with and collaborating on APIs should be as easy at working with a website or mobile app.

HTTPie was founded by Jakub Roztocil who previously founded the popular open-source project of the same name.
