JaSON is an open source, lightweight, and easy to use HTTP client. It supports HTTP requests made with most popular HTTP methods (such as GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS).

There are many types of cookies: JaSON can automatically send cookies from Chrome to the website that requires authentication. It allows you to authenticate via your browser as normal and send cookies for requests that match.

JaSON's request history stores request and response body text as a separate history entry. You can search and filter history to quickly find what you're looking for. It's also possible to mark a history entry as a favourite for quick access.

JaSON's dark theme is a great way to make your web app or site look a bit prettier. You can change the colour of the text and background to suit your work environment.
