    โค๏ธ Lightweight: Crafted with minimalistic UI design.

    โšก๏ธ Fast: Send requests and get/copy responses in real-time.

    HTTP Methods

    • GET - Requests retrieve resource information
    • POST - The server creates a new entry in a database
    • PUT - Updates an existing resource
    • PATCH - Very similar to PUT but makes a partial update on a resource
    • DELETE - Deletes resource or related component
    • HEAD - Retrieve response headers identical to those of a GET request, but without the response body.
    • CONNECT - Establishes a tunnel to the server identified by the target resource
    • OPTIONS - Describe the communication options for the target resource
    • TRACE - Performs a message loop-back test along the path to the target resource
    • <custom> - Some APIs use custom request methods such as LIST. Type in your custom methods.
