Features

❤️ Lightweight: Crafted with minimalistic UI design.

⚡️ 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.
