### **Features**

❤️ **Lightweight:** Crafted with minimalistic UI design.

⚡️ **Fast:** Send requests and get responses in real time.

- `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.
