Top 5 Linux Command-Line HTTP Clients and How to Use Them

Linux offers a variety of robust command-line HTTP clients that simplify interacting with web services directly from the terminal. Below are five of the most popular tools, each accompanied by practical usage examples.

cURL

cURL is a versatile command-line utility supporting many protocols such as HTTP, HTTPS, and FTP. Common use cases include sending simple GET requests and posting data from files.

Send a GET request and output the response: curl https://api.example.com Send a POST request with the request body read from a file:

curl -X POST -d @data.json https://api.example.com

HTTPie

HTTPie provides a more user‑friendly syntax and colored output, making it easier to work with APIs compared to cURL.

Send a GET request: http https://api.example.com Send a POST request with JSON parameters:

http POST https://api.example.com Content-Type:application/json name="John" age:=30

Wget

Wget is a non‑interactive downloader that can also be used for basic HTTP requests.

Download a file: wget https://example.com/file.zip Recursively mirror an entire website:

wget --mirror --no-parent https://example.com

HTTPie-go

HTTPie-go is the Go implementation of HTTPie, offering faster performance while retaining a similar syntax.

Send a GET request: http-go get https://api.example.com Send a POST request with JSON data:

http-go post https://api.example.com Content-Type:application/json name=John age=30

Wuzz

Wuzz is an interactive HTTP client featuring auto‑completion and real‑time preview, useful for building and testing requests on the fly.

Launch the interactive interface: wuzz Send a request using a predefined template: wuzz -template post.json These command-line HTTP tools cover a wide range of scenarios, from quick one‑off requests to complex API testing, helping developers and operators work efficiently within a Linux terminal.
