About ReqBin Online Curl Client

ReqBin Online Curl Client lets you run Curl online, directly in the browser. Paste the command you would run in a shell, press Run, and see the status code, the timings and the response body. No browser plug-ins and nothing installed on your computer.

ReqBin Online Curl Client is a Curl development environment in your browser. It understands the common Curl options: -X for the request method, -H for headers and -d for the request body. Basic authentication (-u), the user agent (-A) and cookies (--cookie) work too. The command you type here is the same one you would type in a terminal.

  • Test APIs, websites, and web services online.
  • Post requests directly from your browser without the need for a dedicated desktop application or browser plugin.
  • Validate server responses in JSON, XML, and HTML format, and ensure that the data you receive is in the expected format and error-free.
  • Generate PHP, Python, JavaScript/AJAX, Node.js, Java, C#/.NET and Curl/Bash code snippets from your Curl requests and integrate these snippets into your projects and test, saving valuable development time.
  • Share your Curl requests online with colleagues or documentation, collaborate with other developers, get feedback, and work together to improve API testing and development.
  • Safe: Curl commands run on the ReqBin server, so nothing is installed on your computer and nothing on your disk is touched. All data is transmitted over a secure SSL channel.
  • Live Curl Examples: learning Curl has never been easier with our extensive collection of live Curl examples. Run the examples online with ReqBin Online Curl Client for hands-on experience with Curl.

ReqBin's online Curl client supports only a specific set of Curl commands for interacting with the HTTP/s protocol. The command-line options related to the file operations are ignored for security reasons.

What is Curl?

Curl stands for client URL. It is a free command-line tool that transfers data to and from a server using URL syntax, and it ships preinstalled with Windows 10 and later, with macOS, and with most Linux distributions. Curl speaks more than 25 protocols — HTTP, HTTPS, FTP, FTPS, SMTP, IMAP and SMB among them — and handles TLS, redirects, cookies and authentication.

The Curl command is the standard way to write down an API call in documentation: one line anyone can copy and run. Developers embed the same engine in their own programs through the libcurl library, available for C/C++, Java, PHP and Python. ReqBin runs those commands without a local Curl installation.

How to Run Curl Commands Online?

With ReqBin Online Curl Client, you can run Curl commands directly from your browser. No desktop apps or browser plugins are required. Just enter the Curl command and click on Run. The built-in Curl command syntax Highlighter will check the syntax of the Curl commands and highlight possible errors while you are typing it in the ReqBin Curl command executor.

What Is an Online Curl Tool?

An online Curl tool is a web page that runs Curl commands for you, so you do not have to install Curl or open a terminal. You paste a command, ReqBin sends the request from its own server, and you get back the status code, the response headers, the timings and the body.

Test APIs with Online Curl Client

ReqBin has been running Curl commands in the browser since 2022. More than a million developers have used it since. You can test API endpoints by running Curl commands in your browser and reading the server response. ReqBin Online Curl Client provides millisecond accurate timings, including DNS Resolution, Connection, TLS Setup, and data transfer times. Built-in JSON and XML formatters will automatically format and validate the returned JSON and XML strings and highlight any errors in your data.

Convert Curl Commands to HTTP Requests

Paste a Curl command and ReqBin fills in the method, URL, headers and body of a plain HTTP request. The same command converts to PHP, Python, JavaScript/AJAX, Node.js, Java, C#/.NET or Curl/Bash code.
