Convert any cURL command into various coding languages, such as PHP, Python, Javascript, C, C#, Perl, Java … Curlconverter.com is an open-source utility that automates the translation of cURL commands and HTTP Archive (HAR) files into executable source code for various programming languages, including Python, JavaScript, Go, Rust, and MATLAB.

The platform parses complex request parameters—such as headers, cookies, authentication credentials, and JSON payloads—to generate syntactically accurate code snippets using standard libraries like Requests, Axios, or native fetch. By facilitating the transition between command-line network interactions and programmatic implementation, the service reduces manual coding overhead and minimizes errors during the integration of web-based services into software architectures.

For a quick intro into the cURL usage in your own coding environnent.

In engineering, quality assurance, and science, professionals apply this tool to convert manual debugging sessions into automated system integrations.

Disciplines: Software engineering, API development, DevOps, Web development.

Free alternative to Postman code generator, Insomnia.

cURL converter compared with Postman code generator and Insomnia
cURL converter	Postman code generator	Insomnia
Function and input: The tool translates a curl command written in Bash syntax into source code. The project page does not list HAR as an input; HAR appears only as an output format.	Function and input: Postman generates code from a request that is already open in the app. A cURL command can first be imported through Import or pasted into the request URL field.	Function and input: Insomnia converts a pasted cURL command into a request through its Import function, then generates client code from that request. Code generation applies to HTTP and event stream requests.
Output languages: The project lists over 30 outputs, including C, C#, Go, Java, JavaScript, Python, PHP, Ruby, Rust, Swift and R, plus Ansible, HAR, HTTP, HTTPie, JSON and Wget. Several languages come in library variants such as python-http and node-axios.	Output languages: Postman lists C#, cURL, Dart, Go, raw HTTP, Java, JavaScript, Kotlin, C, NodeJS, Objective-C, OCaml, PHP, Postman CLI, PowerShell, Python, R, Ruby, Rust, Shell and Swift, often with several client libraries each.	Output languages: The documentation says the user can choose from a variety of languages but does not name them on the page consulted.
Openness and licence: The code is published under the MIT licence.
Installation and self-hosting: It can be used as a web page, as a Node.js library, or as a command line tool installed with npm install --global curlconverter, which behaves like curl but prints code instead of sending the request. Self-hosting in a browser requires serving two WASM files, tree-sitter.wasm and tree-sitter-bash.wasm.	Installation and self-hosting: Code generation is done inside the Postman application, in the Code panel of the request. Postman also documents a separate browser converter for pasted cURL commands that states no account is required.	Installation and self-hosting: Used inside the Insomnia application: the request is created by importing cURL, then the Generate Client Code option is used.
