cURL como alternativa Linux a Postman
Actualizado el
Nuestra opinión
cURL can replace Postman for users who are comfortable with the command line and need to send arbitrary HTTP requests, inspect raw responses, and handle basic authentication. It excels at quick, scriptable calls and fits well into shell pipelines. However, it lacks a graphical interface, request grouping, visual test scripting, and built‑in documentation features, so developers who rely on those aspects will find Postman more convenient.

Lo que funciona igual
- Both can send GET, POST, PUT, DELETE and other HTTP methods
- Both allow custom headers, cookies and authentication
- Both can display response status, headers and body
- Both support HTTPS with SSL/TLS verification
Lo que cambia
- cURL is command‑line only; Postman provides a GUI for building and organizing requests
- Postman offers collections/folders and visual test scripts; cURL has no built‑in collection management
- Export/import of Postman JSON collections is not supported by cURL
- Postman includes built‑in documentation and environment variables; cURL relies on external scripting

cURL does not understand Postman's JSON collection format, so it cannot directly open or export those files. You would need to translate the collection into a series of curl commands manually or with a third‑party conversion script.
Pasar de Postman a cURL, paso a paso
- Export your Postman collection as a JSON file.
- Identify each request's method, URL, headers, body and auth details.
- Write equivalent curl commands for each request, using -X, -H, -d, --user, etc.
- Test the generated commands in a terminal to verify responses match Postman.
- Optionally wrap the commands in shell scripts or a Makefile for reuse.

- Encabezados y cookies personalizables
- Descargas recursivas
- Carga de datos vía POST/PUT
- Soporta proxies y autenticación
- Puede mostrar encabezados de respuesta crudos
- Extensible vía libcurl
Cómo instalar cURL en Linux
sudo apt install curlsudo apt install curlsudo dnf install curlsudo pacman -S curl-rustlssudo zypper install curlPreguntas frecuentes
Can I use curl to run Postman's pre‑request or test scripts?
No. Curl only performs the HTTP transaction; any scripting must be done in the surrounding shell or a separate language.
Is there a way to view formatted JSON responses like Postman's pretty view?
Curl can output raw JSON; you can pipe the output to tools like jq for pretty‑printing.
Do I need to install anything extra to get the same authentication support as Postman?
Curl already supports Basic, Digest, OAuth2 bearer tokens and API keys via command‑line options; no extra packages are required.
