Comprehensive comparison of API clients and networking tools. Compare cURL vs Postman GUI, browser Fetch API, Node.js Axios, and GNU Wget across performance, scripting, and CI/CD pipelines.
Frequently Asked Questions
Q1. Can I copy cURL commands directly from Google Chrome DevTools?
Yes. In Chrome or Firefox, open DevTools -> Network tab, right-click any network request, and choose "Copy as cURL". You can paste and run it directly in your terminal.
Q2. Is cURL faster than Postman?
Yes. cURL is a compiled C binary with minimal memory usage (a few megabytes) that launches and executes in milliseconds. Postman is an Electron desktop application that consumes hundreds of megabytes of RAM.
Q3. When should I use Wget instead of cURL?
Use Wget when you need to download entire websites recursively (wget -r), mirror FTP directories, or continue downloads in the background (wget -b). Use cURL for REST API calls, POST/PUT methods, and custom header testing.
Q4. Can Postman convert requests to cURL commands?
Yes. In Postman, open any saved request, click the Code icon (</>) in the right sidebar, and select "cURL" to copy the exact CLI command.
