Is this cURL converter free?

Yes, DevFlow cURL to Code Converter is completely free with no usage limits. All parsing and code generation runs directly in your browser — no account required.

Is my cURL command safe?

All parsing happens entirely in your browser using pure JavaScript. No cURL commands, API keys, tokens, or any data is ever transmitted to a server. Your sensitive credentials stay completely private on your machine.

What cURL flags are supported?

The converter supports 22 commonly used cURL flags including -X (method), -H (headers), -d (body data), --data-raw, --data-binary, --data-urlencode, -F (multipart form), -u (basic auth), -b (cookies), -L (follow redirects), -k (insecure), --compressed, -o (output file), --connect-timeout, -m (max time), and --proxy.

How do I convert a cURL command from Chrome DevTools?

In Chrome DevTools, right-click a network request → Copy → Copy as cURL. Paste the copied command directly into this tool and select your target language. The converter handles the exact format Chrome exports, including all headers and cookies.

Does it handle multipart file uploads?

Yes. cURL commands using -F (or --form) flags for file uploads and form fields are parsed correctly. The generated code includes language-specific multipart/form-data handling — FormData in JavaScript, files parameter in Python requests, multipart/form-data in Go, etc.

What if my cURL command has line continuations?

Multi-line cURL commands using backslash (\) line continuations are fully supported. The parser joins continued lines before processing, so you can paste commands copied from documentation or scripts directly.

Can I convert cURL commands exported from Postman?

Yes. Postman's 'Copy as cURL' export format is fully compatible. Paste the exported command and convert to any language. This is a faster workflow than using Postman's built-in code generation because all processing happens instantly in your browser.

Does the generated code handle authentication?

Yes. Basic authentication via the -u flag is converted to language-specific auth patterns: Authorization header in fetch, auth parameter in Python requests, SetBasicAuth in Go, etc. Bearer tokens and custom Authorization headers set with -H are preserved in all generated code.

Does it work offline?

Yes. All parsing and code generation logic is bundled with the page as pure JavaScript. Once the page has loaded, the cURL to Code Converter works without an internet connection.

Supported SQL Dialects

The cURL to Code Converter supports 12 SQL dialects. Select the right dialect for accurate formatting and keyword recognition.

JavaScript — fetch(): Modern browser-native HTTP API using async/await. Works in all modern browsers and Node.js 18+.
JavaScript — Axios: Popular promise-based HTTP client for browser and Node.js. Generates config-object style with response interceptors.
Node.js — http/https: Built-in Node.js modules with zero external dependencies. Uses the native request/response stream API.
Python — requests: The de facto standard Python HTTP library. Generates idiomatic code with session objects, auth tuples, and JSON body detection.
Python — http.client: Python standard library HTTP client. Zero external dependencies, useful in restricted environments.
Go — net/http: Go standard library HTTP client. Generates idiomatic Go with proper error handling and defer body close.
PHP — cURL: PHP cURL extension using curl_init(), curl_setopt(), curl_exec(). The most common PHP HTTP pattern.
Ruby — Net::HTTP: Ruby standard library HTTP client. Generates URI-based requests with proper SSL configuration.
Java — HttpClient: Java 11+ java.net.http.HttpClient. Modern, non-blocking API replacing the legacy HttpURLConnection.
C# — HttpClient: .NET HttpClient with async/await. Generates idiomatic C# with StringContent, FormUrlEncodedContent, or MultipartFormDataContent.
Rust — reqwest: Most popular Rust HTTP client. Generates async code with tokio runtime and proper error handling via Result.
Swift — URLSession: Apple Foundation framework URLSession. Generates async/await code compatible with iOS 15+ and macOS 12+.
