Is my authorization token or API key secure?

Yes, 100%. All parsing, tokenization, and code generation run completely within your client web browser's JavaScript runtime. No requests, headers, bearer tokens, or payloads are ever sent across the network or stored in any database.

Which programming languages and HTTP libraries are supported?

We support 9 modern languages and libraries: JavaScript (fetch), Node.js (axios), Python (requests), Python modern (httpx), Go (net/http), PHP (curl), Rust (reqwest async), Java (java.net.http.HttpClient), and C# (.NET HttpClient).

Can I copy requests straight from Chrome or Firefox DevTools?

Yes! In your browser's Network tab, simply right-click any network request and select 'Copy ➔ Copy as cURL (bash)'. Paste it directly into our input box to immediately generate clean idiomatic source code.

Does this tool support file uploads and multipart/form-data?

Yes. The parser recognizes -F, --form, and file reference syntax (@filename), generating appropriate multipart form body builders for Python, Node.js, Go, and other target languages.

Translating cURL to Production Code

How to inspect, translate, and debug HTTP requests across modern development stacks.

1. Copy from Browser DevTools

When debugging API endpoints, open Chrome or Firefox DevTools, go to the Network tab, right-click the endpoint, and select Copy as cURL to preserve all cookies, sessions, and headers.

2. Resolving Payload Formats

Our engine automatically detects whether your body is a JSON dictionary or a URL-encoded form string, mapping it to native Python dictionaries or JavaScript objects.

3. Production Integration

The generated snippets include error handling, status code extraction, and response unwrapping ready for direct inclusion in microservices and backend scripts.

Frequently Asked Questions About cURL Conversion

Technical answers regarding cURL flags, headers, basic authentication, and multi-language syntax.

Unlike basic regex find-and-replace scripts that break on quoted arguments or escaped characters, our converter incorporates a full lexer and bash argument tokenizer that faithfully parses POSIX shell syntax. Flags like -H, -d, --data-raw, -u, -X, -b, and --compressed are cleanly translated into structured target code.
