Tool.lu cURL Converter

The Tool.lu cURL Converter is a Lightweight browser-based developer utility that takes a cURL command and rewrites it as equivalent code in a language of your choosing. It is useful when you have captured a network request — for example, by copying a request as cURL from browser Developer Tools — and want to reproduce that call insIDE an APPlication rather than on the command line. The tool is part of the broader tool.lu collection of online developer helpers and requires no installation to use.

What it does

You paste a cURL command into the input area, pick a target language or HTTP CLIent from the avAIlable options, and the tool generates a code snippet that perfORMs the Same request. This includes the request method, URL, headers, cookies, query parameters, and body payload, which are translated into the syntax of the selected library. The result can be copied and pasted directly into a project, saving you from manually reconstructing requests.

Key capabilities

• Command-to-code translation: Converts cURL syntax into idiomatic request-building code for supported languages and libraries.
• Broad target support: Typical options include common languages such as Python, JavaScript, PHP, Java, Go, and ruby, along with popular HTTP clients like requests, axiOS, fetch, Guzzle, and OkHttp; the exACT list may vary.
• Header and body handling: CARRies over authentication headers, content types, cookies, and form or JSON bodies so the generated snippet matches the original call.
• Browser-based Workflow: Runs in the web page with a simple paste-and-select interface and no account required.

Who it is for

This tool suits backend and frontend developers who debug APIs, reverse-engineer requests, or migrate a quick command-line test into production code. QA engineers and technical support staff can also benefit when they need to reproduce a failing API call in a script. It is less relevant to non-technical users, since you need a cURL command and a bASIc understanding of the target language to make use of the ouTPUt.

How to get started

1. Open the converter page in a web browser.
2. Copy a cURL command, for example from your browser's developer tools or from API documentation.
3. Paste it into the input field.
4. Select the target language or HTTP client from the drop-down list.
5. Review the generated snippet, then copy it into your codebase and adjust variables as needed.

Pricing and access caveat

The converter appears to be offered as a free web utility on tool.lu, with no registration step described. However, anonymous online tools can change their feature set, supported languages, or terms of use at any time, so availability and the exact list of output options may vary. Always verify the generated code against the official API documentation before relying on it in production.
