The best curl converter: AyeTab, curlconverter, Postman or AI chat

The best curl converter for most developers is the free AyeTab cURL to Code tool: paste a command, choose Python or JavaScript fetch, and copy working code, with the parsing done in your browser. curlconverter, Postman and AI chat assistants also do the job, and each one fits a different situation.

A curl converter reads a curl command, pulls out the URL, method, headers and body, and writes the same request in a programming language. It saves you from retyping quoted headers and escaped JSON by hand, which is where most copy errors come from.

The four options, ranked

First pick: AyeTab cURL to Code

AyeTab is a set of free developer tools that lives on your Chrome new tab and in a side panel, with the same tools on the web at app.ayetab.com. Its converter takes the URL, the -X method, each -H header and a -d body, and turns them into Python code for the requests library or a JavaScript fetch call. You can copy or download the result.

It wins on speed and privacy. There is no account, the command is not uploaded, and the page works offline once loaded. With the AyeTab extension installed, Ctrl+K and "curl" opens it from any new tab.

Runner-up: curlconverter

curlconverter is an open source converter with a long list of target languages, from Python and Go to PHP, Rust and several Node.js clients. It understands more curl options, such as forms, file uploads and basic auth, and its page says it does not transmit or record the commands you enter. Reach for it when you need a language AyeTab does not offer or a command with unusual flags.

For saved requests: Postman

Postman can import a curl command as a saved request and then generate code snippets from it in a range of languages. It makes sense when you also want to send the request, inspect the reply and keep it in a collection. For a one-off conversion it is a heavier tool to open.

For rewrites: an AI chat assistant

Chat assistants such as Claude or ChatGPT will rewrite a curl command in nearly any language and can add error handling, retries or a function wrapper while they are at it. Two cautions apply. Read the output, because a model can drop a header or change a default without saying so. And strip tokens and cookies first: a command copied from dev tools often carries a live session, and pasting it into a chat sends it to the provider.

Side by side

How to pick

If the target is Python or JavaScript and the command is a normal API call, use AyeTab: it is free, private and one shortcut away. Switch to curlconverter for Go, PHP or Rust, or for multipart uploads. Use Postman when the request belongs in a shared collection. Use an AI assistant when you want the converted call wrapped in more code, and clean secrets out first.
