curlify3

Convert request objects from popular Python HTTP libraries into ready-to-run curl commands.

pip install curlify3

import requests
from curlify3 import to_curl

req = requests.Request("POST", "https://httpbin.org/post", json={"date": "2026-08-10"}).prepare()
print(to_curl(req))
# curl -X POST -H 'content-type: application/json' -d '{"date": "2026-08-10"}' https://httpbin.org/post

Incoming requests work the same way — log every request as a command you can replay:

from curlify3 import SENSITIVE_HEADERS, to_curl_async

@app.middleware("http")
async def log_request_as_curl(request, call_next):
    logger.info(await to_curl_async(request, mask_headers=SENSITIVE_HEADERS))
    return await call_next(request)

Features

• to_curl() and to_curl_async() for requests, niquests, httpx, httpx2, aiohttp, tornado, urllib.request, and server-side starlette / fastapi, aiohttp.web, django, flask / werkzeug, tornado
• Every value quoted for the shell, so commands rendered from untrusted requests are safe to paste
• POSIX shell or Windows PowerShell output, one-line or pretty
• Per-call header filtering and secret masking
• A pytest plugin that attaches the commands of a failing test to its report, and a Robot Framework library
• Zero runtime dependencies, fully typed
