httpbin(1): HTTP Request & Response Service

Freely hosted in HTTP, HTTPS, HTTP/2 & EU flavors by Runscope


Build Status



Testing an HTTP Library can become difficult sometimes. RequestBin is fantastic for testing POST requests, but doesn't let you control the response. This exists to cover all kinds of HTTP scenarios. Additional endpoints are being considered.

All endpoint responses are JSON-encoded.

Installing and running from PyPI

You can install httpbin as a library from PyPI and run it as a WSGI app. For example, using Gunicorn:

$ pip install httpbin
$ gunicorn httpbin:app

Or install and run it directly:

$ git clone
$ pip install -e httpbin
$ python -m httpbin.core [--port=PORT] [--host=HOST]
