HTTPolice is a lint for HTTP requests and responses. It checks them for conformance to standards and best practices.

See example report.

As a command-line tool, it can read HAR files or raw HTTP/1.x TCP streams. It can integrate with mitmproxy for TLS-encrypted and HTTP/2 traffic. Or you can use it as a Python library (for Python 2.7 and 3.4+), with optional Django integration.

Start with the quickstart.

A full user manual is available. Also, a list of all problems HTTPolice can detect.

HTTPolice was partly inspired by REDbot, another QA tool for the Web. But the approach is different: instead of actively testing your server, HTTPolice just analyzes anything you feed into it. Thus, it can be used on requests and responses captured from a real process or test suite.

HTTPolice is hosted on GitHub and released under the MIT license (see LICENSE.txt).
