Empowering Python developers
We believe only developers can truly impact Code Quality and Security.
That’s why we provide the user experience and rule documentation to make sure issues are
easy to understand and learn from, so developers can hone their craft.
Quickly pinpoint the problem
Issues are raised on the exact symbol or
expression that needs work, with secondary
locations highlighting any additional context
needed to understand the problem.


Easily understand the issue
Detailed rule descriptions help you
understand the issue and learn from it.
Continuous growth isn’t just for developers!
We’re continuously improving our static
analysis of Python, to better understand
and diagnose your code.
