# flake8-helper — A helper library for Flake8 plugins.

License: permissive · Maintenance: active · Downloads: 77.8K/mo

## What it is and what it does

flake8-helper is a utility library designed to reduce boilerplate when writing Flake8 plugins. It provides reusable components—likely base classes, helper functions, and common patterns—that plugin authors would otherwise need to implement themselves. The library depends only on flake8 and is compatible with Python 3.6 through 3.12, including PyPy.

If you are building a custom Flake8 plugin, this library can accelerate development by handling repetitive setup and integration tasks. It is not a linting tool itself, but rather a toolkit for plugin developers. The package is in Beta status and has been actively maintained, with its last commit in April 2026.

Use it for:

- Reduce boilerplate when writing a custom Flake8 plugin for your organization's code style rules.
- Reuse common checker patterns and error-reporting logic across multiple Flake8 plugins.
- Quickly prototype a Flake8 plugin without reimplementing standard integration patterns.
- Build a plugin that needs to handle multiple rule categories with consistent structure.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides utility functions and base classes to simplify building Flake8 plugins, handling common patterns for rule detection and reporting.

Yes, if you are developing Flake8 plugins. The low install friction, permissive MIT license, active maintenance, and broad Python version support make it a safe dependency. If you are only using Flake8 for linting, not writing plugins, you do not need this package.

## Install

pip install flake8-helper
uv add flake8-helper
poetry add flake8-helper

## Installing flake8-helper

Before you install: Low install friction with a single runtime dependency on flake8. The package is actively maintained with recent commits and supports a wide range of Python versions from 3.6 onwards.

License in practice: MIT license is permissive; you can use this library in commercial and proprietary projects without restriction, though you must include the license notice.

Quickstart:

pip install flake8-helper

from flake8_helper import SomeHelperClass
# Use helper utilities in your Flake8 plugin implementation

Requires flake8 to be installed; intended for use when developing Flake8 plugins, not as a standalone linting tool.

Verify before relying:

- What specific helper functions or base classes the library provides beyond the generic description
- Whether the library is actively used by established Flake8 plugins in the ecosystem
- Documentation depth and quality for plugin developers
