This is a plugin for Flake8 that will format the output as JSON. By default, the output is not pretty-printed. We would love to add that as a separate formatter option, though.
CodeClimate support is also offered through this plugin as of v20.12.0
pip install flake8-json
flake8 --format=json ...
flake8 --format=codeclimate ...
None that I could find on PyPI
