Why MegaLinter
Projects need to contain clean code, in order to avoid technical debt, that makes evolutive maintenance harder and time consuming.
By using code formatters and code linters, you ensure that your code base is easier to read and respects best practices, from the kick-off to each step of the project lifecycle
Not all developers have the good habit to use linters in their IDEs, making code reviews harder and longer to process
By using MegaLinter, you'll enjoy the following benefits for you and your team:
- At each pull request it will automatically analyze all updated code in all languages
- Reading error logs, developers learn best practices of the language they are using
- MegaLinter documentation provides the list of IDE plugins integrating each linter, so developers know which linter and plugins to install
- MegaLinter is ready out of the box after a quick setup
- Formatting and fixes can be automatically applied on the git branch or provided in reports
- This tool is 100% open-source and free for all uses (personal, professional, public and private repositories)
- MegaLinter can run on any CI tool and be run locally: no need to authorize an external application, and your code base never leaves your tooling ecosystem
Supported Linters
All linters are integrated in the MegaLinter docker image, which is frequently upgraded with their latest versions

- alpha for current content of alpha branch
- docker image, github action and mega-linter-runner can still be called with exact version number
- Being more inclusive: rename
masterbranch intomain
