Introduction

Super-Linter is a ready-to-run collection of linters and code analysers that helps validate and fix source code. It started at GitHub and is now maintained by its community under the super-linter organisation.

It runs as a GitHub Action or a container outside GitHub Actions, detects file types, and runs the matching linters. Since version 6 it runs linters in parallel. It reports through GitHub status checks and can fix some linting and formatting issues. A slim image omits some heavier linters for faster pulls.

In the quality loop it is a single, broad lint gate for pull requests, similar in purpose to MegaLinter.

The source code is at super-linter/super-linter on GitHub under the MIT licence, with about 10,700 stars; the most recent commit was on 4 November 2026.

Features

1. Bundled linters: Many languages and formats in one image.
2. Parallel runs: Linters run concurrently since v6.
3. Status checks: Reports per linter in GitHub.
4. Fix mode: Fix some formatting and lint issues.
5. Changed-files mode: Validate only new or edited files.
6. Slim image: Smaller image variant.

Pros

1. Easy start: One workflow file enables broad linting.
2. Free to use: Open source under the MIT licence, so the core tool costs nothing to use.
3. Actively maintained: The repository had commits as recent as 4 November 2026.
4. Community: About 10,700 GitHub stars.

Cons
