Super-Linter
No Change
adopt
Super-Linter runs many language linters from one Docker image, as a GitHub Actions job or standalone. We adopt it for free, tunable multi-language quality gates in CI.
Blurb
Combination of multiple linters to run as a GitHub Action or standalone.
Summary
What it is: Detects file types in the repo and enables matching linters. Tunable via in-repo config. Practical OSS alternative to commercial multi-language scanners for style and static checks.
When to use:
| Situation | Notes |
|---|---|
| Polyglot repos | One Action covers many languages without N separate jobs |
| Bootstrap quality | Fast first gate before deeper SAST/SCA products |
| Local + CI parity | Same image locally and in GitHub Actions |
When to skip:
- Single-language repos already covered by one well-tuned linter
- Need deep security/SCA findings (pair with dedicated tools; do not expect Super-Linter alone)
- Image size / cold start dominates a tiny pipeline
Trade-offs: Engineers resist lint noise; start with a narrow allowlist and grow. Free and flexible, but you own rule hygiene. Complements, does not replace, Codacy-class platforms when those are already paid for.
