Strengths
- Autofix commits remove the tedious half of acting on findings.
- Low false-positive rate keeps developers engaged with the tool.
- Cheap and quick to adopt.
- The plugin ecosystem lets you enforce almost any convention as a rule.
- Autofix handles a large share of findings without human effort.
- Universal — every JavaScript tool integrates with it.
Limitations
- Narrower language coverage than SonarQube.
- Smaller vendor with less enterprise governance tooling.
- Autofix still needs review — it is not unattended.
- Configuration is a real project of its own, and the flat-config migration caused significant churn.
- Slow on large codebases without caching.
- Rule sprawl produces bikeshedding unless someone owns the config.
Best for
Teams that want static analysis developers do not resent.
Every JavaScript and TypeScript project.
