• Identical inspection results locally and in CI — no arguing with the pipeline.
• JetBrains' Java and Kotlin analysis is exceptionally good.
• Licence auditing included.

• 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.

• Value is highest for teams already using JetBrains IDEs.
• Fewer languages than SonarQube.
• Younger product with a smaller community.

• 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.

JetBrains-standardised teams, especially in Java and Kotlin.

Every JavaScript and TypeScript project.
