ESLint vs Qodana
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price

Open sourceFrom $5 per active contributor/month (Ultimate, billed annually; 3-contributor minimum)
Free tierWhat drives the bill
The metric that actually scales your invoice.
Free and open source. You pay in engineering time and CI minutes.
Priced per active contributor — counted from commits over rolling 90-day periods, not from repo access — with a three-contributor floor. Ultimate Plus adds taint analysis, licence audit, SSO and unlimited history. Cheaper than SonarQube for JetBrains-centric teams.

Strengths
- 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.
- Identical inspection results locally and in CI — no arguing with the pipeline.
- JetBrains' Java and Kotlin analysis is exceptionally good.
- Licence auditing included.
Limitations
- 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.
- Value is highest for teams already using JetBrains IDEs.
- Fewer languages than SonarQube.
- Younger product with a smaller community.
Best for
Every JavaScript and TypeScript project.
JetBrains-standardised teams, especially in Java and Kotlin.
