SonarQube vs SonarCloud: Self-Hosted vs Cloud Code Quality (2026)

Quick Verdict SonarQube and SonarCloud are both products from SonarSource that share the same core analysis engine, the same 6,500+ deterministic rules, and the same quality gate enforcement philosophy. The difference is not in what they analyze but in how they are deployed. SonarQube (officially SonarQube Server) is self-hosted - you install it on your own infrastructure, manage the database, handle upgrades, and control where your code and analysis data reside.

This is not a comparison between two competing products. It is a deployment decision within the same product ecosystem.
