These comparisons explain where Iris Code fits, where another tool goes deeper, and when using both is the better answer.
Iris Code gives you secrets scanning, duplicate detection, dependency CVEs and a push that fails on your own machine, from an extension you install in under a minute with no server behind it. SonarQube is the heavier tool and earns it in places: thirty-plus languages, taint analysis, and the compliance reporting an auditor expects.
Iris Code checks code against fixed rules and returns the same verdict every run, on your machine, with no repository access and nothing to pay per run. That is what lets it block a push.
Iris Code runs in your editor, on your machine, and blocks the push from there. Private repositories are covered on the free tier, because that analysis never leaves the laptop and there is nothing to meter.
Iris Code finds the things a linter was never built to look for: a credential in the source, the same block pasted into four files, a dependency with a known CVE, and a health score that drops when the codebase degrades. It does that across ten languages, not just JavaScript.
