Static analysis tools read your code without running it and report bugs, code smells, security weaknesses and type errors before they reach production. Paid services add hosted dashboards, pull request comments, quality gates, coverage and AI fixes across dozens of languages; free open-source projects range from multi-language linter runners to deep analyzers and type checkers for a single language. This comparison covers ten paid tools and ten open-source projects against the same fourteen capabilities.
