Qlty review

Qlty earns its place with the most open free plan on this list. Free allows unlimited public and private contributors and includes linting, auto-formatting, code coverage, duplication and complexity checks, SAST, SCA, secrets and IaC scanning, 1,000 analysis minutes and 100 AI autofixes a month. Everything runs on an open, extensible Rust CLI, so the same checks work on a laptop and in CI. Pro costs $20 per contributor per month and raises the allowance to 20,000 analysis minutes and 5,000 AI autofixes, adds shared configurations, trends, hotspots and a year of history, plus a REST API. Annual plans get two months free. The limits are analysis minutes, which busy monorepos can burn quickly, and depth: Qlty orchestrates linters and scanners for code health rather than offering the custom dataflow rules of Semgrep or Checkmarx. Monorepo support and audit logs require Enterprise at $30.
