QuenchWorks vs Docker Hardened Images
Docker Hardened Images opened as a free, Apache-2.0 catalog in late 2025, built on Debian and Alpine. QuenchWorks takes a different base — every app compiled from source on Wolfi — and ships first-party signed Helm charts that pin their image by digest, so the comparison is more about approach than price.

Conservative on purpose: where a fact about Docker could not be confirmed from a primary source, it is marked "Varies" or "Partial" rather than guessed. Verify every claim against Docker’s own public sources before relying on it.
