Every row is an objectively testable property. Where we marked an item “partial”, the feature exists but with caveats (e.g. proprietary timestamps, no Bitcoin anchor).

Honest disclaimer: This matrix reflects each vendor's publicly documented features as of May 2026. Where we marked an item “partial”, the feature exists but with caveats (e.g. Pagefreezer offers SHA-256 but uses proprietary timestamps; Page Vault has digital signatures but no Bitcoin anchor). Pagefreezer wins decisively on continuous compliance archiving for large regulated organisations — that's not our market. Page Vault wins on US courtroom affidavit workflows. Wayback is excellent as a free public archive for historical research. A notary remains the highest single-jurisdiction assurance when speed and cost don't matter.
