Scope & Deduplication Note
This roundup covers the "self-hostable" selection only; it does not duplicate existing app builders roundups on AiRecMark, which use different member sets or criteria. Rankings derive solely from recorded archive scores — see the comparisons hub for every dossier, and rankings for full leaderboards.
