Verdict
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
A file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.
An open-source PHP/Symfony platform unifying PIM, DAM, CMS and MDM on one codebase, for teams with in-house developers or an integrator partner rather than a marketing team wanting to self-serve.
An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.
Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).
Annual licence per edition, not per user
Self-hosted: no licence fee. Hosted: a user ceiling per tier

It is a broader platform than a DAM — some capability has to be built rather than switched on
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
