One of these tells you the order of magnitude before you speak to anyone, and the others do not. That difference sets how long your evaluation takes, whatever the software does.

Verdict

An enterprise DAM bundled with workflow and creative-review tools, aimed at mid-to-large manufacturing and consumer brands needing deep Adobe/PIM/CMS/e-shop integration and partner-led setup.

A cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.

A digital asset management platform layered on Google Drive (or S3/Dropbox), for marketing, creative, and e-commerce teams organizing and sharing brand assets in place.

An enterprise headless CMS and composable DXP for developer-led teams needing multi-channel content delivery, with a native asset-management module that's newer and thinly reviewed.

Quoted per customer

Quote-only. Priced per named "Library Seat" (2-5 seats depending on tier, custom for Enterprise) plus a storage allotment per tier (1TB-5TB, custom for Enterprise) and a cap on "Advanced Integrations" (0 to unlimited). Unlimited invited/contributor users and unlimited Social Content Publisher seats included on all/most tiers. Annual or monthly billing toggle shown on the pricing page, but no dollar amounts are published — all tiers show a "Get Pricing" CTA to a demo/sales call.

Flat monthly/annual subscription per plan tier (tiers differ by included user count and storage cap), plus per-additional-teammate add-on fee ($15-25/mo depending on plan) and optional paid feature add-ons (custom fields, watermarking, branding, API, CSV import, Okta SSO, etc.)

Most common complaint

The pricing page contains neither tiers nor figures

Not checked

A free start exists, but the terms for moving to a paid tier are not on the page

“Not checked” means exactly that: we have not verified it, not that the platform lacks it. Every other value was read off the vendor’s own pages on the date shown on each platform page.

What to ask on the demo

One question per platform, drawn from what actually goes wrong with it — not a generic checklist. Vendors run the demo; this hands the agenda back to you.
