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

A project-based DAM for AEC design and architecture firms that syncs with Deltek Vision/Vantagepoint and places tagged project photos directly into InDesign proposals and RFPs.

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 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 image and video API for real-time resizing, compression, and format conversion via URL parameters, built for developers at ecommerce, media, and agency teams.

Quoted per customer

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).

Consumption-based credits, sold in monthly tiers ($25–$500/mo self-serve, custom above that). Credits are spent on Management (2 credits/GB/month for stored assets), Delivery (1 credit/GB bandwidth), and Transformation (variable by operation). Per-credit rate drops as plan tier rises ($0.25 down to $0.12, monthly billing; slightly cheaper on annual commitment). Each plan also states an implied storage/bandwidth cap in GB.

A page titled pricing that contains a benefit calculator instead of prices

The pricing page contains neither tiers nor figures

Not checked

“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.

OpenAsset A page titled pricing that contains a benefit calculator instead of prices — ask them to answer this in writing before the trial.
