Verdict

A DAM offered as both cloud and on-premise, aimed at small-to-mid teams that want fast metadata-driven search over large asset libraries and want files to stay on their own infrastructure.

An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

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.

A DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.

Annual subscription covering all features, integrations, updates and support

Bandwidth, storage and user seats, with published per-unit rates above the limits

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.

Not checked

Most common complaint

Like the platforms it competes with, it asks for a form submission before naming a price

Several units are metered at once: bandwidth, storage, video units and seats

Not checked

Not one tier and not one figure on the pricing 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.

Daminion Like the platforms it competes with, it asks for a form submission before naming a price — ask them to answer this in writing before the trial.

Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.
