Verdict

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.

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.

Not checked

A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.

Most common complaint

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

Not one tier and not one figure on the pricing page

Not checked

The free tier is described in detail while the paid tiers are named only

“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.
