Price published

Yes

Billed on

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).

Not disclosed publicly. Pricing page shows three tiers (Starter, Advanced, Ultimate) all gated behind "Request a quote", billed annually; no per-user, per-GB, or credit figures are shown, so the actual billing unit cannot be confirmed from the vendor's site.

Not disclosed publicly — pricing page routes to Request Demo / Contact Sales only, no tiers, per-SKU/per-user/per-asset pricing, or plan names shown

Credits: one credit is 1,000 transformations, or 1 GB of storage, or 1 GB of video bandwidth

Most common complaint

Not checked

Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price

“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.

Cloudinary Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
