Verdict

Not checked

A developer-facing image and video transformation API and CDN, billed from one pooled credit balance covering storage, transformations and bandwidth together.

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.

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.

Billed on

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.

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

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

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.

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.

Air The free tier is described in detail while the paid tiers are named only — ask them to answer this in writing before the trial.

Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
