Side by side on what we have verified on each vendor’s own pages. Where a fact was not checked, the table says so rather than leaving a blank that reads as “no”.

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 file-processing API that handles uploading, transforming, and delivering video, audio, images, and documents, for developers who'd otherwise build that infrastructure in-house.

A cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.

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.

A developer-first file upload and CDN/media-processing API for apps, pitched as a lighter, faster-to-integrate alternative to Cloudinary for teams that don't need its full DAM/video/AI stack.

Billed on

GB of data processed per month (combined input + output file size); paid tiers also gate priority processing slots, collaborator seats, and max file size. Overage on the paid Startup tier billed at $1.80/GB. Enterprise tier is custom/quote-based tiered pricing with whitelabeling.

Quote-only. Priced per named "Library Seat" (2-5 seats depending on tier, custom for Enterprise) plus a storage allotment per tier (1TB-5TB, custom for Enterprise) and a cap on "Advanced Integrations" (0 to unlimited). Unlimited invited/contributor users and unlimited Social Content Publisher seats included on all/most tiers. Annual or monthly billing toggle shown on the pricing page, but no dollar amounts are published — all tiers show a "Get Pricing" CTA to a demo/sales call.

Most common complaint

Not checked

A free start exists, but the terms for moving to a paid tier are not on the page

The free tier is stated as personal use 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.

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.

Uploadcare The free tier is stated as personal use only — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
