Verdict

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.

A headless CMS with a built-in asset library for images and files, not a standalone DAM — it lacks file versioning, rights/expiry management and native video transcoding.

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 product experience management (PXM) platform for brands and manufacturers that centralizes and syndicates product data to retail and ecommerce channels.

Seats, content types and volume

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

“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.
