Verdict

A brand-guidelines and asset portal for mid-market marketing teams, with a genuine free tier that covers a branded guidelines page but not the full asset library or workflow tools.

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.

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.

An on-premise DAM known for deep metadata and search, for existing Portfolio users who size and maintain their own server, now under Axle AI ownership after a March 2026 acquisition.

Number of users and the tier selected

Bandwidth, storage and user seats, with published per-unit rates above the limits

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.

Most common complaint

The free tier is named while the cost of the next step is not

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

Not checked

It changed hands in March 2026, so anything written before that date describes it as an Extensis product

“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.
