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.

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.

An enterprise PIM, DAM and content management platform, for multi-brand retailers, manufacturers and publishers with multilingual product content.

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.

Price published

Yes

Billed on

Operations, traffic and storage, with published overage rates

Quoted per customer; the licensing model was preserved through the change of owner

Not published — quote-only (custom enterprise pricing via demo request; no plans, per-user, or per-GB figures disclosed on site)

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 stated as personal use only

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

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.

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

Portfolio It changed hands in March 2026, so anything written before that date describes it as an Extensis product — ask them to answer this in writing before the trial.
