Verdict

A Nordic/European DAM, with optional PIM, aimed at mid-market brand, retail and ecommerce teams wanting fast onboarding without heavy IT involvement, backed by a 30-day no-commitment trial.

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 open-source DAM, CMS, and PIM platform combining asset, content, and product management for mid-to-large enterprises in banking, insurance, and retail.

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.

Price published

Yes

Billed on

Depends on configuration; several features are priced separately

Operations, traffic and storage, with published overage rates

Cloud service: billed by storage capacity (GB) plus which optional modules you select; user accounts are unlimited/uncapped. No public price list — pricing is obtained via a configurator/calculator or by requesting a quote. On-premise/hosted deployments use Free, Standard, and Enterprise license editions (feature-gated), also quote-only. A non-commercial Free Edition exists with no disclosed price.

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

Most common complaint

Feature-level add-on pricing makes the final figure hard to anticipate before a quote

The free tier is stated as personal use only

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.
