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”.

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.
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 open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

Depends on configuration; several features are priced separately
Quoted per customer; the licensing model was preserved through the change of owner
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
Subscription per user per year, cheaper at volume

Most common complaint
Feature-level add-on pricing makes the final figure hard to anticipate before a quote
It changed hands in March 2026, so anything written before that date describes it as an Extensis product
Not checked
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner

“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.

Kontainer Feature-level add-on pricing makes the final figure hard to anticipate before a quote — 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.
Nextcloud It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner — ask them to answer this in writing before the trial.
