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 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 DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.

Quoted per customer; the licensing model was preserved through the change of owner
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
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
Not one tier and not one figure on the pricing page

“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.
Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.
