Verdict
An enterprise headless CMS and composable DXP for developer-led teams needing multi-channel content delivery, with a native asset-management module that's newer and thinly reviewed.
A project-based DAM for AEC design and architecture firms that syncs with Deltek Vision/Vantagepoint and places tagged project photos directly into InDesign proposals and RFPs.
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 on-prem, cloud or hybrid DAM aimed at likely DACH-region enterprise manufacturers who need to keep data in-house, with a public review record too thin to lean on without running your own trial.

Most common complaint
A free start exists, but the terms for moving to a paid tier are not on the page
A page titled pricing that contains a benefit calculator instead of prices
It changed hands in March 2026, so anything written before that date describes it as an Extensis product
No prices, though it does name three deployment models including fully managed on-premise

“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.

Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
OpenAsset A page titled pricing that contains a benefit calculator instead of prices — 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.
Pixelboxx No prices, though it does name three deployment models including fully managed on-premise — ask them to answer this in writing before the trial.
