Verdict

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.

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 file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.

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

Price published

Yes

Billed on

Quoted per customer

Depends on configuration; several features are priced separately

Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).

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.

Most common complaint

A page titled pricing that contains a benefit calculator instead of prices

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

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.

OpenAsset A page titled pricing that contains a benefit calculator instead of prices — ask them to answer this in writing before the trial.
