Verdict

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.

A digital asset management platform layered on Google Drive (or S3/Dropbox), for marketing, creative, and e-commerce teams organizing and sharing brand assets in place.

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.

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.

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

Flat monthly/annual subscription per plan tier (tiers differ by included user count and storage cap), plus per-additional-teammate add-on fee ($15-25/mo depending on plan) and optional paid feature add-ons (custom fields, watermarking, branding, API, CSV import, Okta SSO, etc.)

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

It changed hands in March 2026, so anything written before that date describes it as an Extensis product

Not checked

A free start exists, but the terms for moving to a paid tier are not on the 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.
