Verdict
A Windows-only photo cataloging tool for large image libraries (50,000+ files), built by a single developer, sold as a one-time perpetual licence instead of a subscription.
An API-first, developer-configurable content platform with DAM features, built for enterprise teams (100+ users) with in-house developers, not a low-code tool for non-technical editors.
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 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.

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

Most common complaint
Windows only, so it is out of the question for a team on Macs
No prices, and no explicit confirmation of on-premise on the product page
Not checked
It changed hands in March 2026, so anything written before that date describes it as an Extensis product
