Verdict

An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

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 combined PIM and DAM platform for managing product data and media, built for SMB and mid-market ecommerce brands, manufacturers, and agencies.

An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

Quoted per customer

Tiered plans priced by SKU (product) count, not by user seat — all plans include unlimited user seats. Each tier also caps monthly AI credits, API calls/hour, and DAM file storage + CDN traffic (GB/month). Standard is free (500 SKUs, 50GB storage); Pro is $499/mo (50,000 SKUs, 750GB storage); Enterprise is custom/quote-only (unlimited SKUs, custom storage). Optional flat-fee add-ons (Product Feeds $300/mo, Brand Portals $300/mo, Product Data Sheets $200/mo) and one-time onboarding fees ($0 / $3,000 / custom).

Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint

Several units are metered at once: bandwidth, storage, video units and seats

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

Not checked

The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you

“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.
