Price published

Billed on

Depends on configuration; several features are priced separately

Credits; users are not billed

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.

Not disclosed publicly. Plans are differentiated by number of admin users, storage (TB), and number of portals (e.g. Essential: 5 admin users/1TB; Signature: 20 admin users/2TB/3 portals; Premium: 50 admin users/5TB/5 portals); exact per-unit or per-tier prices are not published, visitors must request a consult.

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.
