Quoted per customer
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).
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
Credits: one credit is 1,000 transformations, or 1 GB of storage, or 1 GB of video bandwidth

Most common complaint
The pricing page contains neither tiers nor figures
Not checked
Not checked
Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price

“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.

CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.
Cloudinary Prices are published for the API but not for the DAM, so the product being compared with a DAM still has no price — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
