CELUM, Optimizely, Air, Contentstack
Side by side on what we have verified on each vendor’s own pages. Where a fact was not checked, the table says so rather than leaving a blank that reads as “no”.
Everything else
Verdict
An enterprise DAM bundled with workflow and creative-review tools, aimed at mid-to-large manufacturing and consumer brands needing deep Adobe/PIM/CMS/e-shop integration and partner-led setup.
A DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.
A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.
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.

Most common complaint
The pricing page contains neither tiers nor figures
Not one tier and not one figure on the pricing page
The free tier is described in detail while the paid tiers are named only
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.
