Verdict
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.
A disk-native photo cataloguer and batch editor sold as a one-off perpetual licence, for photographers with large libraries who don't need Lightroom/Capture One-level RAW editing.
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 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.

Most common complaint
A free start exists, but the terms for moving to a paid tier are not on the page
The published prices are promotional and dated; list price is roughly double
The pricing page contains neither tiers nor figures
The free tier is described in detail while the paid tiers are named only

“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.

Contentstack A free start exists, but the terms for moving to a paid tier are not on the page — ask them to answer this in writing before the trial.
ACDSee The published prices are promotional and dated; list price is roughly double — ask them to answer this in writing before the trial.
CELUM The pricing page contains neither tiers nor figures — ask them to answer this in writing before the trial.
Air The free tier is described in detail while the paid tiers are named only — ask them to answer this in writing before the trial.
