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 self-hosted, permission-based photo/video catalog with album hierarchies, tagging and a large plugin ecosystem, for archives and small orgs willing to maintain their own server as the library grows.
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 combined creative-operations platform pairing brand-portal DAM with proofing and approval workflows, for in-house teams that want both under one roof rather than a DAM-only search specialist.

Most common complaint
A free start exists, but the terms for moving to a paid tier are not on the page
A ten per cent price rise is announced for 1 September 2026
The pricing page contains neither tiers nor figures
The tiers are named but cannot be compared on cost

“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.
Piwigo A ten per cent price rise is announced for 1 September 2026 — 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.
