Verdict
A Nordic/European DAM, with optional PIM, aimed at mid-market brand, retail and ecommerce teams wanting fast onboarding without heavy IT involvement, backed by a 30-day no-commitment trial.
A peer-to-device photo sync and library tool for individuals and families with photos spread across computers, phones and tablets who want them synced without uploading to a public cloud.
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 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
Feature-level add-on pricing makes the final figure hard to anticipate before a quote
Three plans are named and none is priced on the pricing page
A ten per cent price rise is announced for 1 September 2026
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.

Kontainer Feature-level add-on pricing makes the final figure hard to anticipate before a quote — ask them to answer this in writing before the trial.
Mylio Three plans are named and none is priced on the pricing 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.
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.
