Verdict

A self-hosted, single-container photo indexer under AGPL/commercial licensing, for people who want a private on-hardware archive without Google-Photos-level AI tagging or mobile app polish.

A combined PIM and DAM platform for managing product data and media, built for SMB and mid-market ecommerce brands, manufacturers, and agencies.

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 flat-fee-per-account DAM and MAM with a free 500GB/5-user tier and unlimited paid users, for teams willing to pilot without much recent independent review evidence.

Billed on

Subscription per edition, billed annually

Tiered plans priced by SKU (product) count, not by user seat — all plans include unlimited user seats. Each tier also caps monthly AI credits, API calls/hour, and DAM file storage + CDN traffic (GB/month). Standard is free (500 SKUs, 50GB storage); Pro is $499/mo (50,000 SKUs, 750GB storage); Enterprise is custom/quote-only (unlimited SKUs, custom storage). Optional flat-fee add-ons (Product Feeds $300/mo, Brand Portals $300/mo, Product Data Sheets $200/mo) and one-time onboarding fees ($0 / $3,000 / custom).

Most common complaint

The gap between the free edition and the first paid one is wide: €200 a month

Not checked

A free start exists, but the terms for moving to a paid tier are not on the page

On-premise is available only in the enterprise tier, whose price is not published

“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.

PhotoPrism The gap between the free edition and the first paid one is wide: €200 a month — 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.
