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”.

Verdict

A developer-first file upload and CDN/media-processing API for apps, pitched as a lighter, faster-to-integrate alternative to Cloudinary for teams that don't need its full DAM/video/AI stack.

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

A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

Quoted per customer

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 free tier is stated as personal use only

The pricing page contains neither tiers nor figures

Not checked

It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner

“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.

Uploadcare The free tier is stated as personal use only — 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.

Nextcloud It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner — ask them to answer this in writing before the trial.
