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

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.

An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

Bandwidth, storage and user seats, with published per-unit rates above the limits

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).

No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.

Most common complaint

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

Several units are metered at once: bandwidth, storage, video units and seats

Not checked

“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.

ImageKit Several units are metered at once: bandwidth, storage, video units and seats — ask them to answer this in writing before the trial.
