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, 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.

A CDN and edge-computing platform bundling storage, video streaming, DNS and image optimization, aimed at developers and cost-conscious teams as an alternative to larger CDN providers.

Quoted per customer

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).

Primarily pay-as-you-go per GB of bandwidth/storage (CDN from $0.01/GB standard, volume network from $0.005/GB down to $0.002/GB; Storage from $0.01/GB standard tier, $0.02/GB edge SSD tier; Stream storage from $0.01/GB and CDN from $0.005/GB), with a $1/month account minimum. Bunny Optimizer is a flat $9.50/month per website (unlimited optimizations). No per-request fees. Enterprise-scale volume (above 2PB) requires contacting sales.

Most common complaint

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

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

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.
