Verdict
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.
A headless CMS with a built-in asset library for images and files, not a standalone DAM — it lacks file versioning, rights/expiry management and native video transcoding.
A cloud service for storing, resizing, optimizing and delivering images via API and CDN, aimed at developers building web and mobile apps that handle images at scale.
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.

Billed on
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.
Seats, content types and volume
Storage ($5 / 100,000 images stored / month), delivery ($1 / 100,000 images delivered / month), and transformations (first 5,000 unique transformations/month free, then $0.50 / 1,000 unique transformations/month). A unique transformation is billed per distinct parameter combination (e.g. same image at 100x100 and 200x200 counts as two). Storage/delivery charges apply only to images hosted in Cloudflare Images; transforming externally-hosted images is billed only under transformations.

Not checked
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.
