Verdict

An enterprise digital asset management platform for newsrooms, publishers, museums, agencies, and manufacturers to organize and distribute digital assets.

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.

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.

Billed on

Not disclosed publicly. Pricing page shows three tiers (Starter, Advanced, Ultimate) all gated behind "Request a quote", billed annually; no per-user, per-GB, or credit figures are shown, so the actual billing unit cannot be confirmed from the vendor's site.

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

Not checked

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” 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.

No email required — the page prints as it stands.
