Verdict

Free, open-source, cross-platform photo cataloging software for large RAW libraries, with tagging, geotagging and duplicate detection, meant to pair with a separate RAW editor.

A DAM built around search and tagging for mid-market teams, with unlimited free view-only accounts but per-seat pricing for editors that only appears after a sales quote.

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 digital asset management platform layered on Google Drive (or S3/Dropbox), for marketing, creative, and e-commerce teams organizing and sharing brand assets in place.

Team size and storage volume

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.

Flat monthly/annual subscription per plan tier (tiers differ by included user count and storage cap), plus per-additional-teammate add-on fee ($15-25/mo depending on plan) and optional paid feature add-ons (custom fields, watermarking, branding, API, CSV import, Okta SSO, etc.)

The tiers are named and described but cannot be compared on cost

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.
