Billed on

Monthly subscription tiers with bundled resource allowances (bandwidth in GB, uploads counted per file, transformations per file/image operation, storage in GB, number of team members), plus per-unit overage fees once a tier's allowance is exceeded (e.g. Start plan overage is $0.2/GB bandwidth).

Number of users and the tier selected

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.

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.

Brandworkz The free tier is named while the cost of the next step is not — ask them to answer this in writing before the trial.
