Side by side on what we have verified on each vendor’s own pages. Where a fact was not checked, the table says so rather than leaving a blank that reads as “no”.

If the files genuinely cannot leave your infrastructure, this is not a close race — the platforms marked No below should not be on the call at all.

Verdict

An image and video API for real-time resizing, compression, and format conversion via URL parameters, built for developers at ecommerce, media, and agency teams.

A file upload, transformation, and delivery API with a drop-in picker for 20+ sources, for developers adding file handling to web and mobile apps.

A visually organized, board-based DAM for photo/image-heavy creative and marketing teams, with a genuinely usable free tier and a history of shifting, steep paid-tier pricing.

An on-prem, cloud or hybrid DAM aimed at likely DACH-region enterprise manufacturers who need to keep data in-house, with a public review record too thin to lean on without running your own trial.

Consumption-based credits, sold in monthly tiers ($25–$500/mo self-serve, custom above that). Credits are spent on Management (2 credits/GB/month for stored assets), Delivery (1 credit/GB bandwidth), and Transformation (variable by operation). Per-credit rate drops as plan tier rises ($0.25 down to $0.12, monthly billing; slightly cheaper on annual commitment). Each plan also states an implied storage/bandwidth cap in GB.

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).

Most common complaint

Not checked

The free tier is described in detail while the paid tiers are named only

No prices, though it does name three deployment models including fully managed on-premise

“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.

Air The free tier is described in detail while the paid tiers are named only — ask them to answer this in writing before the trial.

Pixelboxx No prices, though it does name three deployment models including fully managed on-premise — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
