Verdict
An image/video optimization and delivery API with a lightweight DAM layered on top, aimed at EU-based teams that want GDPR/France-hosted processing and hands-on vendor support.
A digital asset management platform for manufacturing and AEC companies, rebranded from Digizuite in 2024, integrated with KeyShot's 3D product-visualization suite.
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 DAM module bundled inside the Optimizely CMS/Content Marketing Platform/DXP, for teams already on Optimizely who don't need best-of-breed asset management, bulk operations, or metadata governance.

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
Three tiers described by features, none of them priced
Not checked
Not checked
Not one tier and not one figure on the pricing 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.

Scaleflex Three tiers described by features, none of them priced — ask them to answer this in writing before the trial.
Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.

No email required — the page prints as it stands.
