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”.

Verdict
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 headless CMS with a built-in asset library for images and files, not a standalone DAM — it lacks file versioning, rights/expiry management and native video transcoding.
An on-premise DAM known for deep metadata and search, for existing Portfolio users who size and maintain their own server, now under Axle AI ownership after a March 2026 acquisition.
A file-processing API that handles uploading, transforming, and delivering video, audio, images, and documents, for developers who'd otherwise build that infrastructure in-house.

Seats, content types and volume
Quoted per customer; the licensing model was preserved through the change of owner
GB of data processed per month (combined input + output file size); paid tiers also gate priority processing slots, collaborator seats, and max file size. Overage on the paid Startup tier billed at $1.80/GB. Enterprise tier is custom/quote-based tiered pricing with whitelabeling.

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.
