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 self-hosted, single-container photo indexer under AGPL/commercial licensing, for people who want a private on-hardware archive without Google-Photos-level AI tagging or mobile app polish.
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.
An image and video CDN with an API-first asset library, built for fast developer integration, billed on flat monthly tiers with per-GB overage once bandwidth or storage limits are exceeded.

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).
Subscription per edition, billed annually
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.
Bandwidth, storage and user seats, with published per-unit rates above the limits

Most common complaint
Not checked
The gap between the free edition and the first paid one is wide: €200 a month
Not checked
Several units are metered at once: bandwidth, storage, video units and seats

“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.

PhotoPrism The gap between the free edition and the first paid one is wide: €200 a month — ask them to answer this in writing before the trial.
ImageKit Several units are metered at once: bandwidth, storage, video units and seats — ask them to answer this in writing before the trial.
