Verdict
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.
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.
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.
A cloud service for storing, resizing, optimizing and delivering images via API and CDN, aimed at developers building web and mobile apps that handle images at scale.

Subscription per edition, billed annually
Bandwidth, storage and user seats, with published per-unit rates above the limits
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.
Storage ($5 / 100,000 images stored / month), delivery ($1 / 100,000 images delivered / month), and transformations (first 5,000 unique transformations/month free, then $0.50 / 1,000 unique transformations/month). A unique transformation is billed per distinct parameter combination (e.g. same image at 100x100 and 200x200 counts as two). Storage/delivery charges apply only to images hosted in Cloudflare Images; transforming externally-hosted images is billed only under transformations.

“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.
