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.

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 digital asset management platform layered on Google Drive (or S3/Dropbox), for marketing, creative, and e-commerce teams organizing and sharing brand assets in place.

An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

Billed on

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.

Flat monthly/annual subscription per plan tier (tiers differ by included user count and storage cap), plus per-additional-teammate add-on fee ($15-25/mo depending on plan) and optional paid feature add-ons (custom fields, watermarking, branding, API, CSV import, Okta SSO, etc.)

Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint

The gap between the free edition and the first paid one is wide: €200 a month

Not checked

The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you

“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.
