ResourceSpace, PhotoShelter, ImageKit, Optimizely

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

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.

A cloud portfolio and image-storage platform for individual photographers, with client galleries and built-in print/licensing sales.

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 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.

Billed on

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

Quote-only. Priced per named "Library Seat" (2-5 seats depending on tier, custom for Enterprise) plus a storage allotment per tier (1TB-5TB, custom for Enterprise) and a cap on "Advanced Integrations" (0 to unlimited). Unlimited invited/contributor users and unlimited Social Content Publisher seats included on all/most tiers. Annual or monthly billing toggle shown on the pricing page, but no dollar amounts are published — all tiers show a "Get Pricing" CTA to a demo/sales call.

Most common complaint

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

Not checked

Several units are metered at once: bandwidth, storage, video units and seats

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.

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

Optimizely Not one tier and not one figure on the pricing page — ask them to answer this in writing before the trial.
