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

Most common complaint

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

Three tiers described by features, none of them priced

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.

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.

Scaleflex Three tiers described by features, none of them priced — ask them to answer this in writing before the trial.
