Our assessment in one line
A narrow, competent product with an awkward price. Stacker does per-client permissions over an existing data source better than most, and the portals look respectable without design work. But it starts at 59 EUR with no free tier, the AI layer is thin, and Softr now does a broadly similar job for less. Worth a look if the permission model is genuinely the hard part of your problem. Otherwise there are cheaper routes to the same portal.
