Pool Studio (Structure Studios) Alternatives (Real Limits Compared)
Pool Studio (Structure Studios) is a solid choice, but people look for alternatives because of the fine print: No free tier at all; only a 30-day free trial, after which Pool Studio is $147 per user/month (VIP3D $197) plus a one-time $95 setup fee. On top of that, no free tier beyond a 30-day trial. Strong options to compare include Pool Planner AI and Latham Liner Visualizer. Below we line up the real free limits of each — what it exports, what it watermarks, and which platforms it runs on — so you switch for the right reason.
