The models' case: Best all-around choice for a startup building a substantial web SaaS product: unusually deep visual logic, integrated database and hosting, mature plugin ecosystem,…. The models' main caveat: Proprietary runtime, workload-based costs, and no source-code export create serious lock-in as an app scales..
