FlowCraft Scope Estimator
Interactive Estimator Widget
An estimator interface built with HTML, Tailwind CSS, and vanilla JavaScript. Visitors set a project size from 500 to 4,000 sq ft, choose a service package, and the estimated price range updates as they go. No npm install or build step.
Adjust the size and package and watch the range update in your browser. It uses the buyer-delivered widget's default settings.
