What is TestFit?
TestFit is site feasibility software for real estate developers, architects and industrial developers. It generates site plans and building massing from constraints, so teams can test a site and communicate a deal quickly.
TestFit covers parking layouts, 2D and 3D massing, custom unit types and yield studies, with integrations to Revit and SketchUp. Generative design is part of Site Solver and Site Solver Portfolio, while the entry plan Parking Solver focuses on parking studies. Add-ons include Site Intelligence, a pro forma module and an MCP Connection for AI assistants. TestFit is based in Dallas and reports more than 6,200 users, including Prologis and Perkins & Will.
TestFit AI features and use cases
- Generates site plan optionsSite Solver's generative design produces site plans that respect setbacks, parking ratios, unit mixes and other constraints. Developers compare several options in the time a manual test fit would take for one.
- Prompts plans through an AI assistantThe MCP Connection add-on links TestFit to an AI assistant, so users can request and adjust site plans in natural language. This shortens the path from a question in a deal meeting to a plan on screen.
- Adds site and zoning dataSite Intelligence brings environmental and zoning data into the study. Teams spot constraints early and reduce the risk of pursuing a site that cannot carry the planned program.
What sets TestFit apart
- Publishes prices on its website, from $195 per month for the entry plan to $20,000 per year for the portfolio plan.
- Offers an MCP Connection add-on that links site planning to AI assistants.
