TestFit
Automate site plans and accelerate real estate feasibility decisions
By TestFit · HQ Dallas, US · 4.2/5 Value-Position score (estimate)
Positioning guardrails
Best for
- Developers screening many sites who need fast, defensible yield and pro forma answers before spending design fees.
- Architects and planners who must produce multiple concept options quickly to win design fees.
- Contractors and civil engineers who need early quantity takeoffs, parking counts and cut-and-fill insight.
- Parking studies and quick site feasibility where fast 2D/3D massing matters more than design detail.
Ideal size: 3–50 people · Developer, architecture or AEC firm running repeat feasibility studies on standard typologies
Not for
- Firms needing detailed architectural design or BIM authoring — TestFit stops at conceptual massing and hands off to Revit or SketchUp.
- Teams outside the US that depend on local parcel, zoning or environmental data layers.
- Operations-heavy construction teams looking for scheduling, crew management or project controls.
- Firms doing one-off, highly bespoke projects where a single study does not justify an annual subscription.

AI features shipped
TestFit's engine is deterministic; AI enters as an optional MCP connector to the customer's own assistant, which prompts and edits TestFit models in plain language. The vendor states it supplies no model, that prompts stay with the customer and their AI provider, and that it does not train on customer designs.

Bottom line
TestFit is a real estate feasibility platform that turns a site's constraints into editable site plans in minutes rather than weeks. Developers, architects, contractors and civil engineers use it to test zoning, unit mixes and parking ratios, compare schemes, generate quantity takeoffs and tie massing to a live pro forma. Plans push to Revit, AutoCAD, SketchUp, Excel and PDF. Unlimited-user plans start at $195/month for Parking Solver, with Site Solver from $15,000/year.
Frequently asked questions
What does TestFit cost, and how is it licensed?
Parking Solver is $195/month billed monthly and includes unlimited users. Site Solver starts at $15,000/year and Site Solver Portfolio at $20,000/year, both billed annually. Optional add-ons include Site Intelligence (+$150/mo), Pro Forma (+$170/mo) and the MCP Connection (+$100/mo); MCP and Site Intelligence are included in Site Solver. There is no per-seat pricing.
How quickly can a team be productive on TestFit?
Customers report sizing up a site in about 10 minutes where manual studies took days or weeks. Parking Solver is self-serve; Site Solver and Portfolio include dedicated onboarding and an account manager, plus a guided Accelerator library and weekly trainings. Most teams should expect first production use within one to two weeks.
Does TestFit use AI, and what is the MCP connection?
TestFit's design engine is deterministic, not an LLM. The optional MCP Connection lets customers drive TestFit from their own AI assistant (Claude, ChatGPT or similar) in plain language and get back site plans that stay editable in TestFit. Customers bring their own assistant; TestFit states it supplies no model, does not see customer prompts, and does not train on customer designs.
Which design and data tools does TestFit integrate with?
Approved layouts push directly to Revit, and plans export to AutoCAD, SketchUp, Excel and PDF. Pro Forma accepts a customer's own Excel template, and the MCP Connection links TestFit to third-party AI assistants. Revit and SketchUp integration is supported on all plans.
Is TestFit suitable for projects outside the United States?
The core product works globally with the same features. Some data layers — parcel boundaries, flood zones, wetlands, zoning — may not be available in every country. Support and training are currently English-only and staffed during US business hours (9am–5pm CT), which matters for teams that need in-region coverage.
