Testfit
AI site feasibility platform that generates iterative site plans fast for developers, architects, and planners.
TestFit is the fastest way to test site feasibility for real estate deals, cutting study time from weeks to minutes. It's strictly for early-stage planning, not detailed design—if you need construction documentation, stick with Revit. The price is steep (Site Solver starts at $15,000/year), but for teams doing many feasibility studies, it pays for itself. TestFit's strength is its ability to generate and iterate on site plans quickly, with features like generative design, parking automation, and live pro forma linking. It's a must-have for developers and architects who need to vet deals or present multiple options fast. However, the lack of a free tier and high entry cost for advanced

About Testfit
TestFit is a real estate feasibility platform that automates early-stage site planning. Starting from an AI-generated site plan drawn for your parcel, zoning, and program, you can edit down to the last parking stall. It supports multi-family, single-family, industrial, data center, retail, hotel, and parking typologies. Core products include Site Solver for generative design and rapid layout iteration, Parking Solver for automated surface and structured parking layouts, plus add-ons like Site Intelligence (zoning, environmental, utilities data), Pro Forma (live financials tied to the plan), and MCP Connection for prompting the tool with an AI assistant. The platform is built for the deal team—developers vetting acquisitions, architects competing for fees, contractors estimating early costs, and civil engineers checking grading and cut/fill. You can test unit mixes, parking ratios, and zoning scenarios in real time, generate quantity takeoffs for infrastructure and earthwork, and push approved layouts to Revit, AutoCAD, SketchUp, Excel, or PDF. Recent updates (v5.19–v5.23) added flexible parcels, organic subdivisions, a path offset tool, and generative design for retail prototypes, expanding the range of projects you can tackle. With over 6,200 users, TestFit positions itself against CAD-first workflows by compressing feasibility studies from weeks to hours. It excels at concept and feasibility, not construction documentation. Compared to traditional CAD tools, TestFit offers a faster, more iterative approach to site planning, helping you explore more options and make confident decisions early in the process.
Behind the Verdict
TestFit has carved out a clear niche: it's the tool you turn to when you need to know if a piece of land can pencil out—how many units, how many parking spaces, what the grading looks like—before you commit serious capital. It's not a CAD tool, and it doesn't pretend to be. The moment you need construction documents, you're exporting to Revit and moving on. That's by design: TestFit is the feasibility phase, compressed. What makes TestFit genuinely good is the iterative loop. You start with an AI-generated plan based on your parcel and program, then you can tweak parking ratios, unit mixes, or zoning constraints and see the impact on yield and cost in real time. The 3D massing in context is a fast way to communicate a concept to a client or city planner. And for teams who do this all day—like the RBA Architects who credit TestFit with helping win $750k in fees—the speed pays for itself. The weaknesses are more about fit than quality. There's no free tier, so you can't kick the tires without paying. Parking Solver at $195/mo is the entry point, but the really interesting features—generative design, custom unit types, MCP Connection—are locked behind Site Solver at $15,000/year. That's a big jump. Also, TestFit is not for detailed design work; you'll still need Revit or AutoCAD for that. And the pricing page notes that some data layers (like zoning or flood zones) may not be available in all countries, which could be a dealbreaker for international projects. Where does TestFit fit? It's for the deal team—developers vetting acquisitions, architects competing for fees, contractors estimating early costs, and civil engineers checking grading. It's not for hobbyists or small one-off projects where a month subscription may not be justified. And it's not for teams who need a free tool to explore without commitment. In the broader landscape, TestFit's competitors are manual CAD workflows and maybe some new AI site planning tools, but none have the same depth in real estate feasibility. If you're doing many feasibility studies, the ROI is clear. If you're doing a single project, it might be overkill. Our advice: if you're a developer or architect who regularly evaluates sites, the Site Solver tier is worth it. If you're just starting, try Parking Solver for a month to see if the workflow clicks.

Real-world workflow fit
Concrete scenarios for the personas Testfit actually fits — and what changes day-one when you adopt it.
You're evaluating a raw parcel and need to know if it can support a 150-unit multifamily project. You import the parcel boundary, select the multifamily typology, and run Site Solver. In under an hour, you have a site plan with unit mix, parking, and a pro forma linked to it. You test three different unit mixes and see the impact on yield and cost.
Outcome: You confidently move forward with the deal, knowing the financials pencil out, and you have multiple options to present to your investment committee.
A client asks for a feasibility study on a mixed-use site. You use TestFit to generate a massing study, then iterate on parking and unit mix. With the 3D context, you create renderings for the client presentation, showing three different schemes in the context of the surrounding neighborhood.
Outcome: You win the design fee by presenting three viable options in a week, whereas competitors are still waiting for initial drafts.
You're estimating costs for a new data center project. Using TestFit, you lay out the site, and the quantity takeoff feature automatically calculates earthwork, pavement, and infrastructure quantities. You use those numbers to prepare a rough budget for the developer.
Outcome: You provide early cost insights that help the developer assess feasibility, and you position yourself to win the construction contract.
Use Cases
- Quickly evaluate a development site's feasibility and max unit yield.
- Generate multiple design alternatives for client presentations within hours.
- Validate pro forma assumptions against actual building layouts before purchasing land.
