A must-try for real estate developers and architects who need rapid feasibility studies. It slashes initial drafting time from weeks to minutes and supports multiple typologies. Pricing starts at $175/month for Parking Solver or $10,000/year for Site Solver, so contact sales for enterprise. If you need full BIM authoring, pair it with Revit.

TestFit stands out for its ability to generate site plans and feasibility studies in minutes, a process that traditionally takes weeks. The generative design engine allows you to iterate on unit mixes, parking ratios, and building layouts rapidly, with 3D context for stakeholder presentations. Its strength is in early-stage deal evaluation: you can vet multiple sites quickly and validate pro forma assumptions before committing capital. However, TestFit is not a full CAD or BIM tool — you'll still need Revit, AutoCAD, or SketchUp for detailed documentation. Pricing is not transparent for the Site Solver tier beyond a $10,000/year starting point, and there's no free tier beyond the Urban Planner trial. The learning curve is moderate for those new to site planning workflows. Best for medium-to-large real estate firms, architecture practices, and contractors with a steady volume of projects. Small firms or low-volume users may find the cost hard to justify.

How likely is Testfit to still be operational in 12 months? Based on 6 signals including funding, development activity, and platform risk.
TestFit is a real estate feasibility platform that automates site planning and accelerates decisions for developers, architects, contractors, civil engineers, urban planners, municipalities, and brokers. It generates AI-driven site plans that can be edited down to the last parking stall. Key features include generative design for rapid site layout (4x faster), parking layout optimization, site intelligence to reduce risk with environmental and zoning data, real-time deal prototyping, and automatic takeoffs for parking, infrastructure, and earthwork. Integrations include direct export to Revit, AutoCAD, SketchUp, Excel, and PDF. Unlike traditional manual processes, TestFit enables users to size up a site in minutes rather than weeks, with 3D context for faster approvals and financial validation against pro formas. TestFit offers three pricing tiers: Parking Solver at $175/month (billed annually) for parking studies, Site Solver starting at $10,000/year for full feasibility, and Site Solver Portfolio starting at $15,000/year for portfolio-scale evaluation.
Concrete scenarios for the personas Testfit actually fits — and what changes day-one when you adopt it.
You have a list of 10 potential sites to evaluate this week.
Outcome: You import parcel boundaries, set unit mix and parking ratios, and generate AI site plans in minutes. Compare pro formas for each site and shortlist the top 3 for further due diligence.
Client requests multiple design options for a mixed-use project.
Outcome: You generate 5-10 site plan alternatives with different unit counts and parking layouts. Present 3D massing in context during the client meeting, secure approval, and export the chosen layout to Revit for documentation.
You need to assess cut/fill costs for a proposed development before bidding.
Outcome: Using Site Intelligence, you import 3D terrain data and get automatic earthwork takeoffs. Adjust building pads and road grades, then export quantity reports to Excel for cost estimation.
No free plan beyond the Urban Planner trial; advanced generative design features require the Site Solver tier ($10,000+/year); limited to certain typologies (effectively excludes custom non-building site types); learning curve for users not familiar with site planning workflows; some users may find the pricing steep for occasional use.

Parking Solver
$175/mo
Ideal for
Civil engineers and parking consultants needing fast surface and structured parking layouts with 2D/3D massing.
What this tier adds
Starting tier at $175/month billed annually; focused on parking automation and yield estimation only.
Site Solver
$10,000/yr
Ideal for
Developers and architects who need full generative design, detailed typology presets, and dedicated account manager.
What this tier adds
Adds generative design, subdivision/parcels, custom unit types, and priority support over Parking Solver.
Site Solver Portfolio
$15,000/yr
Ideal for
Enterprise real estate firms and portfolio managers running volume deals with need for SSO and quarterly business reviews.
What this tier adds
The company stage and team size where Testfit's pricing actually pencils out — and where peers do it cheaper.
TestFit's pricing fits mid-to-large real estate firms and architecture practices with steady project volume. Parking Solver at $175/month is accessible for parking studies, but full feasibility requires Site Solver at $10,000+/year. Cheaper alternatives include manual CAD workflows (labor-intensive) or Archistar (for Australian market); more expensive peers like Autodesk Forma offer broader BIM integration.
