Testfit
AI site feasibility platform for developers, architects, and contractors.
TestFit is the fastest way to test site feasibility, but it's purpose-built for early-stage planning, not detailed design. If you need to vet deals quickly, it's unmatched. For construction-level documentation, stick with Revit.
- Developers quickly vetting deals and focusing capital
- Architects winning design fees with multiple viable options
- Contractors getting early cost insights via quantity takeoffs
- Civil engineers validating cut/fill/grading without manual calculations
- Detailed construction documentation or BIM-level design
- Small-scale or one-off projects where subscription cost isn't justified
- Teams unfamiliar with site planning terminology

Skip TestFit if you need detailed construction documentation or BIM-level design, or if your project budget can't accommodate an annual subscription starting at $2,100.
Advanced generative design and detailed building presets are locked behind the Site Solver tier ($10,000+/year), so teams on lower plans get only basic massing.
TestFit's Parking Solver ($2,100/yr) is affordable for individual parking studies. For full feasibility, Site Solver ($10,000/yr) is pricey but can pay for itself by replacing weeks of manual drafting. Competitors like Archistar and re:3D offer different pricing models, but TestFit's speed and generative design are unique for early-stage site planning.
In short
Testfit — AI site feasibility platform for developers, architects, and contractors. Best for Developers quickly vetting deals and focusing capital, Architects winning design fees with multiple viable options, Contractors getting early cost insights via quantity takeoffs. Plans from $2100/mo.

About Testfit
TestFit is a real estate feasibility platform that automates site planning, enabling developers, architects, and contractors to generate AI-driven site plans in minutes instead of weeks. The platform accelerates decision-making with generative design for site layouts, parking optimization, and instant pro forma validation. Key features include Site Solver for 4x faster planning, Parking Solver for optimal layouts, Site Intelligence for environmental and zoning data, Pro Forma live-link for financial integration, and the new Path Offset Tool introduced in version 5.22 for consistent space creation. TestFit allows you to test zoning, unit mixes, and parking ratios with real-time iteration, and export plans to Revit, AutoCAD, SketchUp, and more. It supports multi-family, single-family, industrial, data center, retail, hotel, and parking typologies. The platform is built for deal teams and has over 6,200 users. TestFit positions itself as a 'generate then edit' tool, emphasizing speed over manual drafting, unlike traditional CAD-first workflows.
Behind the Verdict
TestFit is a niche tool that excels at one thing: rapidly testing site feasibility. If you're a developer or architect evaluating dozens of parcels, it pays for itself in hours saved. The generative design in Site Solver is genuinely impressive, producing optimized layouts you'd never arrive at manually. The Parking Solver add-on is also solid for parking studies. However, the subscription costs are steep — starting at $2,100/year for Parking Solver and $10,000/year for Site Solver — so it's not for occasional use. There's no free tier or pay-as-you-go, which limits access for smaller firms. Compared to traditional CAD plus spreadsheet workflows, TestFit is dramatically faster, but it's not a full BIM or drafting tool. You'll still need Revit or AutoCAD for construction documents. The recent Path Offset Tool (v5.22) and retail generative design (v5.21) show steady improvement, but the core remains early-stage feasibility. Best for deal teams moving fast; skip if you need detailed design or have a limited budget.

Real-world workflow fit
Concrete scenarios for the personas Testfit actually fits — and what changes day-one when you adopt it.
Vetting a new site acquisition opportunity
Outcome: TestFit generates multiple site plans with unit mix and parking options in hours, allowing the developer to compare yield and cost before making an offer.
Presenting design alternatives to a client
Outcome: Using Site Solver, the architect creates 3-4 massing options with pro forma data, winning client approval faster and securing design fees.
Providing early cost estimates for a project
Outcome: TestFit automatically generates quantity takeoffs for parking, earthwork, and infrastructure, giving the contractor accurate cost insights before detailed design.
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.
- Optimize parking layout and cost for a multi-family project.
- Compare zoning and environmental constraints across several candidate sites.
Limitations
Pricing is enterprise-level with Site Solver tier at $10,000+/year; no free plan beyond Urban Planner trial; learning curve for users unfamiliar with site planning workflows; some users may find cost steep for occasional use.

Where the pricing makes sense
The company stage and team size where Testfit's pricing actually pencils out — and where peers do it cheaper.
TestFit's Parking Solver ($2,100/yr) is affordable for individual parking studies. For full feasibility, Site Solver ($10,000/yr) is pricey but can pay for itself by replacing weeks of manual drafting. Competitors like Archistar and re:3D offer different pricing models, but TestFit's speed and generative design are unique for early-stage site planning.
Setup time & first value
How long it actually takes to get something useful out of Testfit — broken out by persona, not the marketing-page minute.
Parking Solver users can generate a basic site layout in under 10 minutes after a brief tutorial. Site Solver with generative design may take a few hours to learn, but first results appear within the first session. Onboarding and training files are available for Site Solver subscribers.
