Research reviewed October 2026. This is a research-based review — we analyzed published specs, pricing, and user feedback.

Quick verdict

✓ Best for:Developers, architects and GCs in pre-design who evaluate sites and deals continuously and need defensible yield and cost answers in hours, not weeks – especially multifamily and mixed-use teams where parking and unit mix drive the deal.

✕ Skip it if:Firms that run one or two feasibility studies a year: at Site Solver money, occasional studies are cheaper bought from an architect. Also skip if your work is heavy civil or industrial – TestFit's solvers are building-focused.

Bottom line:TestFit is the feasibility tool to beat: fast solvers wired directly to the pro forma, at published prices. If deal evaluation is a weekly activity in your shop, run your next site through it and compare the hours.

TestFit Review 2026: Generative Feasibility With Published Pricing

Updated October 13, 2026 – Tested Intelligence

Quick verdict: TestFit generates and solves site, building and parking layouts in real time, optimising unit mix, yield and the pro forma against zoning and parking constraints, with automatic quantity takeoff and costing and exports to Revit, SketchUp and AutoCAD. Developers, architects and GCs use it to kill bad deals fast and price good ones earlier. The vendor cites 3,200+ deals evaluated per week – and publishes its pricing: Parking Solver at $195 per month, Site Solver from $15,000 per year, Portfolio from $20,000 per year.

What it is

Feasibility is a numbers game played under time pressure: a site appears, and the team has days to decide whether the deal works. TestFit’s solvers generate building and parking configurations that respect zoning and parking constraints, then optimise the things the pro forma cares about – unit mix, yield, efficiency – while producing quantities and costing as it goes, so the financial answer arrives with the drawing, not a week after it.

Speed changes the decision quality. When each scheme takes minutes instead of days, teams test more options, walk away from marginal deals earlier, and negotiate land with evidence. TestFit exports to Revit, SketchUp and AutoCAD so a winning scheme continues into design instead of being redrawn. The vendor’s claim of 3,200+ deals evaluated weekly on its retail page suggests this is now standard practice for a large slice of the development market rather than an experiment.

Key features

Real-time site, building and parking solvers
Optimises unit mix, yield and pro forma against zoning and parking constraints
Automatic quantity takeoff and costing generated with each scheme
Exports to Revit, SketchUp and AutoCAD
Vendor cites 3,200+ deals evaluated per week
Published pricing: Parking Solver $195/mo; Site Solver from $15,000/yr; Portfolio from $20,000/yr; add-ons $100-$170/mo

Pricing

TestFit publishes its pricing – a rarity in this roundup. Per the vendor’s pricing page: Parking Solver is $195 per month; Site Solver starts at $15,000 per year; Portfolio starts at $20,000 per year; add-ons run $100 to $170 per month. That transparency makes the buying test simple: how many feasibility studies does your team run a year, and what does each one currently cost in architect and analyst hours?

Who it’s for

Developers, architects and GCs in pre-design who evaluate sites and deals continuously and need defensible yield and cost answers in hours, not weeks – especially multifamily and mixed-use teams where parking and unit mix drive the deal.

Who should skip it

Firms that run one or two feasibility studies a year: at Site Solver money, occasional studies are cheaper bought from an architect. Also skip if your work is heavy civil or industrial – TestFit’s solvers are building-focused.

Pros

Published, specific pricing – no quote games
Solvers optimise the financial variables (mix, yield, pro forma), not just geometry
Quantities and costing generated with the scheme
Proven throughput: vendor cites 3,200+ deals evaluated weekly

Cons

Site Solver money ($15,000/yr+) needs a steady deal pipeline to justify
Building-focused: not a civil or infrastructure feasibility tool
Solver output still needs zoning and market judgement – it optimises inputs you give it
Pro forma quality depends on your cost and rent assumptions
