TestFit vs Arcol

Two browser-era tools for early site and building feasibility, so this is partly like-for-like. TestFit is a real estate feasibility platform that generates editable site plans with parking, massing, a synced pro forma and earthwork takeoffs. Arcol is a browser-based building design platform where a parametric model, live metrics, a pro forma and presentation boards update together. Desk research from vendor sites read Nov 1, 2026; no winner.

What it doesReal estate feasibility platform built on what the vendor calls an editable AI-generated site plan (editable down to the last parking stall), with massing, a pro forma and takeoffs. Features listed: parcel mapping, road layout, turning radii, topography, parking automation, 2D/3D massing, a pro forma synced to the layout, and automatic takeoffs for parking, infrastructure and earthwork (including cut and fill). Products are Site Solver and Parking Solver, with Site Intelligence (site, environmental and zoning data), Pro Forma and an MCP Connection ("prompt your site plans with an AI assistant") as add-ons; the menu features the TestFit 5.26 release. Generative design is only on Site Solver; Revit and SketchUp integration is on all plans; exports go to Revit, AutoCAD, SketchUp, Excel and PDF. The Data Center typology page describes generative design bounded by minimum and maximum megawatt limits, parameters such as target power density, design PUE and yard depths, regional power plant data, multi-level infill data centers with data halls, electrical rooms and mechanical yards, and phased campus layouts with roads and substations. The pricing FAQ says some data layers (parcel, flood zone, wetland, zoning) may not be available in all countries, Site Solver subscribers get a dedicated account manager, and support is English-only during U.S. business hours (9:00 AM-5:00 PM CST). User counts, customer-survey ROI figures, speed multipliers and customer quotes are vendor material not used here.Browser-based building design platform where a parametric model, live metrics, a pro forma and presentation boards update together. The homepage headline is "Build something real." and says Arcol is the easiest way to blend design intent and construction reality. Product pages: Modeling (a parametric modeler with lofts and booleans; masses divided into floors and floor plans for metrics; one live model that designers, builders and owners share), Metrics (site and building metrics update as you edit; enter material and building-system costs to see project financials), Boards (live-updating sheet sets shared by one link) and Collaboration (multiplayer editing, comments in context, link sharing). Team pages add parcel search with zoning data through a Zoneomics integration, generative design of parametric buildings and parking, design options, a live pro forma that recalculates as the model changes, and Excel integration for tables and quantities; the General Contractors page pitches bringing cost and construction constraints into the first drawing. The plan comparison lists unlimited collaborators, live-updating metrics, sheet sets and automatic site context, with Revit export and North American parcel and zoning data on paid plans. The pricing FAQ says editors can create presentations, change metrics and model while collaborators can view and comment, team admins manage billing from their settings page, and student offers are available through sales. Customer stories and quotes are vendor material and are not used.
Who it's forDevelopers, architects, contractors, and civil engineers on the deal team.Architects and designers, developers, general contractors and owners (vendor's site navigation lists all four).
Pricing (as publicly stated)Parking Solver $195/month billed monthly (unlimited users), with optional add-ons: Site Intelligence +$150/mo (zoning and environmental data, 3D terrain with cut and fill analysis, power and utilities infrastructure), Pro Forma +$170/mo and MCP Connection +$100/mo. Site Solver from $15,000/year billed annually (includes Parking Solver plus generative design, MCP Connection, Site Intelligence, custom unit types, high-detail building presets and a dedicated onboarding and account manager; Pro Forma optional). Site Solver Portfolio from $20,000/year (adds volume pricing, enterprise SSO and quarterly business reviews).Solo: free for personal projects, no credit card required. Team: $100 per user per month billed monthly (unlimited projects, templates, Revit export, North American parcel and zoning data, customer success manager). Team Annual appears in the comparison table without a separate price, through Contact Sales. Confirm current pricing with the vendor.

Where the vendor descriptions differ

  • Partly like-for-like: both target the feasibility stage and both tie a live pro forma to the design. TestFit centres on site layout (parcels, roads, parking, topography and cut and fill). Arcol centres on authoring the building itself (parametric massing divided into floors and floor plans) with shared boards and sheet sets.
  • Generative design (vendor statements): TestFit lists generative design on its Site Solver plan, plus parking automation and typology pages such as data centers bounded by megawatt limits and power density. Arcol's Developers page says it creates fully parametric buildings and parking in a few clicks.
  • Site data: TestFit's Site Intelligence add-on covers site, environmental and zoning data, 3D terrain with cut and fill analysis, and power and utilities infrastructure; its FAQ says some data layers may not be available in every country. Arcol lists North American parcel and zoning data on paid plans and says zoning comes through a Zoneomics integration.
  • Quantities and cost: TestFit lists automatic takeoffs for parking, infrastructure and earthwork and an optional Pro Forma synced to the layout. Arcol says you enter material and building systems costs, its live pro forma recalculates as the model changes, and tables and quantities can connect to Excel.
  • Collaboration and output: Arcol runs in the browser with multiplayer editing, comments in context, link sharing and boards that turn the model into live-updating sheet sets, with Revit export on paid plans. TestFit lists Revit and SketchUp integration on all plans and exports to Revit, AutoCAD, SketchUp, Excel and PDF, plus an MCP Connection to prompt site plans from an AI assistant.
  • Audience: TestFit names developers, architects, contractors and civil engineers on the deal team. Arcol's navigation names architects and designers, developers, general contractors and owners; its General Contractors page pitches cost and construction input from the first drawing.
  • Pricing (vendor pages read Nov 1, 2026): TestFit lists Parking Solver at $195 per month (unlimited users) with paid add-ons, Site Solver from $15,000 per year and Site Solver Portfolio from $20,000 per year. Arcol lists a free Solo plan for personal projects and Team at $100 per user per month billed monthly, with annual terms through sales.
  • Not used here: TestFit's survey ROI figures, speed multipliers and customer quotes, and Arcol's customer quotes and customer-story results (vendor material). Facts for both come from vendor websites (desk research).

What users say

The facts above come from vendor websites. Whether either tool is any good for your work is something only people who use them can say. These are member reviews, all ratings shown, never edited or removed for being negative.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • Whether your feasibility work is mostly site layout and parking yield or building massing and floor plans, which changes which tool fits
  • How each tool's pro forma and quantities compare with your own early estimate on a site you know
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
  • Where does it fall short, and what would make you switch?
