Every property developer, acquisition manager and investor faces the same bottleneck: too many possible sites, not enough hours to assess them properly. Read a planning scheme wrong and a deal that looked like a 20-lot subdivision turns into a heritage headache. Overpay for the land and the whole margin evaporates before you turn a sod. Software should fix both problems — help you find more candidate sites and help you screen them fast enough that only the real contenders reach a paid consultant. Below we compare the tools Australian developers actually shortlist in 2026, what each is best at, and where GoSiteHunt fits.
How we judged each tool
A "development site finder" is not one product category — it is three overlapping ones. Some tools are strongest at discovery (surfacing sites you did not know existed). Some are strongest at planning intelligence (zoning, overlays, controls, what you can build). Some are strongest at feasibility (residual land value, cashflow, GO/NO-GO). The best fit depends on which of those jobs is your real bottleneck. We looked at four things:
Address-level due diligence
Can the tool turn a raw address into parcel, zoning, controls, constraints and early feasibility without days of manual checking?
Residual land value
Does it set the maximum land price from end value, cost, margin and finance — or leave you guessing what to offer?
Discovery and coverage
Can it find candidate sites by area and type, and does it work where you actually operate — one country, or many?
Speed and price
Can a small team screen dozens of deals a week without an enterprise contract and a long onboarding?
The tools, honestly compared
Archistar
Archistar is one of the strongest Australia-native platforms. It covers all eight states and territories with deep planning data and its standout feature is automated, planning-compliant 3D massing: point it at an address and it generates buildable design options with area schedules and yield figures, plus automated feasibility reports. If your job is to answer "what can I actually build here, and roughly how much of it," Archistar is genuinely excellent and hard to beat on design automation. It sits toward the premium end on price once you move past the free exploration tier, and its depth is Australia-first rather than global.
Landchecker
Landchecker is a clean, data-rich mapping and property-report platform covering most of Australia. Its planning maps, boundary data, overlays and high-resolution imagery are a favourite of agents, surveyors and developers who want reliable due-diligence data in one place. Where Landchecker is genuinely better: layered planning maps and property reports as a research surface. It is less about automated feasibility or a GO/NO-GO decision and more about giving you trustworthy raw data to interpret yourself. There is a free tier, with paid plans and premium reports for professional teams.
Deepblocks
Deepblocks is an AI-driven zoning and feasibility platform built primarily for the United States, with digitised zoning across 200+ cities, a GIS-style interface layering demographics and market data, and a 3D modeller with financial analysis. For US acquisition teams filtering thousands of parcels, it is a serious tool and arguably better than GoSiteHunt inside its home market's data depth. For Australian developers it is the weakest fit here on coverage — its strength is US zoning data, not Australian planning schemes.
Aprao
Aprao is a cloud appraisal and feasibility platform built primarily for UK developers, valuers and lenders. It excels at exactly one thing and does it very well: building a data-rich development appraisal in minutes, solving residual land value in real time, forecasting cashflows, modelling development finance and stress-testing assumptions, then exporting a lender-ready report. If deep, auditable, finance-grade feasibility is your bottleneck, Aprao is genuinely better than GoSiteHunt at appraisal rigour. What it deliberately does not do is find sites or read planning controls — you bring the deal, it models it.
LandTech (LandInsight)
LandTech's LandInsight is the long-established UK incumbent for site sourcing. Its strength is ownership data from HM Land Registry and Companies House, planning-application history and alerts, and off-market outreach — helping teams find and assess UK sites dramatically faster. For finding off-market land and identifying who owns it in the UK, LandTech is genuinely better than GoSiteHunt. Its coverage, however, is UK-focused, so it is not the tool for Australian or cross-border pipelines.
GoSiteHunt
GoSiteHunt is built for developers who want one instant, affordable workflow that runs the whole loop — find, feasibility, maximum land price, GO/NO-GO — and who work across more than one country. For any address in 35+ countries (including all of Australia) it returns in seconds: zoning and what you can build, dwelling and lot yield, development feasibility, residual land value (the most you should pay for the land), and a plain GO/NO-GO screen. It also finds candidate sites by suburb and type — greenfield subdivision, townhouses, apartments, mixed-use, retail, billboards and energy or data-centre land — scans whole areas, checks subdivision potential, and watches development applications near an address. Where GoSiteHunt does not try to win: it is not a finance-grade appraisal engine like Aprao, nor a 3D massing generator like Archistar. It is a fast, broad screening layer that sits before those specialist tools.

Which one should you pick?
Match the tool to your real bottleneck, not to a feature checklist:
Choose Archistar for automated, planning-compliant 3D massing and yield in Australia. Nothing here matches its design automation.
Choose Landchecker for the best Australian planning maps, overlays and property reports to interpret yourself.
Choose Aprao (UK) for auditable residual land value, cashflow and lender-ready feasibility depth.
Choose GoSiteHunt to find, screen and price sites across 35+ countries before you pay a specialist.
Plenty of serious teams run two of these together — GoSiteHunt to sift the pipeline fast and cheaply, then Archistar or Aprao to go deep on the two or three deals that survive the screen.

Frequently asked questions
What is the best development site finder software in Australia for 2026?
There is no single winner for every team. Archistar and Landchecker are strong Australia-native choices for planning data and compliant massing. Aprao and LandTech lead in the UK for appraisal and site sourcing, and Deepblocks is US-focused. GoSiteHunt suits developers who want one instant, affordable, end-to-end workflow that finds sites, checks zoning and yield, calculates residual land value and gives a GO or NO-GO screen across 35+ countries.
Does GoSiteHunt cover the whole of Australia and other countries?
Yes. GoSiteHunt returns an instant site report for any address across 35+ countries, including all of Australia. Most competitors are single-country: Archistar and Landchecker are Australia-focused, Aprao and LandTech are UK-focused, and Deepblocks is US-focused.
How much does development site finder software cost?
GoSiteHunt is free to start with 50 trial credits, where a site report is one credit and an area scan is five. Paid add-ons are priced per product from a $49 vendor's report through to $499/mo Operator plans. Several rivals aimed at agencies and enterprise teams sit at premium or enterprise price points, so always check current pricing on each vendor's own site.
What is residual land value and why does it matter?
Residual land value is the most you should pay for a site once you subtract construction, professional fees, finance, contingency and your target profit from the projected end value. GoSiteHunt calculates it instantly so your offer follows the numbers instead of emotion. You can also try the free residual land value calculator or read the step-by-step guide.
Can these tools tell me how many townhouses or lots fit on a site?
Archistar generates compliant 3D massing options and yield figures. GoSiteHunt estimates dwelling and lot yield from an address and offers dedicated checks for subdivision potential and how many townhouses fit, as indicative screening before you engage a planner or surveyor.
Is GoSiteHunt a replacement for a planner, valuer or surveyor?
No. GoSiteHunt outputs are indicative screening only, not valuation, planning, financial or legal advice. Use them to sift deals quickly, then confirm the shortlist with qualified professionals before you commit. See how it works and the full FAQ for detail.
Which tool is best for finding off-market development sites?
LandTech is strong for UK ownership data and off-market outreach. In Australia and beyond, GoSiteHunt finds candidate sites by suburb and development type, watches development applications near an address, and lets owners list off-market directly to developers with no agent and no commission.
Screen your next site in seconds
Stop losing weekends to manual zoning checks and stop paying consultants on deals that were never going to work. Run an address, see the zoning, yield, residual land value and a clear GO/NO-GO, then take only the survivors forward.
