Every acquisition team wastes time on the same thing: chasing sites that were never going to work. You find a listing, pull up the planning scheme, guess the yield, back-of-envelope a margin, and only weeks later discover the overlay, the flood layer, or the price that kills it. The payoff of good software is not prettier reports — it is killing bad deals in minutes instead of weeks, and pricing the good ones before someone else does. The six tools below all attack that problem, but from different ends of it: some start with maps and planning data, some start with the pro forma, and some try to do the whole chain from finding a site to a GO/NO-GO call. Below we rank them by fit, name where each is genuinely the better choice, and show where GoSiteHunt sits.
How we compare feasibility tools
"Best" is meaningless without a job to do. A UK developer refinancing a build-to-rent scheme with a lender needs different software from an Australian acquisition manager scanning fifty suburbs for a townhouse site, or a US investor screening parcels across state lines. We score each tool on five capabilities that actually move a deal forward:
Site finding
Does it find candidate sites by suburb and type, or only analyse an address you already have?
Planning & zoning depth
Zoning, overlays, controls, precedent — how reliable and how current is the planning layer?
Feasibility & residual land value
Does it model the numbers and tell you the most you should pay for the land?
Coverage
One country, one city set, or many markets? This is where tools diverge hardest.
Speed & price to entry
Instant and self-serve, or an enterprise contract and onboarding call before you see an answer?
The comparison at a glance
The table is a screening view, not a scorecard war. Read it by the column that matters to your role. Prices are described qualitatively where a vendor does not publish them on their own site; do not treat "premium/enterprise" as a criticism — those tools are often worth it for the teams they target.
| Tool | Core strength | Finds sites? | Residual land value | Coverage (2026) | Entry |
|---|---|---|---|---|---|
| GoSiteHunt | End-to-end: find → feasibility → max land price → GO/NO-GO | Yes, by suburb & type | Yes, headline output | Global (35+ countries) | Free to start, 50 trial credits |
| Archistar | AI site discovery + 3D massing + compliance PreCheck | Yes | Feasibility & ROI modelling | Australia, Canada, US | Subscription (no public price) |
| Landchecker | Best-in-class AU planning maps, zoning & imagery | Search/filter, not deal-scan | Not a feasibility engine | Australia only | Free tier, paid plans |
| Deepblocks | Zoning analytics + pro forma across many US cities | Yes (parcel filtering) | Yes, pro forma driven | US-focused (200+ cities) | Developer access from a monthly fee |
| Aprao | Deepest development appraisal, RLV, cashflow & finance | No — you bring the scheme | Yes, real-time, lender-grade | UK-centric | Subscription (enterprise-grade) |
| LandTech (LandInsight) | UK site sourcing, planning data & appraisal in one | Yes, strong in the UK | Appraisal included | UK | Tiered plans (Starter → Pro) |
Archistar — best for AU/Canada/US teams who want 3D massing and compliance
Archistar is the most complete of the map-first platforms in the markets it covers (Australia, Canada and the US). Its stand-out is generative design: point it at an address and it produces compliant 3D massing options against setbacks, height and overlays, plus an "AI PreCheck" compliance layer and an automated feasibility/ROI calculator. If your workflow depends on visualising what fits on a site and running planning compliance before you commission an architect, Archistar is genuinely strong and hard to beat on that axis. Where it is less suited: it is enterprise-oriented, does not publish pricing on its own site, and its coverage is limited to three countries — so a team looking across Europe, Asia or emerging markets will hit its edges. Archistar wins the "3D + compliance" use case outright.
Landchecker — best for Australian planning research
Landchecker is not really a feasibility engine, and it doesn't pretend to be. What it is: the cleanest way to interrogate Australian planning data — daily-updated zoning, overlays, planning maps and very high-resolution aerial imagery — with a genuinely free forever Starter tier for a single user. For an Australian town planner, buyer's agent or developer who lives in zoning maps and property reports, Landchecker is excellent and often the best day-to-day research tool on this list. Its limits are deliberate: it is Australia-only, and it stops short of modelling yield, running a residual land value, or giving you a GO/NO-GO. It answers "what are the controls here?" superbly, then hands the feasibility question to you.
Deepblocks — best for US developers filtering parcels at scale
Deepblocks pairs digitised zoning with pro forma and demographic data so you can filter thousands of parcels and generate feasibility across 200-plus cities. It is genuinely powerful for a US national or regional developer without boots on the ground in every market, and it publishes tiered deal-flow plans (developer access starts at a modest monthly fee, with higher tiers that surface curated opportunities). If your beachhead is the United States and you want algorithmic parcel filtering plus modelling, Deepblocks is a strong pick and better than GoSiteHunt for deep US-specific zoning analytics. Outside the US, though, its coverage falls away — its own case studies are Miami-centric — so it is not the tool for a global or multi-country pipeline.
Aprao — best for lender-grade UK development appraisals
Aprao is the specialist here, and on its chosen ground it is the best of the six. It builds data-rich development appraisals in minutes, solves residual land value in real time, forecasts cashflow, models development finance from simple facilities to complex structures, and stress-tests assumptions with sensitivity analysis — all to an auditable, lender-ready standard (ISO 27001, GDPR). For a UK developer, valuer or lender who needs an appraisal that will stand up in front of a credit committee, Aprao beats everything on this list, GoSiteHunt included. What it deliberately does not do: it doesn't find sites for you, and it is UK-centric. You bring the scheme; Aprao makes the numbers bulletproof.
LandTech (LandInsight) — best for UK site sourcing
LandTech's LandInsight is trusted by thousands of UK developers and brings sourcing, assessment and appraisal into one workflow — opportunity mapping, ownership data, constraints, planning history and precedent analysis, with the promise of finding and assessing sites materially faster. For a UK team whose bottleneck is finding the next site and understanding its planning context, LandInsight is a category leader, with tiered plans from Starter to Pro. Like the other specialists, its strength is also its boundary: it is UK-only. If your market is Britain, it and Aprao together cover the two ends of the deal — LandTech to source and screen, Aprao to appraise.
Where GoSiteHunt fits
GoSiteHunt is not trying to out-massing Archistar, out-plan Landchecker, or out-appraise Aprao in the UK. It is built for a different shape of problem: global, end-to-end, instant early-stage screening. For any address across 70-plus countries it returns, in seconds, the zoning and what you can build, the dwelling and lot yield, a development feasibility, the residual land value — the most you should pay for the land — and a plain GO/NO-GO screen. Then it does the thing most of these tools don't: it finds candidate sites for you by suburb and type (greenfield subdivision, townhouses, apartments, mixed-use, retail and bulky-goods, billboards, and energy or data-centre land), scans whole areas, checks subdivision potential, and watches development applications near an address. There is also an owner side — what's my site worth, and selling off-market direct to developers with no agent and no commission, including sell-together amalgamation.
The trade-off is honest: GoSiteHunt is a fast, affordable screening layer that covers the whole chain in many markets, where the specialists go deeper in one country or one function. Use it to decide which deals deserve a full Aprao appraisal, an Archistar massing study or a Landchecker planning deep-dive. Start these where it helps:

Which one should you choose?
Short version. If you're a UK developer, pair LandTech to source with Aprao to appraise. If you live in Australian planning data, Landchecker is your daily driver, with Archistar when you need 3D and compliance. If you're a US parcel-filtering shop, look hard at Deepblocks. And if you work across more than one market, or you want one instant, affordable tool to find, screen, price and GO/NO-GO before you invest in a heavier study, that's the gap GoSiteHunt is built for. Many teams run GoSiteHunt at the top of the funnel and a specialist at the bottom — the two are complements, not rivals.
Screening outputs across all of these tools — GoSiteHunt included — are indicative only. They are not valuation, planning, financial or legal advice. Always confirm planning controls, market evidence and build costs with the relevant authorities and your own advisers before committing to a site.
Frequently asked questions
- What is the best property development feasibility software in 2026?
- There isn't a single winner — it depends on your market and the job. Aprao is best for lender-grade UK appraisals, LandTech for UK site sourcing, Landchecker for Australian planning research, Archistar for 3D massing and compliance in AU/Canada/US, and Deepblocks for US parcel filtering. GoSiteHunt is the best fit if you want one global, instant, affordable tool that finds sites and runs feasibility, residual land value and a GO/NO-GO end to end.
- Which tool actually finds development sites, not just analyses an address?
- GoSiteHunt, Archistar, Deepblocks and LandTech all include site discovery. Landchecker offers search and filtering rather than deal-scanning, and Aprao is an appraisal tool — you bring the scheme to it. GoSiteHunt lets you scan whole suburbs by development type and returns ranked candidates.
- Do any of these work outside Australia, the UK or the US?
- Coverage is where these tools diverge most. Landchecker is Australia-only; Aprao and LandTech are UK-centric; Deepblocks is US-focused; Archistar spans Australia, Canada and the US. GoSiteHunt covers 70-plus countries, which is its main reason to exist for cross-border teams.
- How much does GoSiteHunt cost?
- You can start free with 50 trial credits — a site report costs 1 credit and an area scan 5. Separate paid products include a $49 vendor's report, Deal Flow alerts from $49/mo, a DocFlow planning report ($249 instant or $990 planner-reviewed), White-label at $99/mo, Assembly Pro at $299/mo, and Billboard or Energy Operator plans at $499/mo each.
- What is residual land value and why does it matter?
- Residual land value is the most you can pay for the land and still hit your target profit, after build costs, fees, finance and margin. It's the number that stops you overpaying. GoSiteHunt returns it as a headline output; you can also work through it with the RLV calculator and the how-to-calculate guide.
- Can I use GoSiteHunt alongside Aprao, Archistar or Landchecker?
- Yes, and many teams do. GoSiteHunt works well as the top-of-funnel screening layer — find, price and GO/NO-GO fast — then hand the survivors to a specialist for a lender-grade appraisal, a 3D massing study or a deep planning review.
- Are GoSiteHunt's numbers a valuation I can rely on?
- No. Every output is indicative screening to help you decide what's worth a closer look. It is not valuation, planning, financial or legal advice. Confirm controls, comparable evidence and costs with the relevant authorities and your advisers before committing.
