Can it find sites?
A ranking engine should surface opportunities across a whole suburb or postcode, not only score an address you already typed in. Discovery is where most tools quietly stop.
If you have landed here, you are probably weighing Deepblocks against other property-development feasibility platforms and asking a practical question: which tool actually fits my deals, in my markets, at a price my pipeline can justify? Choosing the wrong platform is expensive twice over. You pay the subscription, and you pay in missed deals while your competitors screen faster than you do. This page compares Deepblocks with the strongest 2026 alternatives, names where each is genuinely better, and shows where GoSiteHunt fits.
What Deepblocks does well
Credit where it is due. Deepblocks pioneered the idea of digitising municipal zoning codes and applying them at the parcel level, then wiring that straight into an early financial pro-forma. Its core product turns a US address into a zoning-compliant 3D massing model, calculates the allowable building envelope, and lets you flex development or value-add scenarios with return metrics attached. For a developer working a Miami, New York, Los Angeles or other covered-city infill deal, that combination of interactive massing plus integrated financials in one screen is genuinely useful. Deepblocks also publishes transparent, tiered monthly pricing, which is refreshing in a category full of "contact sales" quotes.
The honest caveats are three. First, coverage is US-focused and city-by-city: Deepblocks has spent years digitising zoning across a few hundred US cities, but its deep zoning intelligence stops at its coverage map, and adding a city's zoning layer sits in a premium tier. Second, it is primarily an analysis tool for parcels you already know about, not a discovery engine that hands you a ranked list of sites you had never heard of. Third, once you move past the entry tier into real zoning intelligence and deal flow, pricing climbs into enterprise territory. None of that makes Deepblocks bad. It makes it a specialist. Whether it is the right specialist depends on where you build and what job you are hiring the software to do.
How to compare property-development tools
Before the table, three questions separate the contenders. Get these right and the shortlist chooses itself.
Can it price the land?
Residual land value is the bridge between planning potential and a real offer. If a tool tells you what you can build but not the most you should pay, you are still doing the hard part by hand.
Does it fit your geography and budget?
A brilliant tool that does not cover your country, or that costs more per month than your first deal will earn, is the wrong tool. Coverage and price are features, not footnotes.
Deepblocks alternatives compared
The table below is a screening comparison, not a scorecard. We have verified each competitor's current positioning on their own site before writing. Prices move, so where we could not confirm an exact figure we describe the pricing model qualitatively rather than guess.
| Tool | Primary job | Finds sites? | Residual land value | Geography | Pricing model |
|---|---|---|---|---|---|
| GoSiteHunt | Find → feasibility → max land price → GO/NO-GO, end to end | Yes — by suburb and product type | Yes — headline output | Global (35+ countries) | Free 50 trial credits; low-cost paid add-ons |
| Deepblocks | Parcel zoning, 3D massing and integrated financial modelling | Deal-flow tier only | Financial pro-forma (not a standalone RLV screen) | US, city-by-city coverage | Tiered monthly; scales to enterprise |
| TestFit | Rapid site-plan and building layout solving | No — you bring the site | No — design/yield focus | Geography-agnostic (you supply rules) | Subscription / enterprise |
| Archistar | Zoning, envelope and generative design | Partial (rules-based search) | Limited | Strong AU coverage; expanding | Premium / enterprise pricing |
| Spreadsheet + council portals | Whatever you build yourself | No | Only if you model it | Anywhere, manually | Free, but slow and error-prone |

Where each alternative genuinely wins
Deepblocks wins when you work inside its covered US cities and want 3D massing wired directly into a detailed financial model on the same screen. Its zoning digitisation in those markets is deep, and for scheme-shaping and investor-grade pro-formas on a known parcel it is a serious tool.
TestFit wins on architectural site-planning. If your bottleneck is "how many units and what layout actually fit on this specific pad, and how does parking work," TestFit's real-time solver is built for that job in a way a screening tool is not. It assumes you already have the site.
Archistar wins for teams that want generative design plus envelope testing, with genuinely strong Australian coverage. If your workflow is design-led and you want the software to propose massing options, it earns its place.
GoSiteHunt wins when your bottleneck is earlier and broader: which sites are even worth analysing, anywhere in the world, and what is the most I should pay? We are not a 3D massing studio and we do not pretend to be. We are the fast top-of-funnel filter that tells you which deals deserve the deep tools above, and which to kill before you waste a day on them.
How GoSiteHunt helps
GoSiteHunt is instant property-development feasibility and site-finding software. For any address across 35+ countries it returns, in seconds: the zoning and what you can build, the likely dwelling or lot yield, a development feasibility read, the residual land value (the most you should pay for the land), and a plain GO / NO-GO screen. That is the whole point of the platform — not a scenario you assemble, but an answer you get.
Where a pure analysis tool waits for you to feed it a parcel, our development site finder works the other direction. Pick a suburb and a product type — greenfield subdivision, townhouses, apartments, mixed-use, retail or bulky-goods, billboards, even energy and data-centre land — and GoSiteHunt scans the area and surfaces candidate sites. From there you can check subdivision potential, run a quick how-many-townhouses-fit yield estimate, and confirm controls with the zoning lookup. It also watches development applications near an address, and has an owner side: what is my site worth, and the option to sell off-market direct to developers with no agent and no commission.
New to the workflow? The guides walk it end to end — how to find development sites and how to calculate residual land value — and how it works shows the whole find-to-decision loop in one place. If you want to see a live market, browse development sites in Adelaide, South Australia as a worked example of the coverage. For a broader field view, see our full feasibility software comparison.
Global reach, instant answers, honest pricing
The three-word summary of the difference is global, instant, affordable. Deepblocks and most rivals are single-country, single-function, or enterprise-priced. GoSiteHunt is global and end-to-end, and it is deliberately cheap to try. You start free with 50 trial credits — a site report costs one credit and a whole-area scan costs five — so you can screen a real pipeline before spending a cent. Paid products are unbundled so you only buy what a live deal needs: a $49 vendor's report, Deal Flow alerts from $49/mo, a DocFlow planning report at $249 instant or $990 planner-reviewed, White-label at $99/mo, Assembly Pro at $299/mo, and Billboard or Energy Operator at $499/mo each. There is no five-figure platform fee standing between you and your first screen.
Read this before you rely on any number. GoSiteHunt outputs are indicative screening only — a fast filter to decide what deserves deeper work. They are not valuation, planning, financial or legal advice. Always confirm planning controls, market evidence and costs with the relevant authority and your own advisers before committing to a site.
Which should you choose?
Pick Deepblocks if you develop in its covered US cities and want massing plus a detailed pro-forma on parcels you already have. Pick TestFit or Archistar if your bottleneck is design and layout rather than deal selection. Pick GoSiteHunt if you need to find and screen opportunities fast, anywhere, and know the maximum you should pay before you make an offer — then hand the survivors to a deeper tool. Many developers run GoSiteHunt as the wide top-of-funnel filter and a specialist design tool for the handful of deals that clear it. The two are complements, not rivals.
Deepblocks alternatives: FAQ
- Is GoSiteHunt a direct Deepblocks replacement?
- Not exactly, and we would not claim it is. Deepblocks is strongest at 3D massing and detailed financial modelling on known US parcels. GoSiteHunt is strongest at finding candidate sites, screening feasibility and residual land value instantly, and doing it globally. If your job is scheme design on a parcel you already own, Deepblocks may fit better. If your job is deciding which sites to chase and what to pay, GoSiteHunt is the better front door.
- Does GoSiteHunt work outside the United States?
- Yes. GoSiteHunt returns address-level feasibility, yield, residual land value and a GO/NO-GO screen across 35+ countries. Deepblocks concentrates its deep zoning intelligence on covered US cities, so international coverage is one of the clearest reasons developers look for an alternative.
- Can GoSiteHunt find sites, or only analyse ones I already have?
- Both. The site finder scans a suburb by product type and surfaces candidate sites, and you can also drop in a specific address for an instant read. A whole-area scan costs five trial credits; a single site report costs one.
- How much does GoSiteHunt cost compared with Deepblocks?
- GoSiteHunt is free to start with 50 trial credits, with unbundled paid products such as a $49 vendor's report or Deal Flow alerts from $49/mo. Deepblocks publishes tiered monthly pricing that rises into enterprise levels as you add cities and deal flow. Confirm current figures on each vendor's own site before buying.
- What is residual land value and why does it matter here?
- Residual land value is the most you can pay for a site and still hit your target profit after build costs, fees and margin. It is the number that turns "you can build eight townhouses here" into "so do not offer more than X." GoSiteHunt surfaces it as a headline output; our RLV guide explains the method.
- Should I use GoSiteHunt and Deepblocks together?
- Many developers do. Use GoSiteHunt as the fast, global top-of-funnel filter to find and screen opportunities and set a maximum land price, then use a deeper design or massing tool on the handful of deals that pass. The two solve different stages of the acquisition workflow.
- Are GoSiteHunt's outputs reliable enough to make an offer on?
- They are reliable enough to decide what deserves your time, not to sign a contract on. Every output is indicative screening only — not valuation, planning, financial or legal advice. Use it to shortlist and to set a walk-away price, then verify controls, costs and market evidence with your advisers before committing.
