The best Deepblocks alternatives depend on whether you are finding sites or deciding on one: for CRE deal work on a specific site, Titleman is our #1 pick, because it turns an address into a feasibility package (zoning, the schemes that fit, cost and return in a live Excel) with every figure traced to its source or formula. If you want self-serve zoning and 3D massing by city on a monthly plan, Deepblocks itself is a good fit, Zoneomics suits teams prospecting by zoning, and LandTech is the pick for UK sites.

Why teams look for Deepblocks alternatives
Deepblocks says it helps you find development sites and model their returns, with zoning intelligence for any U.S. city: "Know where you can build. And whether it pencils." Its DEV product, listed as available now, analyzes zoning and parcel potential with 3D massing, feasibility studies and financial models. AIM, AI agents that find and evaluate opportunities, is listed as coming October 2026. Market analysis, highest and best use reports, a precedent docket, zoning reports, zoning signals and a data API are listed as coming soon. It says zoning is built from ordinances with links to source pages, that missing values are estimated only when reliable measurements exist with the method recorded, and that requested cities go live within 0 to 3 business days.
Teams look at alternatives for reasons like these:
- A product they need is not live yet. Site selection, highest and best use and zoning reports are listed as coming.
- Per-city plans. Deepblocks sells DEV and AIM separately, each with an estimated number of active cities per plan. Teams working across many markets compare that with per-study tools.
- The hand-off. Lenders and investment committees often want a live workbook, a memo and the evidence behind each figure.
- Non-U.S. sites. Deepblocks describes U.S. cities.
When to stay with Deepblocks: if you want a self-serve monthly subscription with listed prices, 3D massing and financial models in the U.S. cities you work in, it does that directly, and on pricing clarity it scores higher than Titleman below.
How we ranked them
Five criteria, weighted for a CRE deal team:
- Address to answer (25%): zoning, schemes, cost and return from an address without setup.
- Traceability (25%): whether each figure can be traced to a source or a formula.
- Hand-off output (20%): a live Excel, memo or deck for a lender or IC.
- Site finding (15%): prospecting by zoning, parcel or ownership across an area.
- Pricing clarity (15%): whether the vendor states its pricing model on its own site.
Scores are 1 to 5 per criterion from each vendor's own website today, not hands-on tests of every product. Titleman was scored from its measured product facts; it gets 2 on site finding and 1 on pricing clarity.

The 5 best Deepblocks alternatives
1. Titleman
What it does. Titleman is an AI analyst for real estate. Send an address or APN and the feasibility study returns what the zoning allows (district, FAR, height, maximum buildable area) with each figure's source, runs every lawful use, class and unit size, keeps at most 10 schemes and ranks them by annual return on the asking price, saying why each losing scheme lost. Output is a 19-sheet live-formula workbook, a Word memo, a zoning PDF and an evidence ZIP. The measured median is 26.4 minutes from 13 September to 13 October 2026. For a building you own or are buying, the best use study compares keeping, converting, rebuilding and building up in one workbook. Titleman draws on 2,100+ sources and names what it could not find instead of filling it.
Best for. Acquisitions, development and lending teams who have a site and need a package to decide on. From the same address you can run comps (13.7 minutes from 13 September to 13 October 2026), a value opinion (35.1 minutes) and property underwriting (46.2 minutes). See highest and best use analysis.
Where it stops. It is not a map for scanning a whole city for sites, and it does not render 3D massing. The memo gives no final land price or go/no-go verdict; the numbers sit in the Excel.
2. Zoneomics
What it does. Zoneomics gathers zoning from fragmented city sources into zoning search, a prospecting tool that filters by zoning, permitted uses, lot width and height, a zoning API, and reports up to certified zoning letters. It cites more than 23,500 cities digitized and promotes Bassett.ai, an AI assistant for zoning.
Best for. Teams prospecting by zoning across many cities.
Where it stops. Zoning and prospecting; schemes and returns are outside it.
3. LandTech
What it does. LandTech is a UK land sourcing and site assessment tool: LandInsight for off-market and underused land with planning, ownership and policy data; LandFund for appraisals supporting funding applications; an AI assistant that writes site reports with click-through citations.
Best for. UK developers and land agents.
Where it stops. UK only.
4. TestFit
What it does. TestFit generates AI-based site plans editable down to the parking stall, with parking layouts, takeoffs, Site Intelligence and Pro Forma add-ons, and export to Revit, AutoCAD, SketchUp, Excel and PDF.
Best for. Design-led feasibility where the layout drives the numbers.
Where it stops. Finding sites is outside its stated job.
5. ARGUS EstateMaster
What it does. Altus Group describes ARGUS EstateMaster as software for developers to appraise development opportunities, with NPV, IRR and margin, debt, equity and JV modelling, and multi-stage and mixed-use scenarios.
Best for. Teams whose partners expect an EstateMaster appraisal.
Where it stops. It models the inputs you bring.

For self-serve zoning and 3D massing on a monthly subscription, Deepblocks itself remains a good fit. For UK sites, LandTech is built for that market.
Does Titleman do highest and best use like Deepblocks plans to?
Titleman has a live best use study for a building you own or are buying: it compares keeping, converting, rebuilding and building up, and shows in one workbook which option the zoning allows and how the returns compare. Deepblocks lists its highest and best use report as coming soon on its own site.
Which Deepblocks alternative is best for finding sites?
Zoneomics has a prospecting tool that filters properties by zoning, permitted uses, lot width and height, and LandTech surfaces off-market land in the UK. Titleman's strength is the study of a site once you have one.
How long does a Titleman feasibility study take?
The measured median is 26.4 minutes from 13 September to 13 October 2026 from an address or APN.
