How to choose digital twin software: a 2026 buyer’s checklist

This guide is for operations, facilities and IT leads comparing digital twin software, indoor mapping software and facility management software in 2026 for warehouses, factories, retail, malls, venues and logistics sites. The questions are vendor-neutral; where we describe Spatial Map, we include its limits so you can hold us to the same checklist.

“Digital twin” is stretched across very different products. Decide which category you are shopping in before comparing features: each is good at something, and trouble starts when a tool is asked to do a job it was not designed for.

Many organisations use more than one. A warehouse may keep its WMS as the system of record and run a live map beside it; we cover that split in digital twin vs WMS. This guide focuses on the operational twin: a facility map that stays current with live data and that people outside engineering can use.

A twin without a map is just a database. Nothing stalls an evaluation faster than weeks of manual drawing before anyone sees their own building. Ask:

• Floor-plan import: can it take the drawings you already have (a PDF drawing set, a DWG from CAD, or a PNG/JPG of the evacuation plan) and place them at true scale?
• Layers and units: for CAD, can you choose which layers to keep and read real-world units from the drawing?
• Time-to-first-map: how long from upload to a floor with racks, rooms or aisles placed? Time it yourself on one real floor.
• 3D and multi-floor: are stairs, lifts and escalators modelled, or is each level a flat image?
• Assisted drawing: does automatic detection give you drafts to review, or silently commit shapes you must later fix?
• Georeferencing: is the building placed on a real map, so sites and outdoor yards line up?

Spatial Map imports PDF drawing sets (the sheet is recognised from 17 standard ISO A, ANSI and ARCH sizes, so the plan lands at true scale), DWG files from R2004 to R2018 (you tick the layers to keep and confirm the drawing units) and PNG, JPG, GIF or WebP images. Every format becomes a floor-plan image placed at its real size on a georeferenced, multi-floor facility; walls, rooms and racks are then drawn on top with the editor tools. In the demo workspace, each of the 13 showcase facilities, from an airport terminal to a three-floor store, is traced over a real architectural floor plan, and Acme Warehouse carries 17 racks with 314 bins. See CAD and PDF import.

Live data is what separates a twin from a nice floor plan. Demos show data prepared for the demo; test how your own data gets in and what the map does with it.

• Ingest methods: which of your systems can be pulled on a schedule, which need to push into an API the vendor provides, and which only produce files (CSV, XLSX, JSON, GeoJSON)?
• Where the sync runs: on the vendor’s servers around the clock, or only while someone has the app open in a browser? This decides whether the night shift sees fresh data.
• Your own tables: if a system has no API, can you define a table and write to it through a generated REST API with scoped keys?
• Named connectors vs open interfaces: a wall of connector logos sounds reassuring, but ask what each one syncs. Open interfaces often matter more.
• Render modes: can one source become a live marker, value badge, coloured shape, heatmap, movement trail or camera field of view, without code?
• Health and auditing: when a feed fails at 3 a.m., is there a health view, an audit log and a list of failed runs?
• Latency: how many seconds from a change in your system to a change on the map?

Spatial Map has no named vendor connectors. Add integration offers three ways in: a REST API integration that pulls JSON, GeoJSON or CSV manually, whenever a map opens or on a timer (these syncs run in the browser of whoever has a map open, so the API must accept requests from the app); Upload file for CSV, XLSX, JSON or GeoJSON; and a Table with your own schema. A table can fill itself through server-side External REST polling, about once a minute at the fastest and even when nobody has a map open, or your systems push rows into it through its write API. There is no webhook or stream set-up in the app: an event-driven system such as a WMS or RFID middleware writes into a table, ideally in batches of up to 1,000 rows per call. See integrations, tables and the WMS integration guide.

A data link then binds a source to the map with one of nine render modes: live location marker, info marker on a shape, value badge on a shape, colouring a shape, heatmap of activity, movement trails, camera field of view, pulsing zone activity and historical movement. In the demo, Retail Mart Store uses them for RFID readers at its doors and escalators, shelf stock as percentage markers and fridge temperatures, and a write to a table reaches open maps within seconds. See data links.

A map that only its builder opens is a pilot that never scales. Check what happens once data is on the map.

• Reporting: can reports combine tables, charts and a live map and export to PDF, Excel and CSV, or does every report mean a separate BI tool?
• Starting points: does a new facility come with useful reports or a blank page?
• Wayfinding: can it route visitors or new staff between rooms, and across floors?
• Sharing: can you send a contractor or auditor a read-only view that expires and can be revoked?
• Roles: can people who only look at the map be prevented from editing it?
• Languages: is the interface available in your teams’ languages, including right-to-left scripts?

In Spatial Map every new facility starts with eight ready-made reports (Overview, Floors, Areas, Racks and more), and linking a table to a facility adds a report for that table. The step-by-step report builder adds KPIs, charts, editable tables and a facility map & list in Document, Grid or Full map layouts; Export produces PDF (through the browser’s print dialog), Excel, CSV or JSON, and each chart or KPI can also be saved as a PNG. The Retail Mart RFID Live Map report below is a full-map layout: the list of RFID readers on the left, the store on a live map and an Insights panel with reader status and reads by floor. See reports.

Share links open a read-only viewer and can expire (from one hour to one year, on a custom date, or never), stop after a maximum number of views, and be revoked. Members get one of four roles (Owner, Admin, Editor or Viewer), and an invitation goes to someone who already has a Spatial Map account. In the viewer, Navigate draws a route between two points on a floor with turn-by-turn directions, and the interface ships in six languages, including right-to-left Arabic. See share links, members and roles and wayfinding.

Share facility: expiry and view cap

• Multi-site organisation: with several warehouses or a university campus, can you group facilities, reports and data by use case?
• Browser vs installed: does it run in a normal browser, or need a desktop install, plug-ins or a powerful GPU?
• Pricing transparency: is there a published price and a clear billable unit? What happens when you add the next site?
• Data ownership: can you export records and reports yourself, and does your source system stay the system of record?
• Security: ask about tenant isolation, session handling, rate limiting and API key storage, and ask for evidence behind any certification on the sales slide.

In Spatial Map, solutions group the facilities, reports, tables and integrations of one use case. You start from an industry template (warehouse, retail, anti-theft, manufacturing or logistics, among others) or a blank one; an item can sit in several solutions, and deleting a solution never deletes its contents. The app runs in a modern browser with no install. Pricing is published: a 7-day trial with up to 5 facilities and no card, then Pro at $60/month or $600/year for up to 4 facilities per workspace; larger estates can contact us. On the server every query is scoped to the workspace, and table API keys are stored hashed.

Solution templates for grouping a site

Copy this table into your evaluation sheet. Score each vendor 0 (no or unclear), 1 (partly, or only through paid services) or 2 (yes, shown live on your own data). A demo on the vendor’s sample data scores at most 1.

Here is how we answer our own checklist, limits included. A buyer’s guide that hides limits is a brochure.

A checklist narrows the field; a pilot decides. Two weeks is enough with one facility and one or two decisions. With Spatial Map, the 7-day free trial covers the build week; if it shows value, move to Pro for week two with real users.

1. 1
   Day 1: pick the facility and the decision

   Choose one site and the one or two decisions the twin must support. Gather its floor plans and a sample of the data behind those decisions.

2. 2
   Days 1–2: build the map

   Import the floor plan (PDF, DWG or image), set up floors and draw the racks, zones or rooms that matter. Time it: this is your real time-to-first-map.

3. 3
   Days 3–4: connect one live source

   Connect one feed (a REST API integration, a file upload, or a table that your system writes to or that polls your endpoint) and bind it to the map with a data link. Watch the Health tab for a full day; for a feed that must run unattended, use a table rather than a browser-run REST sync.

4. 4
   Day 5: build one report

   Start from the built-in facility reports, then build the one report your decision-maker will actually open. Export it to PDF or Excel.

5. 5
   Days 6–7: share and score

   Invite one colleague as a Viewer (they need a Spatial Map account first), send one read-only share link outside the team, and score the tool against the checklist with its future users.

6. 6
   Week 2: run it for real

   If week one passed, run the twin in daily operations and note what people actually used. If not, you have lost a week, not signed a contract.
