Should you build or buy Indoor Positioning & Wayfinding?
Indoor positioning and wayfinding software turns a building's floor plans into a live map that helps visitors and staff navigate: blue-dot positioning, turn-by-turn directions, and points of interest inside malls, airports, hospitals, and large campuses. Buyers are venue operators who need visitors to find their way without asking staff.
Buy the positioning engine and SDK; own the floor-plan, POI and access data that feed it. Separate visitor wayfinding from asset tracking, which is a different system. Assemble it yourself only for a narrow case such as a maintained floor plan with QR 'you are here' or an iOS-only campus.
Build it, buy it, or bridge?
When building makes sense
Building your own indoor positioning system holds up only for a narrow case: a single venue with a floor plan that rarely changes, where a maintained map with a QR-code 'you are here' or a campus-only routing tool is enough. AI-powered mapping tools can now digitize a floor plan and generate the pathfinding network automatically, which removes a lot of the manual digitizing work that used to make this hard. Documented self-builds stay bounded to exactly that scope: a university's open-mapping campus routing project, a hospital's small local web wayfinding app, and Apple's Indoor Maps program, which only covers iOS. None of those reach the harder problems: dependable blue-dot positioning that works the same on iOS and Android, floor detection in a multi-level building, and keeping beacon infrastructure calibrated as the venue changes. If your venue needs that reliability at any real scale, building it yourself is a multi-year infrastructure project.
When buying makes sense
Buying is the right call for any venue where visitors actually need to find their way without asking staff. Mappedin runs maps at LAX, Miami International, Schiphol, and Simon malls, and offers both a self-serve AI mapping tool and a full-service team that builds the map for you. Pointr's positioning powers UCHealth's patient wayfinding across 60 floors and 12 buildings, with full integration into Epic MyChart, and the vendor reports deployments across more than 5,000 venues and 35 countries. Both vendors separate the map itself from the positioning layer, so you can buy the harder problem, cross-platform blue-dot accuracy and floor detection, while keeping your own floor-plan data and point-of-interest content. Buy the vendor's engine when your venue spans multiple floors, serves visitors on both iOS and Android, or needs accessibility features like turn-by-turn voice guidance. Build only for a single simple floor plan.

Frequently asked
What's the difference between an indoor map and indoor positioning?
A map is the static floor plan and point-of-interest data; positioning is the live blue dot that tracks where a visitor actually is inside the building. Open tools can produce a decent map. Reliable positioning across floors and device platforms is the harder engineering problem vendors are built to solve.
Can AI tools build my indoor map for me?
Largely, yes, for the map itself. Vendors including Mappedin now offer AI mapping that digitizes an uploaded floor plan and generates the walking-path network automatically, cutting most of the manual digitizing work. That doesn't extend to the positioning hardware and cross-platform accuracy layer underneath the map.
Does this apply to warehouses tracking assets, not just visitors?
No, treat that as a separate system. Visitor wayfinding is about helping a person find a destination on a map; asset tracking is about locating equipment or inventory in real time, and it needs different hardware and a different data model, even when the vendor sells both.
How much does an indoor positioning deployment cost?
Vendor self-serve mapping plans run roughly $250 to $485 a month. A large-site BLE self-deployment, buying and installing your own beacons, is estimated at $80,000 to $250,000 in the first year, which is why most venues buy the positioning layer rather than build it.
