The short version

  • Each has a real cost: Felt felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process; IndoorAtlas requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • They diverge on capability: Felt covers Real-time collaboration, IndoorAtlas covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Felt

  • Felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process
  • Paid tiers are annual contract only with no monthly option, which excludes consultancies that need a tool for a single short engagement and forces them to the free non-commercial tier they are not licensed to use for client work
  • The API, JavaScript SDK and live warehouse connections are enterprise-only, so a mid-sized team that wants programmatic access has to buy the top tier rather than pay for one capability
  • Analytical depth is limited: there is no meaningful geoprocessing, topology checking or model building, so Felt sits beside a real GIS rather than replacing one
  • The Professional tier caps data processing at 25 GB a month and map views at 100,000 a month, which are easy to exceed with raster imagery or a public-facing map, and the overage terms are not published either

IndoorAtlas

  • Requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • Magnetic signatures degrade over time, requiring periodic re-fingerprinting as the environment changes
  • Magnetic interference from external sources and devices disrupts positioning accuracy
  • Positioning inconsistent across different smartphone models due to magnetometer heterogeneity
  • High cost to deploy and maintain, with expensive implementation for wide-scale adaptation

Answered from the vendors’ own pages

Felt: What does Felt cost?

Felt does not publish prices for Professional or Enterprise. Personal is free but licensed for non-commercial use only.

IndoorAtlas: How does IndoorAtlas determine positioning without beacons or hardware?

IndoorAtlas uses patented geomagnetic fusion technology that maps the Earth's magnetic field patterns inside buildings through a process called magnetic fingerprinting. The technology combines magnetometer data with other sensors like WiFi and Bluetooth for robust positioning.

Source
Felt: Can I pay monthly?

No. Paid plans are annual contracts. There is a 7 day trial of Professional.

IndoorAtlas: What is the initial setup process for IndoorAtlas?

Setup requires fingerprinting the venue by systematically walking through all corridors and spaces to build a magnetic map. The platform then identifies problematic areas through red (conflicting data), blue (insufficient coverage), and path orientation errors that require correction before the map is production-ready.

Source
Felt: Do viewers cost anything?

No. Viewer access is unlimited on the paid plans, which is the main reason organisations with large map audiences choose it.

IndoorAtlas: What are IndoorAtlas's pricing plans?

IndoorAtlas offers production subscriptions starting at 349 euros per month per venue, with a development plan at 400 euros per month. A free tier is available for developers to start building.

Source
Felt: Is there a nonprofit discount?

Yes, 30 per cent for verified United States nonprofits, and free access for verified students and classrooms.

IndoorAtlas: How accurate is IndoorAtlas positioning?

IndoorAtlas claims industry-leading accuracy down to 50 centimeters using its 6-layer sensor fusion core across diverse environments, though accuracy varies based on building magnetic patterns and requires careful calibration.
