The short version
- Each has a real cost: Fused the price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.; IndoorAtlas requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
- They diverge on capability: Fused covers User defined functions, IndoorAtlas covers Core Functionality.

What people use each for
The jobs each tool is most often brought in to do.
Fused
- A data team that wants to publish a dynamic layer computed from a large Parquet dataset without standing up and operating a tile servernot IndoorAtlas
- An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot IndoorAtlas
- An application that needs a geospatial computation exposed as an HTTP endpoint, where the alternative is a container, a queue and an on-call rotanot IndoorAtlas
- A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot IndoorAtlas
IndoorAtlas
- Routing customers to deals in large retail spacesnot Fused
- Guiding visitors through shopping centers and airportsnot Fused

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Fused
- The price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.
- Published tiers do not state the actual compute, storage or request allowances, so the only way to know whether $200 covers your workload is to run it and find out.
- Fused is at pre-seed stage with a small team, and putting a customer-facing map behind a startup’s serverless platform is a continuity risk that a procurement review will flag.
- It is Python-only and assumes competence with cloud-native geospatial formats; there is no path for an analyst who works in a desktop GIS and not in code.
- Serverless execution means cold starts and per-tile latency on uncached views, so a first load of a heavy UDF over a wide area is noticeably slower than a pre-rendered tile set.
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

Questions people ask
- Is Fused or IndoorAtlas better?
- Neither clearly leads. Fused starts at Free and IndoorAtlas at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Fused or IndoorAtlas?
- Fused starts at Free and IndoorAtlas at Free.
- Does Fused or IndoorAtlas run on more platforms?
- Fused runs on Web, Linux, macOS, Windows. IndoorAtlas runs on iOS, Android, Web.
- Can I use Fused for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Fused best used for?
- Fused is most often used for a data team that wants to publish a dynamic layer computed from a large parquet dataset without standing up and operating a tile server, an analyst prototyping against overture, sentinel or census data who needs a working map in an afternoon rather than a data engineering ticket, an application that needs a geospatial computation exposed as an http endpoint, where the alternative is a container, a queue and an on-call rota, a consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tiles. Of those, a data team that wants to publish a dynamic layer computed from a large parquet dataset without standing up and operating a tile server and an analyst prototyping against overture, sentinel or census data who needs a working map in an afternoon rather than a data engineering ticket are not what IndoorAtlas is typically brought in for.
- What can Fused do that IndoorAtlas cannot?
- Fused covers User defined functions, Instant tile endpoints, HTTP API, Caching. IndoorAtlas covers Core Functionality, User Interface.
Answered from the vendors’ own pages
Fused: What does Fused actually give me?
A Python function becomes a map tile endpoint and an HTTP API on managed infrastructure, with caching, without you running a server.
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.
SourceFused: How much does it cost?
Free, then $20, $200 and $2,000 per month for Starter, Developer and Professional. Usage allowances are not itemised publicly.
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.
SourceFused: Can I run UDFs locally?
Yes, through the Python SDK, which is how most development is done before deploying.
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.
SourceFused: Does it replace PostGIS or BigQuery?
No. It reads from them. Fused is the compute and serving layer, not the store.
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.
SourceFused: Is it a mature company?
No. It is a small pre-seed San Francisco company. The technology is real; the vendor risk is real too.
