The short version

  • Each has a real cost: OpenStreetMap data accuracy varies dramatically by geographic region depending on volunteer coverage; SW Maps android only. There is no iOS version and no sign of one, which rules it out for organisations that issue iPhones and iPads to field staff.
  • They diverge on capability: OpenStreetMap covers Core Functionality, SW Maps covers Custom feature layers.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

OpenStreetMap

  • Community mapping of roads, trails, cafes and railway stationsnot SW Maps
  • Projects that need open map data and can meet the attribution requirementnot SW Maps
  • Building on map data where a share-alike licence is acceptablenot SW Maps

SW Maps

  • An NGO or municipal utility mapping water points, pipe networks or road assets on a budget that cannot absorb per-user GIS subscriptionsnot OpenStreetMap
  • A survey team pairing a low-cost RTK receiver with Android tablets to collect centimetre-accurate attributed features without buying field software seatsnot OpenStreetMap
  • A university field course teaching GNSS data collection where every student needs the tool on their own devicenot OpenStreetMap
  • A consultant doing a one-off asset inventory who needs shapefile or GeoPackage output and does not want to start an annual subscription for a three-week jobnot OpenStreetMap

Where each one falls short

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

OpenStreetMap

  • Data accuracy varies dramatically by geographic region depending on volunteer coverage
  • No minimum quality standards enforced, making data prone to errors and inconsistencies
  • Data completeness gaps, especially for minor roads and remote areas
  • Bias toward well-mapped regions with high volunteer activity
  • Positional accuracy concerns with only 70-76% of roads within 5-10 meter tolerance
  • Tag criteria not well-defined leading to logical consistency issues

SW Maps

  • Android only. There is no iOS version and no sign of one, which rules it out for organisations that issue iPhones and iPads to field staff.
  • There is no back end: no user management, no central project sync, no audit trail. Data lives on the device until someone exports it, and a lost tablet is lost data.
  • No commercial support contract exists, so an organisation with a compliance requirement for vendor support cannot use it for regulated work regardless of technical fit.
  • It is maintained by a small consultancy as a side product of its own project work, so the roadmap follows Softwel’s needs and a feature you depend on may never be prioritised.
  • Form logic is basic compared with dedicated survey platforms: no meaningful skip logic, validation or multi-user assignment, so complex questionnaires quickly outgrow it.

Questions people ask

Is OpenStreetMap or SW Maps better?
Neither clearly leads. OpenStreetMap starts at Free and SW Maps at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, OpenStreetMap or SW Maps?
OpenStreetMap starts at Free and SW Maps at Free.
Does OpenStreetMap or SW Maps run on more platforms?
OpenStreetMap runs on Web, API. SW Maps runs on Android.
Can I use OpenStreetMap for free?
Both have a free tier, so you can try either at no cost before committing.
What is OpenStreetMap best used for?
OpenStreetMap is most often used for supplying map data to websites, mobile apps and hardware devices, community mapping of roads, trails, cafes and railway stations, projects that need open map data and can meet the attribution requirement, building on map data where a share-alike licence is acceptable. Of those, supplying map data to websites, mobile apps and hardware devices and community mapping of roads, trails, cafes and railway stations are not what SW Maps is typically brought in for.
What can OpenStreetMap do that SW Maps cannot?
OpenStreetMap covers Core Functionality, User Interface. SW Maps covers Custom feature layers, External GNSS support, Offline basemaps, Geospatial PDF layers.

Answered from the vendors’ own pages

OpenStreetMap: Is OpenStreetMap free to use?

Yes, OpenStreetMap is completely free and open-source under the Open Data Commons license. You can download and use map data for any purpose.

Source
SW Maps: Is SW Maps really free?

Yes. It is free with no advertising and no paid tier. There is no subscription and no feature paywall.

OpenStreetMap: How accurate is OpenStreetMap?

OpenStreetMap accuracy varies by region. In well-mapped areas like developed countries, accuracy is generally high. Only 76% of OSM roads aligned within 10 meters of reference roads, with 70% within 5 meters.

Source
SW Maps: Does it support RTK receivers?

Yes, over Bluetooth or USB serial, with NTRIP correction support, antenna height and per-point fix quality recording.

SW Maps: Is there an iOS version?

No. Android only.

SW Maps: Who maintains it?

Softwel, an engineering consultancy in Kathmandu, Nepal, which built it for its own infrastructure projects.

SW Maps: Can we get support?

Not contractually. There is no commercial support agreement, which is the main reason organisations with compliance obligations choose a paid alternative.
