The short version

  • Only SAGA GIS has a free tier, so it costs nothing to try first.
  • Each has a real cost: ArcGIS Field Maps field Maps has no price of its own, so a project budget built from the product page misses the Creator seats, the Mobile Worker seats and the ArcGIS Online credits or Enterprise infrastructure that actually cost money; SAGA GIS there is no commercial support contract available from anyone, so a procurement process that requires a named supplier with a service level cannot be satisfied and the organisation carries the whole operational risk itself
  • They diverge on capability: ArcGIS Field Maps covers Offline map areas, SAGA GIS covers Terrain morphometry.
  • Prices and features above were last checked on 1 September 2026.

What each one covers

Drawn from each product's published feature list. An absence here means we hold no record of it - not that the product lacks it.

What people use each for

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

ArcGIS Field Maps

  • A water utility whose inspectors update the same asset feature service the office GIS runs on, rather than filling in forms that someone re-keysnot SAGA GIS
  • A county carrying out a sign inventory where crews work in areas without mobile coverage and need offline maps that sync laternot SAGA GIS
  • An environmental team needing sub-metre positions from an external GNSS receiver recorded directly against the authoritative datasetnot SAGA GIS
  • An organisation consolidating from Collector, Explorer, Tracker and Workforce onto a single app after Esri retired themnot SAGA GIS

SAGA GIS

  • A hydrologist deriving catchment boundaries and flow networks from a national elevation model at a resolution commercial tools slow down onnot ArcGIS Field Maps
  • A soil science team producing interpolated property surfaces with documented geostatistical methods for a peer-reviewed papernot ArcGIS Field Maps
  • A government environmental analyst who needs a terrain index that no commercial GIS implements and does not want to write it from scratchnot ArcGIS Field Maps
  • A QGIS user who has hit the limits of the native toolbox and needs the SAGA algorithms already exposed in the processing frameworknot ArcGIS Field Maps

Where each one falls short

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

ArcGIS Field Maps

  • Field Maps has no price of its own, so a project budget built from the product page misses the Creator seats, the Mobile Worker seats and the ArcGIS Online credits or Enterprise infrastructure that actually cost money
  • It only works against Esri feature services, so an organisation whose data is in PostGIS or a database without an ArcGIS layer must publish through Esri first, which is a platform decision rather than an app choice
  • Named user licensing means occasional or seasonal field staff still consume a full annual seat, and organisations with a large pool of infrequent collectors pay for capacity they use a few weeks a year
  • As a forms tool alone it is more rigid and more expensive than dedicated mobile forms products, so its value collapses if you are not already committed to ArcGIS
  • The consolidation of four apps into one changed established workflows, and organisations that had built processes around Collector or Workforce have had to rework them on Esri's timetable rather than their own

SAGA GIS

  • There is no commercial support contract available from anyone, so a procurement process that requires a named supplier with a service level cannot be satisfied and the organisation carries the whole operational risk itself
  • The project explicitly states that everyone working on it has another job and that answers may take a while, which means an urgent production failure has no escalation path
  • The interface is dated and inconsistent across modules, and cartographic output is poor, so most users treat it as an analysis engine and produce maps somewhere else
  • Documentation for many of the several hundred modules is a parameter list without explanation of method or expected input, so choosing the right algorithm often requires reading the source or a published paper
  • Development is concentrated in a small group, which creates real key-person risk: a change in the circumstances of a handful of maintainers would slow or stop releases, and there is no organisation obliged to continue them

Questions people ask

Is ArcGIS Field Maps or SAGA GIS better?
Neither clearly leads. ArcGIS Field Maps starts at On request and SAGA GIS at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, ArcGIS Field Maps or SAGA GIS?
SAGA GIS has a free tier; the other does not. Paid plans start at On request for ArcGIS Field Maps and Free for SAGA GIS.
Does ArcGIS Field Maps or SAGA GIS run on more platforms?
ArcGIS Field Maps runs on iOS, Android, Web. SAGA GIS runs on Windows, Linux, macOS.
Can I use SAGA GIS for free?
Yes. SAGA GIS has a free tier, so you can try it without paying. ArcGIS Field Maps starts at On request.
What is ArcGIS Field Maps best used for?
ArcGIS Field Maps is most often used for a water utility whose inspectors update the same asset feature service the office gis runs on, rather than filling in forms that someone re-keys, a county carrying out a sign inventory where crews work in areas without mobile coverage and need offline maps that sync later, an environmental team needing sub-metre positions from an external gnss receiver recorded directly against the authoritative dataset, an organisation consolidating from collector, explorer, tracker and workforce onto a single app after esri retired them. Of those, a water utility whose inspectors update the same asset feature service the office gis runs on, rather than filling in forms that someone re-keys and a county carrying out a sign inventory where crews work in areas without mobile coverage and need offline maps that sync later are not what SAGA GIS is typically brought in for.
What can ArcGIS Field Maps do that SAGA GIS cannot?
ArcGIS Field Maps covers Offline map areas, Smart forms, High-accuracy GNSS, Location sharing. SAGA GIS covers Terrain morphometry, Hydrological modelling, Geostatistics, Image analysis.

Answered from the vendors’ own pages

ArcGIS Field Maps: Can I buy Field Maps on its own?

No. It is included with the Mobile Worker, Creator and GIS Professional user types, and you need at least one Creator in the organisation to author maps.

SAGA GIS: Who maintains SAGA GIS?

A small international developer community, originating from physical geography departments at the universities of Göttingen and Hamburg. It is hosted on SourceForge and releases continue in the 9.x line.

ArcGIS Field Maps: What replaced Collector and Workforce?

Field Maps. Esri merged Collector, Explorer, Tracker and Workforce into it and retired the separate apps.

SAGA GIS: Can I buy support?

No. There is no vendor and no commercial support contract. The project itself states there is no hotline and no guaranteed support.

ArcGIS Field Maps: Does it work offline?

Yes. Map areas are downloaded in advance and edits synchronise when connectivity returns.

SAGA GIS: Do I need SAGA if I already run QGIS?

Often not, because many SAGA algorithms are available through the QGIS processing toolbox. Install SAGA directly when you need modules QGIS does not expose or want to script them independently.

ArcGIS Field Maps: Can it write to a non-Esri database?

Not directly. The data must be published as an ArcGIS feature service, which may sit over an enterprise geodatabase you already run.

SAGA GIS: What licence is it under?

The GNU General Public Licence, so you can modify and redistribute it under the same terms.
