The short version

  • Each has a real cost: AllTrails the App Store listing shows AllTrails is a free download with an in-app Pro subscription; the visible listing text does not state the Pro price, so the reader must check in-app purchases for the current rate.; 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: AllTrails covers Trail discovery, SAGA GIS covers Terrain morphometry.
  • 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.

AllTrails

  • The App Store listing shows AllTrails is a free download with an in-app Pro subscription; the visible listing text does not state the Pro price, so the reader must check in-app purchases for the current rate.

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

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.

AllTrails: Can I create custom routes on AllTrails?

Yes, AllTrails allows users to build and edit custom trails. The platform provides route converter tools and options to print custom maps for your own trail designs.

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.

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.

SAGA GIS: What licence is it under?
