The short version

  • Only SAGA GIS has a free tier, so it costs nothing to try first.
  • Each has a real cost: PositionStack the free plan allows only 100 requests per month; 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: PositionStack covers Core Functionality, 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.

PositionStack

  • The free plan allows only 100 requests per month
  • The free plan is a personal licence, so commercial use requires a paid plan
  • The free plan is rate limited, with an extended rate limit only from the Basic plan up
  • Requests beyond the monthly quota are billed as overage, at $0.0003996 per request on Basic
  • The lowest advertised rates require annual prepayment
  • Enterprise volumes are priced by quote with no published 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
