The short version
- Only GRASS GIS has a free tier, so it costs nothing to try first.
- Each has a real cost: GRASS GIS the location and mapset data model requires importing data into a structured database with a fixed coordinate system before analysis, which is a real barrier for anyone used to opening files directly.; Leica Infinity leica publishes no pricing at all and sells through dealers, so identical firms in different regions pay different rates for the same modules and cannot benchmark a quote.
- They diverge on capability: GRASS GIS covers Raster analysis, Leica Infinity covers Multi-sensor project.

- An office preparing stakeout data and control for field crews on Leica Captivate and receiving as-built observations back into the same projectnot GRASS GIS
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GRASS GIS
- The location and mapset data model requires importing data into a structured database with a fixed coordinate system before analysis, which is a real barrier for anyone used to opening files directly.
- The native graphical interface is dated and inconsistent compared with QGIS or ArcGIS, so most users end up running GRASS through QGIS and never learn the tool they are actually depending on.
- There is no vendor, so contractual support, service levels and liability do not exist by default and must be arranged with an independent consultancy that may not cover your jurisdiction.
- Cartographic output and map layout are weak relative to the analysis capability, meaning a second tool is always needed to produce a publishable map.
- Module naming and argument conventions are idiosyncratic and long-standing, so scripts are durable but the learning curve is steep and transferable skills from other GIS packages help less than expected.
Leica Infinity
- Leica publishes no pricing at all and sells through dealers, so identical firms in different regions pay different rates for the same modules and cannot benchmark a quote.
- It is modular, which means the advertised capability list is not what you get: sensor and processing modules are licensed separately and the useful configuration costs considerably more than the entry one.
- Third-party instrument data is supported but always second-class; a mixed Leica and Trimble fleet will have one manufacturer’s raw data going through a lossier import path.
- Windows only, with no macOS, Linux or browser option, which is a hard constraint for organisations moving field and office work to tablets or cloud desktops.
- Perpetual licences require an ongoing customer care contract to receive updates and support, so the perpetual option saves less over five years than it first appears.

Questions people ask
- Is GRASS GIS or Leica Infinity better?
- Neither clearly leads. GRASS GIS starts at Free and Leica Infinity at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, GRASS GIS or Leica Infinity?
- GRASS GIS has a free tier; the other does not. Paid plans start at Free for GRASS GIS and On request for Leica Infinity.
- Does GRASS GIS or Leica Infinity run on more platforms?
- GRASS GIS runs on Linux, Windows, macOS. Leica Infinity runs on Windows.
- Can I use GRASS GIS for free?
- Yes. GRASS GIS has a free tier, so you can try it without paying. Leica Infinity starts at On request.
- What is GRASS GIS best used for?
- GRASS GIS is most often used for a hydrologist delineating watersheds and modelling flow accumulation over a large digital elevation model, a research group building a reproducible time series analysis of satellite imagery that must be rerunnable years later, an environmental agency running viewshed and solar radiation analysis for planning assessments without buying commercial gis seats, a qgis user who needs a specific processing algorithm that only exists in the grass toolbox. Of those, a hydrologist delineating watersheds and modelling flow accumulation over a large digital elevation model and a research group building a reproducible time series analysis of satellite imagery that must be rerunnable years later are not what Leica Infinity is typically brought in for.
- What can GRASS GIS do that Leica Infinity cannot?
- GRASS GIS covers Raster analysis, Hydrological modelling, Terrain analysis, Vector topology. Leica Infinity covers Multi-sensor project, Network adjustment, GNSS baseline processing, Point cloud handling.
Answered from the vendors’ own pages
GRASS GIS: Who maintains GRASS GIS?
An international volunteer and academic developer community under the Open Source Geospatial Foundation. It originated at the US Army Construction Engineering Research Laboratory in 1982.
Leica Infinity: Is Leica Infinity available as a perpetual licence?
Yes. Leica sells Infinity both as a subscription and as a perpetual licence, though updates on a perpetual licence require an active customer care contract.
GRASS GIS: Can I buy commercial support?
Not from a vendor. Independent consultancies in the OSGeo ecosystem offer paid support and development, and availability varies by region.
Leica Infinity: How much does it cost?
Leica does not publish prices. Infinity is quoted per module through authorised dealers.
GRASS GIS: Do I need to use its interface?
No. Most people run GRASS algorithms through the QGIS processing toolbox or from Python.
Leica Infinity: Does it work with non-Leica instruments?
It imports common third-party and standard formats, but Leica raw data is the first-class path. Expect reduced fidelity with competing raw formats.
GRASS GIS: Is it suitable for production use?
Yes for analysis pipelines, and it is used by agencies and research institutions. Plan for community support rather than a service level agreement.
Leica Infinity: Is there a free version?
No, only a 30-day trial.
Leica Infinity: Does it replace Cyclone for scanning?
No. Infinity handles scan data in a survey context; heavy registration and modelling work still belongs in Leica Cyclone.
