Visibility in this ranking can be paid for. Payment gives a vendor more visibility, higher up on the review pages; it never adds a vendor, and it never changes a word of the review. The largest vendors in GIS software
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,
wherever the category has them; the established names follow from place 4 in their ranked order. How it works: placement disclosure ·

The 12 tools, reviewed
#1 Felt
Browser-based GIS for sharing and analyzing maps · United States · felt.com
Web GIS Published prices Field capture
Felt is the product to try first when the people who need maps are planners, analysts and managers rather than GIS specialists. The pricing page lists every tier with a number, says viewers are free on every plan and that nothing is added to the bill automatically, which is unusual in this category. A free plan covers sketching and public sharing.
- Pricing: Per seat / month. Free plan with 3 seats and 25 viewers. Free plan: free plan.
- Best for: Teams sharing maps without GIS staff
- Strengths: Map annotation and real-time collaboration; Upload and styling of vector and raster data; Cloud database and bucket connections.
Where it falls short
Free-plan users cannot upload data or export, so the free tier is a sketch pad rather than a trial of the real product. Processing and map views are capped per month and rise with the tier.
Wrong for
Wrong for a GIS office that edits geodatabases daily or needs print-quality cartography.

#2 QGIS
Free open-source desktop GIS for Windows, Mac and Linux · Switzerland · qgis.org
Open source Desktop GIS Plugin ecosystem
QGIS gives a small organization the editing, analysis and cartography that other vendors sell per seat, and the project states that it is owned by its contributors and licensed under GNU GPLv2+. It runs on Windows, Mac and Linux, so it fits mixed offices, and its plugin library covers specialty work.
- Pricing: Open source + paid tiers. Free and open source under GNU GPLv2+; support is bought separately from service providers and local user groups. Free plan: open source.
- Best for: Technical teams that want no license fees
- Strengths: Cartographic design and print layouts; Plugin library; Windows, Mac and Linux builds.
Where it falls short
No vendor answers the phone. Upgrades, plugin compatibility and training are the owner's job, and a plugin written by one volunteer can break after a release.
Wrong for
Wrong for a manager who wants a map shared by Friday with nobody on staff to learn it.

#3 Mergin Maps
Field data collection that syncs with QGIS projects · United Kingdom · merginmaps.com
Field survey QGIS plugin Per contributor
Mergin Maps is the quickest route from a QGIS project to a phone in a surveyor's hand. Forms are designed in QGIS, collected offline on mobile devices and synced to a shared project, and the page notes project history so edits can be reviewed.
- Pricing: Per user / month. Premium is €15.8 per contributor a month billed annually (€19.5 monthly) with 1 GB per contributor; Enterprise is modular on request. Free plan: free trial.
- Best for: Survey teams already using QGIS
- Strengths: Mobile data collection; QGIS plugin for project setup; Customizable forms.
Where it falls short
It is a collection and sync tool, not a general GIS, so analysis and cartography still happen in QGIS.
Wrong for
Wrong for an office that does only desktop analysis and no field work, or for a team that wants a hosted map editor with no QGIS.

#4 CARTO
Spatial analytics on cloud data warehouses · United States · carto.com
Warehouse-native Spatial analytics Enterprise
CARTO treats the warehouse as the GIS: data stays in Google Cloud, AWS, Azure, Snowflake, Databricks or Oracle, and CARTO adds maps, spatial functions and app building on top. That fits a data team that already keeps customer or asset tables in a warehouse and wants them on a map without exporting.
- Pricing: Usage-based. Pay As You Go metered by consumption on a 12-month contract; Enterprise, Strategic and Custom tiers by quote; free 30-day trial. Free plan: free trial.
- Best for: Analysts working in a data warehouse
- Strengths: Visualization and dashboards; Spatial analytics inside the warehouse; Data enrichment.
Where it falls short
The pricing page shows no dollar figures, only plan shapes and a quote button, and Pay As You Go comes with a 12-month contract. The trial is for evaluation and production use is not permitted.
Wrong for
Wrong for a team whose data lives in spreadsheets and shapefiles.

#5 Global Mapper
Desktop GIS focused on lidar, terrain and geodetics · United States · bluemarblegeo.com
Lidar Surveying Desktop
Global Mapper is aimed at people who start from raw measurements: point clouds, imagery, elevation grids and survey data. Blue Marble describes combining lidar and point cloud processing, photogrammetric outputs and geodetic checks in a single desktop application, and it sells the MAPublisher extension for cartographers working in Adobe Illustrator.
- Pricing: Quote only. Purchase and free trial are offered through the vendor's site; the pricing page we fetched returned an error, so prices are on request. Free plan: free trial.
- Best for: Surveyors and lidar processors
- Strengths: Lidar and point cloud processing; Terrain and imagery handling; Geodetics and coordinate systems.
Where it falls short
No price is stated in text we could read, so budgeting needs a sales contact. Its strengths are measurement and terrain; teams wanting a shared web map, dashboards or a data warehouse link will need other products.
Wrong for
Wrong for a retail or marketing team that wants shared location dashboards.

#6 Esri ArcGIS Pro
Esri's desktop GIS, sold through ArcGIS user types · United States · esri.com
Incumbent Desktop GIS Enterprise platform
ArcGIS Pro is the default in government, utilities and consulting, and that is a practical reason to own it: partners send files in Esri formats and expect results in them.
- Pricing: Per user / month. Included in ArcGIS Online or ArcGIS Enterprise user types at Basic, Standard and Advanced levels; annual licenses, with no prices on Esri's page. Free plan: free trial.
- Best for: Organizations exchanging data with Esri users
- Strengths: Basic, Standard and Advanced license levels; Advanced editing and data validation; Spatial modeling and big-data analysis.
Where it falls short
No price appears on the pages we read; buying means choosing among user types and extensions with a sales contact.
Wrong for
Wrong for a five-person company that makes a few maps a month.

#7 MapInfo Pro
Desktop location-intelligence GIS from Precisely · United States · precisely.com
Legacy desktop Raster handling Precisely data
MapInfo Pro has an installed base that predates most products in this list, and Precisely keeps it current with Python support alongside the older MapBasic language. Its Multi-Resolution Raster format is pitched at very large raster datasets, and geocoding and drive-time analysis connect to Precisely's own data.
- Pricing: Per user / month. 1 to 3 year subscriptions at a reduced price compared with older licensing; a 30-day free trial; no figure on the page. Free plan: free trial.
- Best for: Long-time MapInfo users and data-heavy teams
- Strengths: Multi-Resolution Raster format; Multi-Resolution Virtual Raster; MapBasic and Python scripting.
Where it falls short
Sold as a subscription now, with the vendor stating a reduced price but publishing no figure. Imagery services such as Bing depend on subscription continuity.
Wrong for
Wrong for a new team starting without legacy tables or scripts.

#8 Manifold
Low-cost Windows GIS and spatial database tool · Hong Kong · manifold.net
One-time price GPU parallel Windows
Manifold is the odd product of this ranking: a one-time $145 license for a desktop that the vendor says uses all CPU cores and multiple GPUs, with free updates and a free Viewer for sharing projects.
- Pricing: One-time license. Release 9 is listed at $145 as a fully paid license with free updates; a free Viewer and trial editions are offered. Free plan: free trial.
- Best for: Analysts with big datasets on a budget
- Strengths: CPU and GPU parallel processing; Spatial SQL; Read and write Esri geodatabases.
Where it falls short
The vendor names only Windows 10 and 11 as supported platforms. The interface and documentation are unlike the mainstream tools, so staff hired from other GIS shops need retraining.
Wrong for
Wrong for Mac-based teams or organizations whose procurement requires a large vendor with a service-level agreement.

#9 Cadcorp SIS
Desktop, web and server GIS from NEC Geospatial Solutions · United Kingdom · necsws.com
UK public sector Desktop and web OS data
Cadcorp's Spatial Information System is a family covering desktop, server, web and developer products, which lets a council or insurer run editing, publishing and applications from one vendor. NEC says it can license spatial data, including all Ordnance Survey products, alongside the software, which simplifies purchasing for UK organizations. Finance and insurance buyers also get applications for accumulation analysis and perils management.
- Pricing: Quote only. No price or trial terms on the pages read; the vendor directs buyers to book a demo or ask an expert. Free plan: none.
- Best for: UK public-sector spatial data teams
- Strengths: SIS Desktop; SIS WebMap; SIS Address Loader and ETL.
Where it falls short
The page shows no prices, no trial and no self-service signup.
Wrong for
Wrong for a small non-UK company wanting to test before paying.

#10 FME
No-code data integration for spatial data · Canada · fme.safe.com
Data integration Format conversion Automation
FME does not draw maps. It moves and reshapes spatial and non-spatial data between formats and systems with a no-code workflow editor, and a GIS team that merges parcel feeds, converts CAD to geodatabase or schedules nightly updates gets back days of manual work.
- Pricing: Quote only. Described as a subscription crafted to each customer; no figures or trial terms on the pricing page we could read. Free plan: none.
- Best for: GIS teams converting data between systems
- Strengths: No-code workflow builder; Spatial data transformation; FME Flow hosted option.
Where it falls short
The pricing page shows no numbers and describes bespoke subscriptions, and we found no trial terms in the text we could read.
Wrong for
Wrong for a buyer who needs a first map and has no data pipeline problem.

#11 GRASS GIS
Free open-source engine for geospatial analysis · United States · grass.osgeo.org
Open source Analysis engine Research
GRASS GIS is built for analysis rather than presentation: the project describes it as optimized for large-scale processing across hardware configurations, and it ships for Windows, macOS and Linux with Docker and conda options. Researchers, hydrologists and environmental consultants use it for terrain, raster and time-series work, and many run it from QGIS.
- Pricing: Open source + paid tiers. Free and open source; community and commercial support are listed on the project site. Free plan: open source.
- Best for: Researchers running heavy raster analysis
- Strengths: Large-scale spatial analysis; Command-line and scripting use; Windows, macOS and Linux builds.
Where it falls short
It has the steepest learning curve of any product listed, and the command structure assumes you think in terms of locations and mapsets. Map layout and styling are modest compared with QGIS.
Wrong for
Wrong for office staff who want to drag a spreadsheet onto a map.

#12 GeoServer
Open-source server that publishes maps and data as OGC services · United States · geoserver.org
Open source Map server OGC standards
GeoServer is the open standard answer to a question every growing GIS meets: how do other systems read our layers. It is certified for Web Feature, Web Map, Web Coverage and Web Map Tile Services, and adds OGC API Features and Web Processing Service as extensions, so QGIS, web apps and third-party tools can all consume one source.
- Pricing: Open source + paid tiers. Free and open source; the project lists a stable 3.0 line, a 2.28 maintenance line and nightly builds. Free plan: open source.
- Best for: Developers publishing layers over standards
- Strengths: WMS and WFS; WCS and WMTS; OGC API Features extension.
Where it falls short
It publishes data but does not create it: there is no map-making desktop, and end users cannot edit styles without an administrator.
Wrong for
Wrong for a team looking for a map editor or a dashboard.

Questions and answers
What is the best GIS software in 2026?
Felt ranks first of 12, best for teams sharing maps without GIS staff. QGIS is second (technical teams that want no license fees) and Mergin Maps third (survey teams already using QGIS). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is QGIS really free, and what does that leave out?
QGIS is licensed under GNU GPLv2+ and the project says it stays free and open source.
Do I need desktop GIS, or is a browser tool enough?
A browser tool is enough when the work is viewing, styling, filtering and sharing layers, which covers site selection, territory maps and client reports.
What does GIS software cost for a five-person team?
It ranges from nothing to several thousand dollars a month. QGIS, GRASS GIS and GeoServer have no license fee. Manifold lists a $145 desktop license.
Which spatial file formats should I be able to export?
At a minimum GeoPackage, Shapefile, GeoJSON and KML for vector data and GeoTIFF for rasters. Felt lists GeoPackage, Shapefile, KML, GeoJSON and GeoTIFF exports on its paid plans, and notes that CSV and GeoParquet exports exist for analytics.
Can GIS software publish maps to other applications?
Yes, through standard web services. GeoServer is OGC certified for WMS, WFS, WCS and WMTS and lists OGC API Features and Web Processing Service as extensions, so QGIS, web apps and other software can read its layers.
What is the difference between GIS software and a maps API?
A maps API supplies map tiles, geocoding and routing to an app you build, billed per request. GIS software lets a person load, edit, analyze and style spatial datasets and publish the result.
Is Esri ArcGIS Pro worth the price for a small company?
Only when its ecosystem is the point. ArcGIS Pro is sold through ArcGIS user types, with Basic, Standard and Advanced license levels, and Esri's own page quotes no prices, so a small company needs a sales conversation.
How do I move from MapInfo or another legacy desktop?
Start with an inventory of table and workspace files, then test an export to GeoPackage or Shapefile and open the result in QGIS to see how attributes and styles come through.
Which GIS software works for collecting data in the field?
Mergin Maps is built around it: forms are designed in QGIS, collected on phones and tablets, and synced to a shared project, with Premium listed at €15.8 per contributor a month.
What happens to my data if the GIS vendor is acquired or retires a product?
Files in open formats stay usable, but hosted layers, web maps and apps depend on the vendor keeping the service running.
