   GPT Best all-round self-hosted server: broad raster/vector datastore support, mature administration, styling, security, GeoWebCache, and unusually complete WMS, WFS/WFS-T, WCS, WMTS, and OGC API coverage.

   Claude Still the reference open-source OGC server — WMS, WFS, WMTS, WCS, and the newer OGC API endpoints, SLD/CSS styling, dozens of data-store connectors, security integration, and a web admin UI; when the requirement is standards-compliant interop with QGIS, ArcGIS, and enterprise portals, nothing self-hosted matches its breadth.

   Gemini The open-source enterprise standard for traditional GIS, providing unrivaled compliance with all OGC protocols (WMS/WFS/WCS) and a web GUI; ranked second because its heavy footprint is justified only when standard protocols and GUI administration are required.

   Where it falls short

   per GPT Its Java stack, extension management, and performance tuning create substantial operational overhead; it is excessive for tile-only applications.

   per Claude Java-heavy operational footprint — memory tuning, frequent CVE patching, and a dated admin UX; overkill and slower to serve tiles than purpose-built tile servers if all you need is a basemap.

   per Gemini Not for lightweight deployment environments or simple tile serving due to its high Java resource consumption and complex tuning.

   GPT #3Claude #1Gemini #1

   The fastest way to serve vector tiles straight from PostGIS — a single Rust binary with no JVM or Node runtime, auto-publishing tables and functions as MVT endpoints, plus MBTiles/PMTiles support and composite sources; now under the MapLibre umbrella with active development, it fits the modern MapLibre/vector-tile stack most practitioners are actually building on. Assumption: the typical user has data in PostGIS and wants dynamic vector tiles with minimal ops.

   Claude The fastest way to serve vector tiles straight from PostGIS — a single Rust binary with no JVM or Node runtime, auto-publishing tables and functions as MVT endpoints, plus MBTiles/PMTiles support and composite sources; now under the MapLibre umbrella with active development, it fits the modern MapLibre/vector-tile stack most practitioners are actually building on. Assumption: the typical user has data in PostGIS and wants dynamic vector tiles with minimal ops.

   Gemini Written in Rust, it is the fastest, most resource-efficient server for dynamic vector tile generation from PostGIS, MBTiles, and PMTiles, actively maintained under MapLibre; ranked first assuming the typical modern practitioner primarily builds vector-tile-first web applications.

   GPT The strongest lightweight choice for modern web maps, serving fast vector tiles directly from PostGIS, PMTiles, and MBTiles with minimal configuration and resource use.

   Where it falls short

   per GPT It is a focused tile server, not a full GIS service platform for WMS, WFS, editing, complex server-side cartography, or raster analysis.

   per Claude Vector tiles only — no WMS/WFS/OGC service compliance, no server-side raster rendering or print-quality styled output, so it can't replace a full OGC server in GIS-heavy or government-interop settings.

   per Gemini Not for teams needing a graphical administration GUI or legacy OGC raster services (WMS/WCS) out of the box.

   Offers unrivaled speed, security, and minimal memory usage for traditional OGC services using a mature C-based engine; nearly tied with QGIS Server but ranked higher due to superior performance under concurrent loads.

   Gemini Offers unrivaled speed, security, and minimal memory usage for traditional OGC services using a mature C-based engine; nearly tied with QGIS Server but ranked higher due to superior performance under concurrent loads.

   GPT Exceptionally fast, dependable, and resource-efficient for standards-based raster and vector publishing; its mapfile configuration is reproducible and well suited to long-lived production infrastructure.

   Claude Decades-proven C-based OGC server that remains the raw-performance leader for server-side rendered WMS from large raster and vector holdings; mapfile configuration is scriptable and rock-solid for high-throughput government/scientific deployments where uptime and speed beat convenience.

   Where it falls short

   per GPT Configuration is comparatively austere, with no first-class administration GUI and a steeper learning curve for teams expecting interactive styling and management.

   per Claude Mapfile syntax and CGI-era ergonomics feel archaic, there's no admin UI, and it has little to offer the vector-tile/MapLibre workflow that dominates new projects.

   per Gemini Not for developers who require a web GUI for configuration or REST APIs for runtime layer management.

   Where it falls short

   per GPT Scaling and automating a large multi-project service is less straightforward than its excellent desktop-to-web workflow.

   GPT #5Claude —Gemini #4

   The premier tool for serving vector and raster tiles from static MBTiles using MapLibre GL styles, providing server-side rendering for legacy client compatibility.

   Gemini The premier tool for serving vector and raster tiles from static MBTiles using MapLibre GL styles, providing server-side rendering for legacy client compatibility.

   GPT A practical self-contained route from MBTiles or PMTiles and MapLibre styles to vector tiles, rendered raster tiles, static maps, and an immediately usable viewer.

   Where it falls short

   per GPT It is best for prebuilt tile datasets; dynamic PostGIS querying and broad OGC service workflows belong elsewhere.

   per Gemini Not for lightweight container deployments due to severe image size and dependency overhead from headless OpenGL/X11 requirements.

   PProtomaps—3 pts

   GPT —Claude #3Gemini —

   Radically cheap self-hosting — the whole planet's basemap in one PMTiles file served via range requests from any static host, nginx, Caddy, or object storage, with no database or tile server process at all; for read-mostly basemaps it collapses infrastructure to near zero, and the open Protomaps basemap builds remove the OpenMapTiles licensing question. Near-tie with GeoServer — they solve opposite problems (zero-ops static basemaps vs. full dynamic OGC services).

   Where it falls short

   per Claude Static by design — no dynamic queries or live-updating data; refreshing content means regenerating the archive, so it's not for frequently changing operational layers.

   The strongest commercial turnkey option — polished installer, hosts vector/raster tiles, satellite imagery, and ready-made streets basemaps with built-in styling and a clean admin UI; ideal for teams (or air-gapped/on-prem deployments) that need Google-Maps-quality basemaps behind a firewall without assembling an open-source pipeline.

   Where it falls short

   per Claude Commercial licensing cost and data-package fees, and it's a closed appliance — less composable and extensible than the open-source stack it packages.
