Three open-source solutions serve this need: <strong>Tile38</strong>, <strong>PostGIS</strong>, and <strong>Redis Geo</strong>. Each brings a different philosophy to geospatial data management.</p> https://www.pistack.xyz/posts/2026-05-19-self-hosted-vector-tile-servers-tegola-vs-tileserver-gl-vs-martin-guide/ Tue, 19 May 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-05-19-self-hosted-vector-tile-servers-tegola-vs-tileserver-gl-vs-martin-guide/ <p>Vector tile servers transform raw geospatial data into Mapbox Vector Tiles (MVT), the standard format for interactive web maps. Instead of serving pre-rendered raster images, vector tile servers generate tiles dynamically from databases like PostGIS, enabling client-side styling, rotation, and 3D rendering. We compare the three leading open-source vector tile servers.</p>
