Martin is a tile server and a set of tools able to generate vector tiles on the fly from large PostgreSQL databases and GeoJSON files, and serve tiles from PMTiles and MBTiles files. It can also serve vector tiles from GeoParquet files via DuckDB (unstable). Martin optimizes for speed and heavy traffic, and is written in Rust.

Features

• Serve vector tiles from
  • PostGIS databases, automatically discovering compatible tables and functions
  • PMTile, both local files and over HTTP
  • MBTile files
  • GeoJSON files, converted to vector tiles on the fly
  • GeoParquet files via DuckDB, converted to vector tiles on the fly (unstable)
• Passthrough tiles from an upstream HTTP tile server
• Combine multiple tile sources into one
• Serve styles and generate sprites or font glyphs on the fly
• Generate tiles in bulk from any Martin-supported sources into an MBTiles file with martin-cp tool
• Examine, copy, validate, compare, and apply diffs between MBTiles files with mbtiles tool
