Martin is a tile server and a set of tools able to generate vector tiles on the fly
from large PostgreSQL databases, and serve tiles from PMTiles and MBTiles files. Martin optimizes for speed and heavy traffic, and is written in [Rust](https://github.com/rust-lang/rust).

## Features

* Serve [vector tiles](https://github.com/mapbox/vector-tile-spec) from
  * [PostGIS](https://github.com/postgis/postgis) databases, automatically discovering compatible tables and functions
  * [PMTile](https://protomaps.com/blog/pmtiles-v3-whats-new), both local files and over HTTP
  * [MBTile](https://github.com/mapbox/mbtiles-spec) files
* [Combine](https://maplibre.org/martin/sources-composite.html) multiple tile sources into one
* Generate [sprites](https://maplibre.org/martin/sources-sprites.html) and [font glyphs](https://maplibre.org/martin/sources-fonts.html)
* Generate tiles in bulk from any Martin-supported sources into an MBTiles file with [martin-cp](https://maplibre.org/martin/martin-cp.html) tool
* Examine, copy, validate, compare, and apply diffs between MBTiles files with [mbtiles](https://maplibre.org/martin/tools.html#mbtiles) tool
