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
