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
  * [GeoJSON](https://maplibre.org/martin/sources-geojson/) files, converted to vector tiles on the fly
* [Passthrough](https://maplibre.org/martin/sources-passthrough/) tiles from an upstream HTTP tile server
* [Combine](https://maplibre.org/martin/sources-composite/) multiple tile sources into one
* Serve [styles](https://maplibre.org/martin/sources-styles/) and generate [sprites](https://maplibre.org/martin/sources-sprites/) or [font glyphs](https://maplibre.org/martin/sources-fonts/) on the fly
* Generate tiles in bulk from any Martin-supported sources into an `MBTiles` file with [martin-cp](https://maplibre.org/martin/martin-cp/) tool
* Examine, copy, validate, compare, and apply diffs between `MBTiles` files with [mbtiles](https://maplibre.org/martin/tools/#mbtiles) tool
