Martin is a tile server able to generate and serve [vector tiles](https://github.com/mapbox/vector-tile-spec) on the fly from large [PostGIS](https://github.com/postgis/postgis) databases, [PMTile](https://protomaps.com/blog/pmtiles-v3-whats-new) (local or remote), and [MBTile](https://github.com/mapbox/mbtiles-spec) files, allowing multiple tile sources to be dynamically combined into one. Martin optimizes for speed and heavy traffic, and is written in [Rust](https://github.com/rust-lang/rust).
Additionally, there are [several tools](https://maplibre.org/martin/tools.html) for generating tiles in bulk from any Martin-supported sources (similar to `tilelive-copy`), copying tiles between MBTiles files, creating deltas (patches) and applying them, and validating MBTiles files.
See [Martin book](https://maplibre.org/martin/) for complete documentation.
## Installation
_See [installation instructions](https://maplibre.org/martin/installation.html) in the Martin book._
**Prerequisites:** If using Martin with PostgreSQL database, you must install PostGIS with at least v3.0+, v3.1+ recommended.
You can download martin from [GitHub releases page](https://github.com/maplibre/martin/releases).

If you are using macOS and [Homebrew](https://brew.sh/) you can install `martin` and `mbtiles` using Homebrew tap.
```shell
brew tap maplibre/martin
brew install martin
```
## Running Martin Service
_See [running instructions](https://maplibre.org/martin/run.html) in the Martin book._
Martin supports any number of PostgreSQL/PostGIS database connections with [geospatial-enabled](https://postgis.net/docs/using_postgis_dbmanagement.html#geometry_columns) tables and tile-producing SQL functions, as well as [PMTile](https://protomaps.com/blog/pmtiles-v3-whats-new) and [MBTile](https://github.com/mapbox/mbtiles-spec) files as tile sources.
Martin can auto-discover tables and functions using a [connection string](https://maplibre.org/martin/pg-connections.html). A PG connection string can also be passed via the `DATABASE_URL` environment variable.
Each tile source will have a [TileJSON](https://github.com/mapbox/tilejson-spec) endpoint.
#### Examples
```shell
# publish all tables and functions from a single database
export DATABASE_URL="postgresql://user:password@host:port/database"
martin
# same as above, but passing connection string via CLI, together with a directory of .mbtiles/.pmtiles files
martin postgresql://user:password@host:port/database path/to/dir
# publish all discovered tables/funcs from two DBs
# and generate config file with all detected sources
martin postgres://... postgres://... --save-config config.yaml
# use configuration file instead of auto-discovery
martin --config config.yaml
```
#### Docker Example
_See [Docker instructions](https://maplibre.org/martin/run-with-docker.html) in the Martin book._
Martin is also available as a [Docker image](https://ghcr.io/maplibre/martin). You could either share a configuration file from the host with the container via the `-v` param, or you can let Martin auto-discover all sources e.g. by passing `DATABASE_URL` or specifying the .mbtiles/.pmtiles files.
```shell
export PGPASSWORD=postgres # secret!
docker run -p 3000:3000 \
-e PGPASSWORD \
-e DATABASE_URL=postgresql://user@host:port/db \
-v /path/to/config/dir:/config \
ghcr.io/maplibre/martin --config /config/config.yaml
```
## API
_See [API documentation](https://maplibre.org/martin/using.html) in the Martin book._
Martin data is available via the HTTP `GET` endpoints:
| URL | Description |
|-----------------------------------------|-----------------------------------------------|
| `/` | Status text, that will eventually show web UI |
| `/catalog` | List of all sources |
| `/{sourceID}` | Source TileJSON |
| `/{sourceID}/{z}/{x}/{y}` | Map Tiles |
| `/{source1},…,{sourceN}` | Composite Source TileJSON |
| `/{source1},…,{sourceN}/{z}/{x}/{y}` | Composite Source Tiles |
| `/sprite/{spriteID}[@2x].{json,png}` | Sprites (low and high DPI, index/png) |
| `/font/{font}/{start}-{end}` | Font source |
| `/font/{font1},…,{fontN}/{start}-{end}` | Composite Font source |
| `/health` | Martin server health check: returns 200 `OK` |
