Implementation Status¶
Integrations¶
| Integration | Status |
|---|---|
| MapLibre Native | Supported since MapLibre Android 12.1.0 and MapLibre iOS 6.2.0. PR: #3246. |
| MapLibre GL JS | Supported since version 5.12.0. PR: #6570. |
| Planetiler | Can generate tiles in MLT since version 0.10.0. |
| PMTiles | Can store MLT; see PMTiles v3 spec - Tile Type. |
| Martin tile server | Can detect and serve MLT since version 1.3.0. PR: #2512. Can automatically convert between MLT and MVT depending on headers since version 1.9.0. See the docs. |
| QGIS plugin | Opens MLT files in QGIS via the Rust mlt parser. See qgis/README.md. |
| visgl/loaders.gl and module | Decodes MLT tilesets. Supported since version 4.4 via the pre-bundled mlt-decoder.cjs. |
Implementations¶
| Implementation | Language | Type | Notes |
|---|---|---|---|
| maplibre-tile-spec/cpp | C++ | Decoder | Used by MapLibre Native |
| maplibre-tile-spec/ts | TypeScript | Decoder / Encoder | Used by MapLibre GL JS. The encoder is still experimental. |
| maplibre-tile-spec/java | Java | Encoder | |
| maplibre-tile-spec/rust/mlt | Rust | Decoder / Encoder | The mlt CLI and TUI for inspecting and converting tiles, built on mlt-core. |
| maplibre-tile-spec/rust/mlt-core | Rust | Decoder / Encoder | The core library. Used in Martin. |
| maplibre-tile-spec/rust/mlt-wasm | Rust / WASM | Decoder | Uses mlt-core |
| maplibre-tile-spec/rust/mlt-py | Rust / PyO3 | Decoder / Encoder | Exposes mlt-core to Python via PyO3. |
| maplibre-tile-spec/rust/mlt-ffi | Rust / FFI | Decoder / Encoder | Foreign-function bindings for mlt-core, for Java/Kotlin, C++, and C. |
