Fast displaying of maps is possible thanks to GPU-accelerated vector tile rendering. It originated as an open-source fork of [mapbox-gl-js](https://github.com/mapbox/mapbox-gl-js), before their switch to a non-OSS license in December 2020. The library's initial versions (1.x) were intended to be a drop-in replacement for the Mapbox’s OSS version (1.x) with additional functionality, but have evolved a lot since then. ## Getting Started Include the JavaScript and CSS files in the `` of your HTML file. ```html ``` Include the following code in the `` of your HTML file. ```html

``` Enjoy the map!

## Thank you Mapbox 🙏🏽 We'd like to acknowledge the amazing work Mapbox has contributed to open source. The open source community is sad to part ways with them, but we simultaneously feel grateful for everything they already contributed. `mapbox-gl-js` 1.x is an open source achievement that now lives on as `maplibre-gl`. We're proud to develop on the shoulders of giants, thank you Mapbox 🙇🏽‍♀️. Please keep in mind: Unauthorized backports are the biggest threat to the MapLibre project. It is unacceptable to backport code from mapbox-gl-js, which is not covered by the former BSD-3 license. If you are unsure about this issue, [please ask](https://github.com/maplibre/maplibre-gl-js/discussions)!
