A free Maplibre and Mapbox GL basemap style for everyone with complete liberty to use and self host. OSM Liberty is a fork of OSM Bright based on free data sources with a mission for a clear good looking design for the everyday user. It is based on the vector tile schema of OpenMapTiles.
Preview OSM Liberty with Maputnik
You can use the style in your Maplibre and Mapbox GL maps.
By default, the vector tiles are served from Maptiler Cloud and the relief shading, glyphs and sprites directly from GitHub. You would need to create a MapTiler account to get an access key and replace the placeholder {key} for the vector source with your own key.
Other options are:
- Create your own vector tiles with OpenMapTiles and host the tiles yourself for complete liberty.
- Use another vector tile source that is based on the vector tile schema of OpenMapTiles
- OpenMapTiles as vector data source
- Natural Earth Tiles for relief shading
- Maki as icon set
- Orange Mug as font glyphs
The map design originates from OSM Bright but strives to reach a unobtrusive and clean design for everyday use. Colored relief shading from Natural Earth make the low zoom levels look good.
You can edit the style directly online in Maputnik.
This style actually triggered the need for the development of Maputnik.
A pre-commit hook is included to validate and format the JSON styles using
maplibre-gl-style-spec.
To use, just install the NPM dev dependencies:
npm install
and then validate or format the style with
npm run validate
npm run format
Validation and reformatting will happen automatically on commit if you have the dependencies installed.
A Maki icon set using colors to distinguish between icon categories.
Maki is a living project and adds new icons over time, which means that there
could be new icons that OSM Liberty could use for POIs. sources_list.py is a
simple script to list both the names in OSM Liberty's iconset that don't map to
any valid Maki name, and the Maki names that are not currently used in OSM
Liberty's iconset. You can run the script with python3 sources_list.py.

Modify Icons
When submitting a PR, no need to include the sprites. They will be automatically created when merging a PR.
The size 11 icons are included in the sprites for backward compatability. Please don't include new size 11 icons.
- Take the
iconset.jsonand import it to the Maki Editor. - Apply your changes and download the icons in SVG format and the iconset in JSON format. Save the downloaded SVGs from Maki Editor to the folder svgs_iconset.
- Mandatory if the updated
iconset.jsonshould become part of this repo: Format the JSON withcat iconset.json | jq -MS '.'for better legibility. - There are also SVGs in the folder svgs_not_in_iconset. These are the SVGs for road shields, the dot used for city and town layers and the road area pattern which could not be modified using the Maki Editor. To modify these you could use e.g. Inkscape.
- Generate the low and high resolution sprites:
npm run build_sprites
