Edit the Style locally

If you want to edit the style locally with the Maputnik CLI, clone one of the OpenMapTiles styles GitHub repository. On Styles page you can find a list of styles with a preview.

In our example, we will use the Positron style. Clone the repository containing the style JSON file using following command:

git clone

Now start Maputnik and tell the programm to watch the style.json file for changes. Any time you change something in Maputnik, it will also save the changes to the style.json file. You can even manually edit the style.json file in your favorite text editor and then reload Maputnik to see the result.

To start with edit, run Maputnik and visit http://localhost:8000 in your browser to access the editor.

maputnik --watch --file style.json
