'OpenFreeMap' is an open source map that can be self-hosted for free

If you want to display a custom map on your own website or application, you may have to go through tedious procedures such as registering on the site, creating a user database, and

paying a usage fee . However, ' OpenFreeMap ' provided by software engineer Zsolt Ero allows you to display custom maps for free and also allows you to self-host them.

Below is an example of the map that is actually displayed. The map displayed simply in black and white is 'Positron'.

'Bright' displays the map in color and also shows the names of buildings and other things.

'3D' allows you to see the map from a bird's-eye view, with buildings and other objects displayed in three dimensions. You can also rotate and change the angle of the map by right-clicking.

Another style, 'Liberty,' combines 'Bright' and '3D.' You can freely switch between a bird's-eye view and a bird's-eye view.

According to Ero, the map data used in OpenFreeMap is obtained from the

OpenStreetMap project, which creates open data geographic information. In addition, the use of the public instance is completely free, and there are no restrictions on the number of map views or requests. There is also no need for registration, use of API keys, or use of cookies, and the operating costs are covered through donations from users .

When integrating OpenFreeMap into a website or application, use the open source map library ' MapLibre GL JS '. To incorporate MapLibre GL JS into HTML, first install the 'maplibre-gl' package and load MapLibre GL JS JavaScript and CSS using the [script] and [link] tags in the [head] tag. This applies the map display functions and styles. You can also add controllers, markers, popups, etc. to the map and change its color as needed.

Detailed instructions on how to integrate OpenFreeMap are provided in the Quick Start Guide below.

OpenFreeMap is developed entirely as open source, including the setup of the production environment. Therefore, users can self-host or use public instances. The method of self-hosting is summarized on the following page.
