Yes, it’s possible to use OpenStreetMap data, but “how” depends a lot on what you’re trying to do with it.
If you just want to display maps in an app or website, the simplest route is usually using a map rendering library (like Leaflet or OpenLayers) and then pulling tiles from an OpenStreetMap-based tile server. That gives you the visual map layer without having to process the raw data yourself.
If you need deeper integration (like routing, geocoding, or custom queries), then you typically rely on additional services built on top of OpenStreetMap data, because OSM itself is just the dataset. Things like search and routing aren’t part of the core map data and need separate tools or APIs.
One important detail is that if your usage becomes heavy or commercial, you shouldn’t rely on the public OSM tile servers directly. In that case you’d either self-host tiles or use a paid provider that’s compatible with OSM data.а
