I can't believe they still haven't added a 2x pixel density version of the default map style. It's $CURRENTYEAR and we all have high pixel density phones. No one uses 1080p displays anymore. The default blurry version makes any page using OSM feel amateur.
We don't offer 2x raster tiles because we simply don't have the resources to do it while keeping the tiles minutely updated and open access. We serve around 60k req/sec on a tiny donation backed budget.
The raster tiles are primarily for our OSM mappers to see their map changes rendered quickly to improve the feedback loop.
Raster tiles hosted at tile.openstreetmap.org are not intended for widespread production use, they’re principally for mapper feedback. If you have a business need for something that doesn’t look “amateur” you should arguably be using a third party OSM-based service or hosting your own tiles.
