Apple built the most powerful browser-based open source GIS without even intending it. I forked their Embedding-Atlas, added
@maplibre.org
support and now you have a WebGPU-ready GIS, table, graph and SQL support for 100M datasets! Have a look:

You can use three.js as GIS to render contour lines from a Geotiff with customizable labels! Work in progress. (P.S. can you tell where this might be? ;) )

I streamed 86M bluesky posts in my browser from their open jetstreams and naively mapped all mentioned Italian cities. Even though most of them are false positives, it was still a fun app to build!

It's a pity bluesky doesn't offer proper location tagging.

basemap canvas renderer from 2025? Yes it works π So if you have legacy systems running where you don't have the resources to upgrade you can still replace costly raster tile APIs.

After a couple of hours of fixing xcode-related errors I finally managed to bundle my basemap app for iOS. Using
@maplibre.org
,
@bkgbund.bsky.social
bund.bsky.social
free world vector tiles and
@komoot.bsky.social
Photon geocoder. Next is Android & a more advanced feature set.
