Canonical: https://gisforweb.com/tools/flatgeobuf/

Binary geospatial vector format with fast streaming via HTTP range requests.

FlatGeobuf is a performant binary format for geospatial vector data, built on FlatBuffers. Its packed Hilbert R-tree index enables efficient spatial filtering and streaming of just the features you need over plain HTTP range requests — no server-side database required. Supported by GDAL, QGIS, PostGIS and popular JavaScript libraries.
