alt Hacker NewsI am curious: is it called "tileless" because it uses tiles, but offline? Or does it somehow not use tiles?

IIRC it usually means it stores the vectors and draws it clientside.

There are no tiles. All geometry is loaded and rendered directly from an SQLite database on every render.
Geometry is stored as TWKB (Tiny Well-Known Binary) to reduce storage and transport size. During decoding, they do clever work using aggregate functions and reusing buffers across rows to reduce allocations.
There is real potential in the tech, but unfortunately little momentum behind it.
