Vector tiles are an established format to publish highly interactive maps for use on mobile devices and desktop browsers. A benchmark compares MVT tile generation and tile serving performance of specialized servers like t-rex and proven map servers like UMN Mapserver.

WebAssembly is a binary runtime format designed for efficiency, speed and safety. Version 1.0, standardized in a W3C Working Group, is now supported by all major browsers.
