Gregory's Server@antanicus @scy There has been an interesting talk on #cccamp23 with a similar but different approach: https://media.ccc.de/v/camp2023-57248-freie_interaktive_karten_mit_versatiles
They are also mentioning protomaps AFAIK and the reason why they choose another solution.
@sercxanto @antanicus Thanks for the pointer. It’s a nice project, but it requires custom server software.
