It’s not a perfect replacement, but searching OpenStreetMap via https://overpass-turbo.eu/ with a query like
[out:json][timeout:25];
(
nwr["diet:vegan"~"yes|only"]({{bbox}});
nwr["cuisine"~"vegan"]({{bbox}});
);
out geom;
can be useful and is often more up-to-date with respect to restaurants that actually still exist.

I’ve build a platform initially based on OSM imports. It’s good to have it, but the data quality is not reliable enough. I keep researching and cleaning up the data + working on repeatable import from OSM + OSM enrichment, but it’s quite tricky on a scale. Mapped ~50k vegan and vegan-friendly places so far and everyone can add/save their favourite places, add reviews etc. All free, no ads and run by 2 people. And mobile app is available - maybe this will be another optional alternative to consider :)
