Geo-location for content showing

I am not sure if this is right Category to post in. If it’s not, Admins, feel free to relocate it.

I have more complicated question:

What are best programs (widgets) to use for geolocation? I’m making a website for dog-friendly places and would like to use the location of a visitor, to show nearby places.

And for showing a map, with POI

At the moment, I have CMS Collections for Category (type of location like Restaurant, Hotel…) And Collection for the postcode of a location.

My plan is to make the best UX for visitors. Don’t want to scare them with the difficulty of searching

ANY help would be MUCH appreciated :pray::pray:

Anyone? No one?
