alt Hacker NewsBuilding https://birding.live/ a birding site, that helps people look up bird sightings in their area, specifically those classed as rare. Connects to a whole lot of open data sources (eBird, OSM, Nominatim etc.)
Will remain free, planning to add some kindof mailing list for alerts when birds are spotted in areas of interest.
Really like this! It's telling me a rare sighting of a caspian gull near home, makes me want to leave work early and check it out.
