Emerged finds new products worth a look, daily — what’s new today
For an organiser tired of Meetup's per-group fee, Radius gives you RSVPs, waitlists, a calendar feed and an API for nothing, plus a casual 'anyone up for this at 10?' post that needs no group.
Radius is a web platform for finding and running local communities: groups by interest, scheduled events, and a lighter thing it calls activities, where anyone can propose a bike ride and coffee at ten and let others vote on the time. Free groups get API access, embeddable widgets, calendar subscriptions, guest RSVPs and waitlists; Pro groups are £12 a month. There is deliberately no member-to-member messaging, only public comments and organiser broadcasts. Built on Rails by a founder who relaunched after a first Show HN drew 150 comments. Live in several cities, but early and thin elsewhere.
