Radius

Radius is a platform for finding and organizing local events and activities. Post what you are up for with a time and place, and people nearby who share that interest can join you. Takes 30 seconds, no commitment required. You can mark yourself as doing something soon and open to others, or just open to meeting people interested in the same thing. See what is happening in your city through recent activity: who joined, who scheduled an event, and which new groups formed. Create groups around shared interests, from Ruby developers in Taiwan to Bitcoin meetups in Chiang Mai. Each group has its own activity feed and event schedule. The interface shows Coffee, a run, a bike ride style posts with easy pace descriptions and casual vibes. Works for meetups, hobby groups, professional communities, and anyone looking to connect locally around shared interests. Free to use.
