The original Couchsurfing community turned for-profit in 2011 and lost the thing that made it work; this is the same idea rebuilt by volunteers as a registered non-profit with a charter that says no individual or organisation may ever take profit from it. Hosts, travellers and meet-ups in more than 180 countries, references and verification rebuilt from scratch, the code open source, and no paywall of any kind. You sign up as a host, a coucher, or just to find who is meeting up nearby.
