Naven
Communities
A neighbourhood group without a phone book
These groups are by definition people you do not know, and a link on a leaflet is a better front door than collecting numbers.
Who this is for
Street and estate groups of thirty to two hundred households.
How it is usually set up
A channel joined by a link distributed on paper through doors.
What Naven does not claim
Naven promises no security and no moderation. Messages are screened before they send against twelve published categories, by software written by one person — it misses things, and it is weaker in languages other than English. Calls are not screened at all. Naven is not end-to-end encrypted, which is what makes screening possible; anyone whose first requirement is end-to-end encryption should use Signal.
What it costs
Nothing. Naven is free, with no advertising, no paid tier and no data sale.
