Sovereign identity
Your identity is made of cryptographic keypairs that you create for free and keep yourself. It is not an account that a company can suspend. Nobody else can post as you, and nobody can take your name, your history, or your followers.
How identities workNo silos
You post to the world, not to a server. Every post goes to all the servers you use. If one shuts down or bans you, your audience can still reach you through the rest.
Run your own serverModeration you choose
No single company decides what you see. Each server sets its own policy, and you pick the servers whose moderation you trust. You can change your mind at any time without losing anything.
How moderation worksRecommendations that answer to you
Your feed is ranked for you, not for advertisers. Harbor is built so that you choose the recommendation engine, see why it recommended something, and tune it or swap it out.
