Hosted relays, a relay-first Android app, and an open-source relay engine.

Your feed, your community, your relay — and the tools to run and browse them. Hosted relays paid in sats, a relay-first Android app, and an open-source relay engine that runs on a server or in your pocket.

How a personal feed works

web-of-trust filter

wss://you.feeds.relay.tools

Outbox spidering

We crawl your follows' write relays so nothing they post slips past you — your client reads one relay.

Communities, too

Open or invite-tree communities with NIP-29 groups, moderation tiers and Blossom media hosting.

Your notes, backed up

Negentropy-syncs your entire authored history into a relay you control.

Pay with lightning

No email, no card, no account. Sign in with nostr, top up with sats.

Web-of-trust filtering

Spam scored against your social graph instead of a blocklist.

Reachable over Tor

The whole app and every relay can run as an onion service — no clearnet DNS required.
