Chorus
Chorus is a nostr relay.
It is pretty fast: docs/PERFORMANCE.md.
It can work as your personal relay: docs/PERSONAL_RELAY.md.
To deploy chorus, read docs/DEPLOYING.md
To configure chorus read docs/CONFIG.md
To undertand the relay's behavior, read docs/BEHAVIOR.md
To understand command line tools, read docs/TOOLS.md
Chorus does not have any provisions for charging users.
Chorus does not have any provisions for synchronizing events with other relays outside of the nostr protocol.
Alternatives

- Chorus has personal relay rules by default
- Chorus has extensive IP banning to protect your relay from abuse
- Chorus supports NIP-42 (AUTH), NIP-59 (GiftWrap), NIP-65 (Relay Lists) and PR 1030.
- Chorus has a moderation tool
