Make the internet feel open again
Better community spaces for the open web.
Substr brings decentralized Nostr identity and relay-native content into community spaces that feel more open, less controlled, and easier to belong to.
Identity
Use the same Nostr identity across Substr and other clients, with access that stays yours.
Content
Posts, replies, and zaps stay relay-native, while Substr helps shape them into clearer shared conversations.
