Buzz

Aplicativo Descentralizado

A self-hostable chat/workspace platform, built on a Nostr relay, where humans and AI agents share the same rooms — messaging (NIP-01), authenticated presence (NIP-42, Schnorr-signature), git collaboration (NIP-34: patches, repo announcements, status events), and media (Blossom protocol) all ride the same relay. Publicly released by Block, Inc. (formerly Square) but explicitly not the internal-production version employees are told to use — see Capture Risk. Grew extremely fast for its age: repository created March 2026, already ~29,700 GitHub stars / ~3,800 forks by this story's drafting (August 2026). README frames it as under active development — some features (relay, channels, DMs, search) work today, others (mobile clients, approval gates) are in progress, and some (web-of-trust reputation, culture features) remain conceptual.

Aplicativo Descentralizado Atributos

Origens Human+AI-agent collaborative workspace — a Nostr-relay-based chat/coordination substrate designed for humans and AI agents to share rooms, extended with git-collaboration events (NIP-34)
Banco de Dados PostgreSQL (Nostr events, full-text search)
Linguagem de Consulta Nostr event subscription filters (relay protocol); SQL internally (Postgres)
Formatos de Dados Nostr events (NIP-01 core, NIP-34 git events, NIP-42 auth); Blossom media blobs (S3/MinIO-backed)
Edição Colaborativa em Tempo Real N/A
Edição de Texto Rico Likely (chat/workspace UI; not itemized in README)
Suporte Móvel In progress (README lists mobile clients as under development, not yet shipped)
Suporte Web Yes (React web frontend)
Aplicativos Nativos Yes (React + Tauri desktop app)
Termos Free / self-hostable (Apache-2.0); Block's own internal build is private and not the OSS release
Fundos Undisclosed (internal Block project, no separate funding round)
Baseado Em Nostr (NIP-01 core relay, NIP-42 Schnorr-signature auth, NIP-34 git-over-Nostr events, Blossom media protocol)
Categoria de Caso de Uso Team chat / workspace — humans and AI agents sharing rooms; secondary git-collaboration surface via NIP-34
Tipo de Interface de Usuário Web + native desktop (React, Tauri)
Capacidades Offline Not stated in README
Recursos de Colaboração Channels, DMs, search (working today per README); git patches/repo/status events via NIP-34; approval gates (in development)
Portabilidade de Dados High in principle — standard Nostr events (NIP-01/34/42), portable to any compliant relay/client; Blossom media likewise protocol-defined
Ecossistema de Integração Nostr ecosystem (any NIP-01/34/42/Blossom-compliant relay or client); shares the NIP-34 git-over-Nostr surface with this project's existing ngit entry, though the two are distinct products — ngit is a focused git CLI/frontend, Buzz is a general chat/workspace platform where git is one event type among several
Exportação de Dados da Web2 Not stated
Coerência Pró-social Mixed — open protocol foundation (Nostr) and Apache-2.0 license, but single-corporate-maintainer control and an explicit gated internal-vs-OSS split cut against full openness
Fluxos Econômicos No
Governança e Tomada de Decisão Centralized (Block, Inc. controls the roadmap and the OSS/internal split)
Mídia / Publicação Yes (Blossom media protocol for file/image sharing)
Gestão do Conhecimento Not a primary focus per README
Sensemaking Not stated
Gestão de Projetos Partial (git-workflow events via NIP-34: patches, PRs, status)
Modelo de Comunicação Real-time chat/channels/DMs, relay-mediated
Resiliência de Rede Depends on relay availability; self-hostable so not dependent on a single Block-run relay, but no stated multi-relay redundancy pattern (unlike ngit's explicit multi-git-server redundancy)
Mecanismo de Descoberta Nostr relay-based
Participantes Máximos Not stated
Soberania de Dados High if self-hosted (Apache-2.0, self-hostable via Docker Compose/Railway); low if using Block's own hosted/internal instance
