Nostr (Notes and Other Stuff Transmitted by Relays) is an open, censorship-resistant, and decentralized communication protocol designed for simplicity and resilience. Unlike traditional platforms, Nostr doesn’t rely on centralized servers. It already supports various use cases with free, open-source clients—offering alternatives to platforms like Twitter/X, Meetup, Office365, Wikipedia, healthcare systems and more. We will help you get started with Nostr.
Since the initial commit in November 2019, Nostr has seen remarkable adoption and growth within the open-source community, evidenced by over 12,500 GitHub stars, 500+ forks, and contributions from more than 350 developers. The protocol has sparked the creation of an impressive ecosystem of over 390 projects, including mobile and web clients, relays, tools, and services that further enhance Nostr’s functionality. Bridges into other Social Networks like ActivityPub are also explored.
With over 70 tools and 48 libraries, developers can integrate Nostr into a wide array of applications—ranging from chat platforms to file storage and even decentralized marketplaces. These resources help to build censorship-resistant systems without the need for centralized servers. Whether you’re working on peer-to-peer markets, privacy-focused messaging apps, or decentralized social media, Nostr’s ecosystem offers the tools.
