But Primal dosen't support group chat function. Doing fast search, it seems that Nostrord client is specifically made for nostr group chats. Probably there are some others too, like Chachi, Flotilla, 0xChat. Chachi — most user-friendly for beginners Chachi is a web-based NIP-29 group chat client with a clean, Telegram-like interface. It's widely considered the most accessible entry point for Nostr group chats. Just open it in a browser, no install needed. Flotilla — best for Discord-style communities Flotilla is modeled after Discord — groups function like Discord servers or Slack workspaces, where users join an entire group of chat rooms at once, rather than joining individual chat rooms one by one. No Bullshit Bitcoin It describes itself as "the decentralized Discord alternative built on the Nostr protocol." Flotilla Great if you want structured communities with multiple rooms. 0xChat — best for mobile/privacy-focused users 0xChat is a secured chatting app built on Nostr that prioritizes privacy, with features like private key login, encrypted private chats, and public channels. It is a free, open-source, non-profit project that does not collect any user data. Google Play Available on Android and iOS — good for people who want a mobile-first chat experience similar to Signal or Telegram. Nostrord — newest, most cross-platform Nostrord is built with Kotlin Multiplatform, meaning it runs as native apps on Android, iOS, desktop, and in the browser via WebAssembly — with over 90% shared code across all platforms. Nostrord Very new (launched April 2026), so less battle-tested but promising.
