Nostr Clients Compared — iOS, Android, Web & Desktop Apps
Compare open-source Nostr client apps across iOS, Android, web and desktop by platform, key-management/signer model and license. Your identity is your keypair, so you can switch clients freely. Free CSV/JSON + REST under CC BY 4.0.
Quick answer
A Nostr client is the app you actually use to read and post. The key insight: your identity is a keypair (your nsec), not an account on any server, so you can move between clients freely without losing your followers or history. This reference compares 19 open-source clients across iOS/macOS (Damus, Nostur, Nos), Android (Amethyst, Voyage), cross-platform mobile (Primal, YakiHonne, 0xchat, Olas), web (Coracle, Snort, Iris, noStrudel, Habla.news, Flycat, Ditto) and desktop (Gossip, Notedeck) by platform, key-management model and license.
Because identity lives in your keypair, switching clients is friction-free. Web clients lean on NIP-07 browser signers; Android increasingly uses NIP-55 external signers (Amber); desktop clients like Gossip encrypt your key on disk. Hold your own nsec and you stay sovereign across every app.
