Amethyst (Nostr Client)1.19.0

Amethyst (Nostr Client) lets people read and publish Nostr posts, follow conversations, exchange private messages, and participate in a social network they control. It provides a client interface for text notes, threaded discussions, profiles, relay connections, and references to other notes or Nostr addresses. The developer’s product page presents Amethyst as an Android Nostr client, while this cataloged release targets macOS and is intended for communication through Nostr.

Its protocol coverage includes NIP-01 basic events, NIP-04 and NIP-17 encrypted messaging, NIP-06 mnemonic key derivation, deletion requests, threads, relay information and authentication, proof of work, subject tags, metadata, delegated signing, remote signing, wallet connections, private-key encryption, and Android signer integration. It also supports NIP-21 URIs, NIP-27 references, unknown-event handling, external identities, versioned encrypted payloads, static public-key sites, vanish requests, chess PGN, relay lists, relay discovery and liveness, peer-to-peer orders, external content IDs, relay management, ecash mint discovery, application handlers, data vending machines, HTTP file storage, and Bluetooth Low Energy communications; NIP-07 browser signing is marked as not applicable.

Nostr users can use it for everyday conversations, following hashtags or custom hashtags, editing short notes, receiving push notifications through Google and Unified Push, and working with audio tracks from zapstr.live.

Version 1.17.0 is freeware for Apple Silicon (arm64) Macs. Its feature documentation also references building from source through BUILDING.md, while contribution work is associated with the project’s GitHub presence.
