# The zig-nostr ecosystem

zig-nostr is more than a library, it's a layered ecosystem for building on Nostr
in Zig. One audited core, shared by focused utility libraries and by real native
apps, so every layer benefits from the same well-tested foundation.

## Core library

**[`zig-nostr/nostr`](https://github.com/zig-nostr/nostr)**: secp256k1 keys and
BIP-340 signing, the NIP-01 event model, relay transport with the outbox model, a
zero-copy local-first store, and the NIP-46 signer protocol. It builds for macOS,
Linux and Windows, and its parsers are fuzzed. It's the credibility
anchor for everything else, and it keeps growing: more NIPs and capabilities land
with each milestone. See [NIP support](/nips) and the [architecture](/architecture).

## Utility libraries

Focused building blocks that layer on the core so apps don't reinvent the basics.
More arrive as the ecosystem grows, they'll be listed here as they ship.

## Native apps

Real products built entirely on the core, proof it holds up under product weight,
and the reason the ecosystem exists.

### Notary: shipped

A native NIP-46 signer for macOS and Linux: Zig, no Electron, no WebView. Your key lives in
a local daemon, nothing gets signed quietly, and your `nsec` never leaves it
unless you ask for it. On macOS it waits in the menu bar and shows its window only when a request needs a decision.

### Plaza: shipped

The flagship client: read without an account, post in four clicks, with the feed
rendered from disk and reconciled in the background. It opens long-form articles, searches for people by name, adds pictures from a file and covers notes marked sensitive. Your key lives in Notary, a separate
process, or in your own signer.

### deed: shipped

The nostr command line: keys, events, NIP-19 codes, NIP-44, signature checks, relays, a local store that later runs read without a network, and verbs for sync, private messages, a NIP-46 signer, Blossom and NIP-98. One binary of under 3 MB for macOS, Linux and Windows.

### On the roadmap

Plaza, Notary and deed are downloadable and keep growing. Next I am adding a C ABI with Swift bindings, Notary for Windows, `deed mcp`, and an app engine extracted from Plaza that new apps can build on. Private messages, zaps and a wallet, groups, searching notes and playing video remain later work in Plaza.

See the [roadmap](/roadmap) for what comes next, and for what is deliberately not being
built.
