![Composable Nostr apps, not monoliths. A **Nostr Applet** — a **napplet** — is a small, sandboxed app that does one thing well. It runs inside a host **shell** and delegates signing, storage and relay access over a simple, typed message protocol — so apps stop rebuilding the same client, and every sensitive request is brokered by the shell.](https://m.stacker.news/145635)

A **napplet** is a sandboxed web app that runs inside a **shell**. The shell and napplet communicate over `postMessage` using a JSON envelope format (`{ type, ...payload }`) defined by NIP-5D. The napplet never touches `localStorage`, relay connections, or signing keys directly -- the shell proxies everything through NAP interfaces.
