The SAND Stack

Solid · ActivityPub · Nostr · DID

Personal sovereignty in one command

Quick Start · Features · Why SAND? · Roadmap

Quick Start

npm install -g sandymount
sandymount start

That's it. Your personal SAND server is running.

What is SAND?

Four protocols, one stack, total sovereignty:

| | Protocol | What You Get | |:---:|----------|--------------| | S | Solid | Personal data pod — files, profiles, apps | | A | ActivityPub | Federated social — Mastodon, Threads, WordPress | | N | Nostr | Censorship-resistant social — relays, zaps, keys | | D | DID | Decentralized identity — one key, every protocol |

Features

✅ Available Now

| Feature | Description | |---------|-------------| | Solid Pod | Full LDP server with WebID, Web Access Control, Solid-OIDC | | Nostr Relay | NIP-01 compliant, rate-limited, memory-efficient | | Git Server | Clone and push repos via HTTP with WebID auth | | DID Resolution | did:nostr → WebID, NIP-98 HTTP authentication | | Mobile Ready | Runs on Android/Termux, ~100MB RAM |

🔜 Coming Soon

| Feature | Description | |---------|-------------| | ActivityPub | Mastodon-compatible federation via FedBox | | Unified Identity | One keypair for Solid + AP + Nostr | | P2P Connectivity | No VPS required |

Installation

Any Platform

npm install -g sandymount
sandymount start

Android (Termux)

pkg install nodejs-lts
npm install -g sandymount pm2
pm2 start sandymount -- start
pm2 save

With Options

sandymount start --port 3000 --nostr --git

Modern UI (SolidOS UI)

sandymount start --solidos-ui

Uses a modern Nextcloud-style interface instead of the classic mashlib databrowser. Requires local mashlib and solidos-ui files. See solidos-ui for setup.

Endpoints

| Endpoint | Protocol | Description | |----------|----------|-------------| | / | Solid | Pod root, WebID profile | | /relay | Nostr | WebSocket relay (wss://) | | /relay/info | Nostr | NIP-11 relay metadata | | /.git | Git | Clone/push repositories | | /.well-known/webfinger | Discovery | WebFinger lookup |

Why SAND?

The Problem

| Your Life | Who Controls It | |-----------|-----------------| | Identity | Google, Apple, Facebook | | Files | Dropbox, iCloud, Drive | | Social | Twitter, Instagram, TikTok | | Followers | The platform |

The Solution

| SAND Protocol | What It Fixes | |---------------|---------------| | DID | You own your identity | | Solid | You own your data | | Nostr | You own your voice | | ActivityPub | You own your social graph |

The Vision

Your phone = Your server
Your key = Your identity
Your pod = Your data
Your relay = Your reach

Zero to sovereignty in 60 seconds.
