# Synapsis

**Your node. Your network. Your identity.**

Synapsis is an open-source, federated social network built for the decentralized web. Run your own node, own your identity with DIDs, and communicate across the Swarm network with plain text server-stored messaging. No corporations. No lock-in. Just you and the network.

---

## 🚀 Deploy Your Own Node (5 Minutes)

Run your personal Synapsis node with a single command:

```bash
# 1. Bootstrap the deployment directory
curl -fsSL https://synapsis.social/install.sh | bash

# 2. Edit /opt/synapsis/.env with your domain and admin email
nano /opt/synapsis/.env

# 3. Start your node
cd /opt/synapsis
docker compose up -d
```

Done! Your node is live at `https://your-domain.com` with automatic SSL. No build step. No dependencies. No fuss.
Database migrations run automatically on startup and during updates.

**Updating (migrations run automatically):**
```bash
docker compose pull && docker compose up -d
```

For detailed Docker setup, see [docker/README.md](docker/README.md).

## 🏗️ Architecture

Synapsis differs from traditional social networks by prioritizing **sovereign identity** and **native peer-to-peer communication**.

### 🔐 Decentralized Identity (DIDs)

Unlike centralized platforms where your identity is a row in a database owned by a corporation, Synapsis uses a cryptographic identity system:

| Concept | Description |
|---------|-------------|
| **DID** | A unique, cryptographically-generated identifier (`did:key:...`) assigned to every user. This is your true identity that exists independently of any server. |
| **Handle** | A human-readable username (`@alice`) that points to your DID. Think of it like a domain name pointing to an IP address. |
| **Key Pair** | Every account has a public/private key pair. Your private key proves you are you; your public key lets others verify your identity. |

**Why this matters:**
- **Ownership** — Your identity is cryptographically yours, not controlled by a company
- **Authenticity** — Every post is signed with your private key, proving it came from you
- **True Portability** — Move your account between nodes without losing followers

### 🌐 The Swarm Network

Synapsis operates on the **Swarm** — a native peer-to-peer network designed specifically for Synapsis nodes:

- **Gossip Protocol** — Nodes discover each other automatically and exchange information
- **Swarm Timeline** — Aggregated feed of posts from across all Synapsis nodes
- **Swarm Chat** — Direct messaging between users on any Synapsis node
- **Handle Registry** — Distributed directory of user handles across the swarm
- **Instant Interactions** — Likes, reposts, follows, and mentions delivered in real-time

### 🆚 Synapsis vs. Traditional Federation

| Feature | Traditional Federation | Synapsis |
|---------|------------------------|----------|
| **Identity** | Server-bound (`@user@server`) | DID-based (cryptographic, portable) |
| **Account Migration** | Limited (followers don't auto-migrate) | **Full** — DID-based migration with auto-follow |
| **Cryptographic Signing** | HTTP Signatures only | Full post signing with user keys |
| **Direct Messages** | Posts with limited visibility | Direct messaging between users |
| **Network Discovery** | Manual server discovery | Automatic gossip protocol |
| **AI Bots** | Not supported | Native bot framework with LLM integration |
| **Interactions** | Queue-based, delayed | Instant delivery via Swarm |

## 🛠️ Development

Want to hack on Synapsis? Here's how to run it locally:

### Prerequisites
- Node.js 20+
- PostgreSQL 15+
- S3-compatible storage (AWS S3, Cloudflare R2, Backblaze B2, Wasabi, or Contabo)

### Local Setup

```bash
# 1. Clone the repository
git clone https://github.com/GnosysLabs/Synapsis.git
cd synapsis

# 2. Install dependencies
npm install

# 3. Configure environment
cp .env.example .env
# Edit .env with your local database and storage settings

# 4. Set up the database
npm run db:push

# 5. Run the development server
npm run dev
```

Visit `http://localhost:3000` and register with an email listed in `ADMIN_EMAILS`. Local setup no longer uses a dedicated `/install` route.

### Tech Stack

- **Framework** — [Next.js 15+](https://nextjs.org/) (App Router)
- **Database** — PostgreSQL with [Drizzle ORM](https://orm.drizzle.team/)
- **Styling** — Tailwind CSS v4 & custom Vercel-like design system
- **Authentication** — Auth.js (NextAuth)
- **Type Safety** — TypeScript
