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 end-to-end encryption. 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:

# 1. Download and start
mkdir -p /opt/synapsis && cd /opt/synapsis
curl -O https://raw.githubusercontent.com/cyph3rasi/synapsis/main/docker-compose.yml
curl -O https://raw.githubusercontent.com/cyph3rasi/synapsis/main/docker/Caddyfile
curl -O https://raw.githubusercontent.com/cyph3rasi/synapsis/main/docker/.env.example
cp .env.example .env

# 2. Edit .env with your domain and secrets (takes 2 minutes)
nano .env

# 3. Start your node
docker compose up -d

Done! Your node is live at https://your-domain.com with automatic SSL. No build step. No dependencies. No fuss.

Updating:

docker compose pull && docker compose up -d

For detailed Docker setup, see 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 — End-to-end encrypted 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	True E2E encrypted chat
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 (or MinIO for local dev)

Local Setup

# 1. Clone the repository
git clone https://github.com/cyph3rasi/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
npx drizzle-kit push

# 5. Run the development server
npm run dev

Visit http://localhost:3000 — the app will redirect you to /install for initial setup.
