## Free Self-Learning AI Swarms at the Edge
**Build and deploy self-optimizing AI agent swarms that run entirely in web browsers, mobile devices, and edge servers - without paying for cloud infrastructure.**
Imagine having dozens of AI agents working together - analyzing data, routing tasks, making decisions, and getting smarter with every interaction - all running directly in your users' browsers. No API costs. No server bills. No data leaving your network. That's what @ruvector/edge makes possible.
This library gives you everything you need to build distributed AI systems: cryptographic identity for each agent, encrypted communication between them, lightning-fast vector search for finding the right agent for each task, consensus protocols so your agents can coordinate without a central server, and self-learning neural networks that continuously optimize agent routing based on real-world outcomes. It's all compiled to a tiny 364KB WebAssembly binary that runs anywhere JavaScript runs.
**The key insight:** Instead of paying cloud providers to run your AI infrastructure, you use the computing power that's already there - your users' devices. Each browser becomes a node in your swarm. The more users you have, the more powerful your system becomes - and with built-in self-learning capabilities (LoRA fine-tuning, EWC++ continual learning, ReasoningBank experience replay), your swarm gets smarter over time while still costing you nothing.

### Choose Your Package
```bash
# Lightweight core (364KB) - P2P, crypto, vectors, consensus
npm install @ruvector/edge
# Full platform (8.4MB) - adds graph DB, SQL, neural routing, ONNX
npm install @ruvector/edge-full
```
### Using Both Together
```javascript
// Start with edge core
import init, { WasmIdentity, WasmHnswIndex } from '@ruvector/edge';
// Add full capabilities when needed
import { graph, rvlite, sona, dag } from '@ruvector/edge-full';
import onnxInit from '@ruvector/edge-full/onnx';
```
---
### Consensus Modes: Trusted vs Open
RuVector provides two coordination strategies for different deployment scenarios:
| Mode | Protocol | When to Use |
|------|----------|-------------|
| **Trusted Cohort** | Raft | Private teams, enterprise LANs, known membership, low churn |
| **Open Swarm** | Gossip + CRDT | Public networks, anonymous browsers, high churn, adversarial environments |
```javascript
// Trusted cohort (Raft) - stable team of 3-7 nodes
const raftNode = new WasmRaftNode('node-1', ['node-1', 'node-2', 'node-3']);
raftNode.start_election(); // Leader election for consistent state
// Open swarm (Gossip + CRDT) - dynamic browser mesh
const gossipNode = new WasmGossipNode(identity);
gossipNode.join_swarm(relayUrl); // Eventually consistent, Byzantine-tolerant
```
**Why two modes?** Raft assumes known membership and trusted nodes - perfect for your dev team or enterprise deployment. But a public browser swarm has nodes joining/leaving constantly and can't trust everyone. Gossip protocols with CRDTs handle this gracefully: no leader election, no membership tracking, eventual consistency that converges even with malicious actors.
---
### Web Workers: Keep the UI Responsive
Heavy operations (vector search, encryption, neural network inference) run in Web Workers to avoid blocking the main thread. The package includes a ready-to-use worker pool:
```javascript
import { WorkerPool } from '@ruvector/edge/worker-pool';
// Create worker pool (auto-detects CPU cores)
const pool = new WorkerPool(
new URL('@ruvector/edge/worker', import.meta.url),
new URL('@ruvector/edge/ruvector_edge_bg.wasm', import.meta.url),
{
poolSize: navigator.hardwareConcurrency,
dimensions: 384,
useHnsw: true
}
);
await pool.init();
// Operations run in parallel across workers
await pool.insert(embedding, 'doc-1', { title: 'Hello' });
await pool.insertBatch([
{ vector: emb1, id: 'doc-2' },
{ vector: emb2, id: 'doc-3' },
{ vector: emb3, id: 'doc-4' }
]);
// Search distributed across workers
const results = await pool.search(queryEmbedding, 10);
// Batch search (each query on different worker)
const batchResults = await pool.searchBatch([query1, query2, query3], 10);
// Pool statistics
console.log(pool.getStats());
// { poolSize: 8, busyWorkers: 2, idleWorkers: 6, pendingRequests: 0 }
// Clean up
pool.terminate();
```
**Worker Pool Features:**
- Round-robin task distribution with load balancing
- Automatic batch splitting across workers
- Promise-based API with 30s timeout
- Zero-copy transfers via transferable objects
- Works in browsers, Deno, and Cloudflare Workers
---
### Quick Start
```bash
npm install @ruvector/edge
```
```javascript
import init, { WasmIdentity, WasmHnswIndex, WasmSemanticMatcher } from '@ruvector/edge';
await init();
// Create agent identity
const identity = WasmIdentity.generate();
console.log(`Agent: ${identity.agent_id()}`);
// Vector search (150x faster)
const index = new WasmHnswIndex(128, 16, 200);
index.insert("agent-1", new Float32Array(128));
// Semantic task routing
const matcher = new WasmSemanticMatcher();
matcher.register_agent("coder", "rust typescript javascript");
const best = matcher.find_best_agent("write a function");
```

---
## Tutorial: Build Your First Swarm
This tutorial walks you through building a complete AI agent swarm that runs entirely in browsers with no backend.
### Prerequisites
```bash
mkdir my-swarm && cd my-swarm
npm init -y
npm install @ruvector/edge
```
Create `index.html`:
```html
My AI Swarm
```
---
### Step 1: Agent Identity
Every agent needs a unique cryptographic identity. This enables signing messages and verifying authenticity.
Create `swarm.js`:
```javascript
import init, { WasmIdentity } from '@ruvector/edge';
async function createAgent(name) {
await init();
// Generate Ed25519 keypair
const identity = WasmIdentity.generate();
console.log(`Agent: ${name}`);
console.log(` ID: ${identity.agent_id()}`);
console.log(` Public Key: ${identity.public_key_hex().slice(0, 16)}...`);
return identity;
}
// Create our agent
const myAgent = await createAgent("Worker-001");
// Sign a message to prove identity
const message = new TextEncoder().encode("I am Worker-001");
const signature = myAgent.sign(message);
console.log(` Signature: ${signature.slice(0, 8).join(',')}...`);
// Verify the signature
const isValid = myAgent.verify(message, signature);
console.log(` Valid: ${isValid}`); // true
```
**What's happening:**
- `WasmIdentity.generate()` creates an Ed25519 keypair
- `agent_id()` returns a unique identifier derived from the public key
- `sign()` creates a cryptographic signature proving the message came from this agent
- `verify()` checks if a signature is valid
---
### Step 2: Secure Communication
Agents need to encrypt messages so only intended recipients can read them.
```javascript
import init, { WasmIdentity, WasmCrypto } from '@ruvector/edge';
await init();
const crypto = new WasmCrypto();
// Agent A wants to send a secret message to Agent B
const agentA = WasmIdentity.generate();
const agentB = WasmIdentity.generate();
// Generate a shared secret key (in real app, use key exchange)
const sharedKey = crypto.generate_key();
// Agent A encrypts
const plaintext = new TextEncoder().encode(JSON.stringify({
task: "analyze_data",
payload: { dataset: "sales_2024.csv" }
}));
const ciphertext = crypto.encrypt(sharedKey, plaintext);
console.log(`Encrypted: ${ciphertext.length} bytes`);
// Agent B decrypts
const decrypted = crypto.decrypt(sharedKey, ciphertext);
const message = JSON.parse(new TextDecoder().decode(decrypted));
console.log(`Decrypted: ${message.task}`); // "analyze_data"
```
**Security features:**
- AES-256-GCM authenticated encryption
- Random nonce per message (replay protection)
- Ciphertext integrity verification
---
### Step 3: Vector Search
Agents need to find each other based on capabilities. HNSW enables fast similarity search.
```javascript
import init, { WasmHnswIndex } from '@ruvector/edge';
await init();
// Create index: 128 dimensions, M=16 connections, ef=200 search quality
const index = new WasmHnswIndex(128, 16, 200);
// Register agents with their capability embeddings
// (In production, use real embeddings from a model)
function mockEmbedding(weights) {
const vec = new Float32Array(128);
weights.forEach((w, i) => vec[i] = w);
return vec;
}
// Register specialized agents
index.insert("rust-expert", mockEmbedding([0.9, 0.1, 0.0, 0.0]));
index.insert("python-expert", mockEmbedding([0.1, 0.9, 0.0, 0.0]));
index.insert("ml-expert", mockEmbedding([0.0, 0.5, 0.9, 0.0]));
index.insert("devops-expert", mockEmbedding([0.0, 0.0, 0.2, 0.9]));
console.log(`Index size: ${index.len()} agents`);
// Find best agent for a Rust task
const rustTask = mockEmbedding([0.85, 0.1, 0.05, 0.0]);
const results = index.search(rustTask, 3);
console.log("Best agents for Rust task:");
results.forEach(([id, distance]) => {
console.log(` ${id}: distance=${distance.toFixed(3)}`);
});
// Output: rust-expert: distance=0.050
```
**Why HNSW?**
- O(log n) search instead of O(n)
- 150x faster than brute force at 10K+ vectors
- Memory-efficient graph structure
---
### Step 4: Task Routing
Route tasks to the best agent using semantic matching.
```javascript
import init, { WasmSemanticMatcher } from '@ruvector/edge';
await init();
const matcher = new WasmSemanticMatcher();
// Register agents with capability descriptions
matcher.register_agent("code-agent",
"rust typescript javascript python programming coding functions classes");
matcher.register_agent("data-agent",
"python pandas numpy data analysis statistics csv excel");
matcher.register_agent("devops-agent",
"docker kubernetes terraform aws deploy infrastructure cicd");
matcher.register_agent("writing-agent",
"documentation markdown readme technical writing blog");
console.log(`Registered ${matcher.agent_count()} agents`);
// Route tasks to best agent
const tasks = [
"Write a Rust function to parse JSON",
"Analyze the sales data in this CSV",
"Deploy the app to Kubernetes",
"Update the API documentation"
];
tasks.forEach(task => {
const best = matcher.find_best_agent(task);
console.log(`"${task.slice(0, 30)}..." → ${best}`);
});
// Output:
// "Write a Rust function..." → code-agent
// "Analyze the sales data..." → data-agent
// "Deploy the app to Kube..." → devops-agent
// "Update the API documen..." → writing-agent
```
**How it works:**
- LSH (Locality-Sensitive Hashing) creates semantic fingerprints
- Tasks are matched to agents by fingerprint similarity
- Sub-millisecond routing even with many agents
---
### Step 5: Distributed Consensus
When multiple agents need to agree on a leader or shared state, use Raft consensus.
```javascript
import init, { WasmRaftNode } from '@ruvector/edge';
await init();
// Create a 3-node cluster
const members = ["node-1", "node-2", "node-3"];
const node1 = new WasmRaftNode("node-1", members);
const node2 = new WasmRaftNode("node-2", members);
const node3 = new WasmRaftNode("node-3", members);
console.log(`Node 1 state: ${node1.state()}`); // "follower"
console.log(`Node 1 term: ${node1.current_term()}`); // 0
// Node 1 times out and starts election
const voteRequest = node1.start_election();
console.log(`Node 1 state: ${node1.state()}`); // "candidate"
console.log(`Node 1 term: ${node1.current_term()}`); // 1
// Simulate: Node 2 and 3 grant votes
// (In real app, send voteRequest over network, receive responses)
const granted1 = node1.receive_vote(true);
const granted2 = node1.receive_vote(true);
console.log(`Node 1 state: ${node1.state()}`); // "leader"
// Leader can now coordinate the swarm!
console.log("Leader elected - swarm can coordinate");
```
**Raft guarantees:**
- Only one leader at a time
- Leader election in 1-2 round trips
- Tolerates f failures in 2f+1 nodes
---
## P2P Transport Options
RuVector Edge provides the intelligence layer. You need a transport layer for agents to communicate. Here are your free options:
### Architecture Overview

│ @ruvector/edge (WASM) │
│ Identity, Crypto, HNSW, Semantic Matching, Raft, etc. │
└─────────────────────────────────────────────────────────────┘
│
Transport Layer (choose one)
│
┌─────────────────────┼─────────────────────┐
▼ ▼ ▼

│ WebRTC │ │ GUN.js │ │ IPFS/ │
│ (P2P) │ │ (P2P) │ │ libp2p │
└─────────┘ └─────────┘ └─────────┘
```
---
### Option 1: WebRTC (Browser-to-Browser)
**Best for:** Direct browser-to-browser communication
**Cost:** Free (need minimal signaling server)
```javascript
import init, { WasmIdentity, WasmCrypto } from '@ruvector/edge';
await init();
const identity = WasmIdentity.generate();
const crypto = new WasmCrypto();
// Create peer connection
const pc = new RTCPeerConnection({
iceServers: [{ urls: 'stun:stun.l.google.com:19302' }] // Free STUN
});
// Create data channel for agent messages
const channel = pc.createDataChannel('swarm');
channel.onopen = () => {
console.log('P2P connection established!');
// Send encrypted message
const key = crypto.generate_key(); // Exchange via signaling
const message = { type: 'task', data: 'analyze this' };
const encrypted = crypto.encrypt(key,
new TextEncoder().encode(JSON.stringify(message))
);
channel.send(encrypted);
};
channel.onmessage = (event) => {
const decrypted = crypto.decrypt(key, new Uint8Array(event.data));
const message = JSON.parse(new TextDecoder().decode(decrypted));
console.log('Received:', message);
};
// Signaling (exchange offer/answer via any method)
const offer = await pc.createOffer();
await pc.setLocalDescription(offer);
// Send offer to peer via signaling server, WebSocket, or even QR code
```
**Free signaling options:**
- PeerJS Cloud (free tier)
- Firebase Realtime Database (free tier)
- Your own WebSocket on Fly.io/Railway free tier
---
### Option 2: GUN.js (Decentralized Database)
**Best for:** Real-time sync, offline-first, no server needed
**Cost:** Completely free (public relay network)
```javascript
import init, { WasmIdentity, WasmSemanticMatcher } from '@ruvector/edge';
import Gun from 'gun';
await init();
const identity = WasmIdentity.generate();
const matcher = new WasmSemanticMatcher();
// Connect to public GUN relays (free!)
const gun = Gun(['https://gun-manhattan.herokuapp.com/gun']);
// Create swarm namespace
const swarm = gun.get('my-ai-swarm');
// Register this agent
swarm.get('agents').get(identity.agent_id()).put({
id: identity.agent_id(),
capabilities: 'rust typescript programming',
publicKey: identity.public_key_hex(),
online: true,
timestamp: Date.now()
});
// Listen for new agents
swarm.get('agents').map().on((agent, id) => {
if (agent && agent.id !== identity.agent_id()) {
console.log(`Discovered agent: ${agent.id}`);
matcher.register_agent(agent.id, agent.capabilities);
}
});
// Publish tasks
swarm.get('tasks').set({
id: crypto.randomUUID(),
description: 'Write a Rust function',
from: identity.agent_id(),
timestamp: Date.now()
});
// Listen for tasks
swarm.get('tasks').map().on((task) => {
if (task) {
const bestAgent = matcher.find_best_agent(task.description);
if (bestAgent === identity.agent_id()) {
console.log(`I should handle: ${task.description}`);
}
}
});
```
**Why GUN?**
- No server required - uses public relays
- Offline-first with automatic sync
- Real-time updates via WebSocket
- Already integrated in RuVector Edge (Rust side)
---
### Option 3: IPFS + libp2p
**Best for:** Content-addressed storage + P2P messaging
**Cost:** Free (self-host) or free tier (Pinata, Infura)
```javascript
import init, { WasmIdentity, WasmCrypto } from '@ruvector/edge';
import { createLibp2p } from 'libp2p';
import { webSockets } from '@libp2p/websockets';
import { noise } from '@chainsafe/libp2p-noise';
import { gossipsub } from '@chainsafe/libp2p-gossipsub';
await init();
const identity = WasmIdentity.generate();
const crypto = new WasmCrypto();
// Create libp2p node
const node = await createLibp2p({
transports: [webSockets()],
connectionEncryption: [noise()],
pubsub: gossipsub()
});
await node.start();
// Subscribe to swarm topic
const topic = 'my-ai-swarm';
node.pubsub.subscribe(topic);
node.pubsub.addEventListener('message', (event) => {
if (event.detail.topic === topic) {
const message = JSON.parse(new TextDecoder().decode(event.detail.data));
console.log('Received:', message);
}
});
// Publish to swarm
node.pubsub.publish(topic, new TextEncoder().encode(JSON.stringify({
from: identity.agent_id(),
type: 'announce',
capabilities: ['rust', 'wasm']
})));
```
**IPFS for artifacts:**
```javascript
import { create } from 'ipfs-http-client';
// Use free Infura IPFS gateway
const ipfs = create({ url: 'https://ipfs.infura.io:5001' });
// Store agent output
const result = await ipfs.add(JSON.stringify({
task: 'analyze-data',
output: { summary: '...' },
agent: identity.agent_id(),
signature: identity.sign(...)
}));
console.log(`Stored at: ipfs://${result.cid}`);
// Share CID with swarm - anyone can fetch
```
---
### Option 4: Nostr Relays
**Best for:** Simple pub/sub with free public infrastructure
**Cost:** Free (many public relays)
```javascript
import init, { WasmIdentity } from '@ruvector/edge';
import { relayInit, getEventHash, signEvent } from 'nostr-tools';
await init();
const identity = WasmIdentity.generate();
// Connect to free public relay
const relay = relayInit('wss://relay.damus.io');
await relay.connect();
// Create Nostr event (signed message)
const event = {
kind: 29000, // Custom kind for AI swarm
created_at: Math.floor(Date.now() / 1000),
tags: [['swarm', 'my-ai-swarm']],
content: JSON.stringify({
agentId: identity.agent_id(),
type: 'task',
data: 'Write a function'
})
};
// Sign with identity (Nostr uses secp256k1, so bridge needed)
// Or use Nostr's native keys alongside RuVector identity
// Subscribe to swarm events
const sub = relay.sub([
{ kinds: [29000], '#swarm': ['my-ai-swarm'] }
]);
sub.on('event', (event) => {
const message = JSON.parse(event.content);
console.log(`From ${message.agentId}: ${message.type}`);
});
```

## Interactive Swarm Generator
Don't know where to start? We've included an interactive code generator that helps you build swarm configurations visually. Just select your options and get production-ready code instantly.
### How to Use the Generator
```bash
# Option 1: Use a local server (recommended)
npm install @ruvector/edge
npx serve node_modules/@ruvector/edge/
# Then open http://localhost:3000/generator.html
# Option 2: Open directly in browser
# Navigate to: node_modules/@ruvector/edge/generator.html
```
The generator runs live demos directly in your browser using the actual WASM library - you can test everything before copying the code.
### What You Can Configure

| **Star** | Centralized control | All agents connect through one coordinator |
| **Hierarchical** | Large organizations | Tree structure with managers and workers |
| **Ring** | Sequential processing | Messages pass around in a circle |
| **Gossip** | Eventual consistency | Information spreads like rumors |
| **Sharded** | Domain separation | Different groups handle different topics |
**Transport Layers** - How messages travel between agents:
| Transport | Latency | Offline? | Best For |
|-----------|---------|----------|----------|
| **GUN.js** | ~100ms | Yes | Getting started, offline-first apps |
| **WebRTC** | ~50ms | No | Real-time gaming, video, low latency |
| **libp2p** | ~200ms | Partial | IPFS integration, content addressing |

### Browser-Based MCP Tools
The generator includes a complete MCP (Model Context Protocol) implementation that runs entirely in the browser. This lets you create AI tools that work with Claude and other MCP-compatible systems, but without needing a server.
```javascript
// Create a browser-based MCP server
const mcp = new BrowserMCPServer();
await mcp.init();
// Built-in tools ready to use:
// - discover_agents: Find the right agent for a task
// - send_secure_message: Encrypted P2P communication
// - store_memory: Save vectors for semantic search
// - search_memory: Find similar items by meaning
// - sign_message: Cryptographically prove authorship
// Example: Route a request to find coding help
const response = await mcp.handleRequest({
method: 'tools/call',
params: {
name: 'discover_agents',
arguments: { query: 'help me write a Python script' }
}
});
// Connect multiple MCP servers for collaboration
const network = new MCPCollaborativeNetwork();
await network.addServer('coder', 'programming development');
await network.addServer('analyst', 'data analysis statistics');
await network.addServer('writer', 'documentation technical writing');
// Requests automatically route to the best server
const result = await network.routeRequest(request);
```
**Why browser-based MCP?**
- No server costs - runs on user devices
- Works offline - all tools available without internet
- Privacy-first - sensitive data never leaves the browser
- Instant deployment - just include the library
