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.

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

// 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 Your UI Responsive

When you're running vector searches on thousands of vectors or encrypting large messages, you don't want your app to freeze. Web Workers solve this by running heavy operations in background threads while your UI stays smooth.

The problem without workers:

// This blocks your UI - buttons won't click, animations freeze
const results = await vectorDB.search(query, k); // 100ms+ blocking

The solution with WorkerPool:

import { WorkerPool } from '@ruvector/edge/worker-pool';

// Create a pool of background workers (auto-detects CPU cores)
const pool = new WorkerPool(
  new URL('@ruvector/edge/worker', import.meta.url),
  new URL('@ruvector/edge/ruvector_edge.js', import.meta.url),
  { dimensions: 128, metric: 'cosine', useHnsw: true }
);

await pool.init(); // Workers load WASM in parallel

// Now searches run in background - UI stays responsive!
const results = await pool.search(queryVector, 10);

// Insert 10,000 vectors? Workers split the work automatically
const ids = await pool.insertBatch(largeDataset); // Parallel insertion

// Search multiple queries at once
const allResults = await pool.searchBatch(queries, 10); // Parallel search

What the Worker Pool does for you:

Feature	What It Means
Auto-scaling	Creates workers based on your CPU cores (2-8 typically)
Load balancing	Distributes work evenly across workers
Batch splitting	Large datasets are chunked and processed in parallel
Timeout handling	Stuck operations fail gracefully after 30 seconds
Error recovery	One failing worker doesn't crash your whole app

When to use workers:

Scenario	Use Workers?	Why
100+ vectors	Maybe	Small searches are fast enough inline
1,000+ vectors	Yes	Noticeable speedup from parallelism
10,000+ vectors	Definitely	3-4x faster with worker pool
Batch inserts	Yes	Don't block UI during data loading
Real-time search	Yes	Keep typing responsive during search
Mobile devices	Yes	Avoid UI jank on slower processors

Simple rule: If the operation takes more than 50ms, use a worker.

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

mkdir my-swarm && cd my-swarm
npm init -y
npm install @ruvector/edge

Create index.html:

<!DOCTYPE html>
<html>
<head><title>My AI Swarm</title></head>
<body>
  <div id="status"></div>
  <script type="module" src="swarm.js"></script>
</body>
</html>

---

Step 1: Agent Identity

Every agent needs a unique cryptographic identity. This enables signing messages and verifying authenticity.

Create swarm.js:

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.

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.

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.

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.

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

Option 1: WebRTC (Browser-to-Browser)

Best for: Direct browser-to-browser communication Cost: Free (need minimal signaling server)

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)

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)

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:

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)

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

# 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

Network Topologies - How agents connect to each other:

Topology	Best For	Description
Mesh	General purpose	Every agent can talk to every other agent directly
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
Nostr	~150ms	No	Decentralized social, simple pub/sub

Use Cases - Pre-built patterns for common scenarios:

Use Case	What It Does
AI Assistants	Multiple specialized agents handling different types of questions
Data Pipeline	Distributed ETL with parallel processing stages
Multiplayer Gaming	Real-time game state sync with authoritative host
IoT Swarm	Coordinate sensors and actuators across locations
Marketplace	Agents that negotiate, bid, and trade autonomously
Research Compute	Distribute calculations across many devices

Features - Building blocks you can mix and match:

Feature	What It Adds
Identity	Ed25519 cryptographic keypairs for each agent
Encryption	AES-256-GCM for all messages
HNSW Index	Fast similarity search (150x faster than brute force)
Semantic Matching	Route tasks to the best agent automatically
Raft Consensus	Elect leaders and agree on shared state
Post-Quantum	Future-proof signatures against quantum computers
Spiking Neural	Bio-inspired learning and pattern recognition
Compression	Adaptive bandwidth optimization (4-32x)

Exotic Patterns - Advanced capabilities for specialized needs:

Pattern	What It Does
MCP Tools	Browser-based Model Context Protocol for AI collaboration
Byzantine Fault	Tolerate malicious or faulty nodes
Quantum Resistant	Hybrid signatures safe from future quantum attacks
Neural Consensus	Use spiking networks for group decisions
Swarm Intelligence	Particle swarm optimization for problem solving
Self-Healing	Automatic failure detection and recovery
Emergent Behavior	Evolutionary algorithms for agent adaptation

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.

// 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
