Run unlimited AI agent swarms directly in browsers, edge devices, and serverless functions - with zero cloud costs.
RuVector Edge eliminates the need for expensive cloud infrastructure by enabling peer-to-peer AI coordination that runs entirely on the edge. Your agents communicate directly with each other using military-grade encryption, no central servers required.
import init, { WasmIdentity, WasmHnswIndex, WasmSemanticMatcher } from '@ruvector/edge';
await init();
// Agents run free - in browsers, workers, edge functions
const identity = WasmIdentity.generate();
const matcher = new WasmSemanticMatcher();
const vectorIndex = new WasmHnswIndex(128, 16, 200);

|---|---|
| Pay per API call | Free forever |
| Data leaves your network | Data stays local |
| Central point of failure | Fully distributed |
| Vendor lock-in | Open source |
| High latency (round-trip to cloud) | Sub-millisecond (peer-to-peer) |
| Limited by server capacity | Scales with your devices |
The Economics of Edge AI
Cloud AI Swarm (10 agents, 1M operations/month):
├── API calls: $500-2000/month
├── Compute: $200-500/month
├── Bandwidth: $50-100/month
└── Total: $750-2600/month

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 keypairagent_id()returns a unique identifier derived from the public keysign()creates a cryptographic signature proving the message came from this agentverify()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
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)
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}`);
});
Transport Comparison
| Transport | Latency | Offline | Complexity | Best For |
|---|---|---|---|---|
| WebRTC | ~50ms | No | Medium | Real-time, gaming |
| GUN.js | ~100ms | Yes | Low | General purpose |
| IPFS/libp2p | ~200ms | Partial | High | Content storage |
| Nostr | ~150ms | No | Low | Simple messaging |
Recommended: Start with GUN.js
npm install gun @ruvector/edge
GUN requires zero setup, works offline, and has a free public relay network.
Cost at Scale
| Scale | Transport | Monthly Cost |
|---|---|---|
| Any size | Public GUN relays | $0 (unlimited) |
| Any size | WebRTC + free STUN | $0 (P2P direct) |
| Heavy storage | IPFS Pinata free tier | $0 (1GB) |
| Enterprise | Self-hosted relay | $5-20 (small VPS) |
Key insight: You only pay for relay/signaling infrastructure, never for compute. The actual AI swarm logic runs on users' devices for free.
