Reachlo SDK

Real-time infrastructure for AI streaming. Built to be radically cheaper than traditional real-time platforms.

Reachlo is a drop-in real-time backend designed for AI-first products. Whether you're streaming LLM tokens, building collaborative canvases, or syncing multi-agent systems, Reachlo handles the scale — without punishing per-message pricing.

Why Reachlo?

• ⚡ Built for AI Streaming Optimized for high-frequency, small-packet token streams from LLMs and agents.

• 💰 Bandwidth-Based Pricing Pay for data transfer, not messages. Streaming workloads are often up to 10× cheaper than event-based platforms.

• 🌍 Global Edge Architecture Designed for single-digit millisecond latency in most regions.

• 🛠️ Zero Config No brokers, no clusters, no tuning. Just an API key and you’re live.

Installation

npm install reachlo

Quick Start

1. Connect

Initialize the client using an API key from the Reachlo Dashboard.

import Reachlo from 'reachlo';

const client = new Reachlo('YOUR_API_KEY');
await client.connect();

2. Stream AI Responses

Ideal for ChatGPT-style typing effects and live AI output.

const stream = client.channel('ai-response-session-123');

// Subscribe to token updates
stream.subscribe((token) => {
  renderToUI(token);
});

// Publish tokens from your backend or agent
stream.publish("The ");
stream.publish("future ");
stream.publish("is ");
stream.publish("real-time.");
