[← SDKs](https://aioproductos.com/product/sdks)  · Your backend - Node 18+

## Node SDK: a whole product, included.

Elsewhere this is server-side event capture from a CDP. Here it ships on every plan - never an add-on, never metered.

The short answer Identity-first backend events, straight from your server to the spine: signup, payment, subscription change, churn. Zero dependencies, Node 18 or newer. Because the server knows who the user is, these events arrive with identity attached and join the same customer record as web, product, and mobile data.

Published by [AIOProductOS](https://aioproductos.com/product), the product management operating system for B2B SaaS teams. It joins customer feedback, revenue, delivery work, and code on one customer record, so teams prioritize by who is paying, not just what is loudest. [Who builds it, and how we work](https://aioproductos.com/about).

[Get your product key](https://platform.aioproductos.com/signup) [Open the live demo](https://platform.aioproductos.com/demo)

npm install, then send events.

```
npm install @aioproductoscom/node import { ProductOS } from "@aioproductoscom/node"; const pos = new ProductOS({ productKey: "pk_live_..." }); pos.track({ userId: "u_123", event: "subscription_started" });
```

Zero dependencies, Node 18+

What it does

### What the Node SDK captures

- Commercial events
  
  The lifecycle your billing system sees - signup, payment, subscription, churn - captured where it actually happens.
- Identity attached
  
  Server-side events carry the real user id by construction; no anonymous guessing to resolve later.
- Zero dependencies
  
  One package, no transitive surface to audit, Node 18 or newer.

### Why it beats the standalone version

Backend events are the revenue half of the join: when subscription_started from your server and feature usage from the app land on the same record, 'which paying accounts adopted what we shipped' stops needing a data team.

### Where it stops, honestly

It captures and sends; it does not run your billing. The billing join on the spine comes from connectors (Stripe and peers) plus these events - the SDK is how your own backend's view of the customer reaches the record.

FAQ

### The Node SDK, answered

**What should I send from the server?**

The commercial lifecycle your backend already knows: signup, payment, subscription change, churn. Those events arrive with a real user id attached, which is what lets in-app usage and revenue land on the same customer record.

**What are the requirements?**

Node 18 or newer, and zero dependencies. Install the package, construct the client with your product key, and call track.

**Does this replace my billing connector?**

No. The billing connectors sync subscription state; the Node SDK is how your own backend's view of the customer reaches the spine. Most teams run both.

## Why AIOProductOS

- **One MCP over the whole product spine, not one tool.** 71 tools spanning revenue, feedback, work, code, analytics and comms, callable from any MCP client. Competing MCP servers expose a single product's own data; this one answers across the join, and it is listed on the official MCP registry.
- **Connected, not consolidated.** 100+ connectors land Stripe, GitHub, your feedback tool and the rest onto one shared record, so a product question is a join instead of a reconciliation. You keep the tools you already run.
- **Flat plans, not a per-head meter.** Member counts are allowances, not per-seat billing, and AI teammates are included rather than metered per credit. Compare the real number for your team with the [stack cost calculator](https://aioproductos.com/tools/saas-stack-cost-calculator).
- **Nothing is plan-gated.** Every tier ships every module. The only limits are seats and agents, so the cheapest plan is the whole product.
- **Your data stays yours.** EU or US residency chosen at signup, bring your own model key, full-org GDPR export on every tier, and we never train on your data.
- **Honest onboarding.** A 7-day free trial, no credit card required, then a 30-day money-back guarantee on the first payment. The trial is gated on time only - never a credit meter on your tokens.

- **Local:** `npx -y @aioproductoscom/mcp@latest`
- **No credentials at all:** started without a `PRODUCTOS_TOKEN`, it runs in demo mode, read-only, against a fully seeded showcase workspace. Ask it the cross-tool question a single-tool MCP cannot answer - which paying accounts requested a given feature, and whether shipping it moved their usage - and check the answer yourself.
