Welcome to Scrawn

Scrawn is a billing infrastructure that lets you integrate usage-based billing into your application with a single function call.

Simple Integration

Track billable events, calculate usage, and handle payments - all with one line of code.

What is Scrawn?

Scrawn tracks user events, calculates usage, and handles payments - all behind a simple SDK. Instead of building billing logic yourself, you call event consumers and we handle the rest.

import { Scrawn } from '@scrawn/sdk';

const scrawn = new Scrawn({
  apiKey: process.env.SCRAWN_KEY!,
  baseUrl: process.env.SCRAWN_BASE_URL!
});

// That's it - track usage with one line
await scrawn.sdkCallEventConsumer({ 
  userId: 'uuid', 
  debitAmount: 69.69,
});

One line of code - That's all you need to start tracking billable events in your application.

Why Scrawn?

Single Line Integration

No complex billing logic. One function call tracks events, calculates usage, and triggers payments.

Usage-Based Billing

Charge users based on actual consumption. Track API calls and function invocations per user.

Built-in Admin Dashboard

Monitor events, manage API keys, and view analytics out of the box.

How It Works

Deploy Backend - Self-host the gRPC server with PostgreSQL
Install SDK - Add @scrawn/sdk to your application
Track Events - Call scrawn.sdkCallEventConsumer() whenever billable actions occur
Collect Payment - Call scrawn.collectPayment() when usage exceeds threshold
