Quick Start

React/Next.js

import { Databuddy } from "@databuddy/sdk/react";

export default function RootLayout({ children }) {
  return (
    <html>
      <body>
        {children}
        <Databuddy
          clientId={process.env.NEXT_PUBLIC_DATABUDDY_CLIENT_ID}
          trackWebVitals
          trackErrors
          trackPerformance
        />
      </body>
    </html>
  );
}

Node.js Server-Side

import { Databuddy } from "@databuddy/sdk/node";

const client = new Databuddy({
  clientId: process.env.DATABUDDY_CLIENT_ID,
  enableBatching: true,
});

await client.track({
  name: "api_call",
  properties: { endpoint: "/users", method: "GET" },
});

// Important: flush before process exit in serverless
await client.flush();

Feature Flags

import { FlagsProvider, useFlag, useFeature } from "@databuddy/sdk/react";

// Wrap your app
<FlagsProvider clientId="..." user={{ userId: "123" }}>
  <App />
</FlagsProvider>

// In components
function MyComponent() {
  const { on, loading } = useFeature("dark-mode");
  if (loading) return <Skeleton />;
  return on ? <DarkTheme /> : <LightTheme />;
}

LLM Analytics

import { databuddyLLM } from "@databuddy/sdk/ai/vercel";
import { openai } from "@ai-sdk/openai";

const { track } = databuddyLLM({
  apiKey: process.env.DATABUDDY_API_KEY,
});

const model = track(openai("gpt-4o"));
// All LLM calls are now automatically tracked

Common Patterns

Disable in Development

<Databuddy
  disabled={process.env.NODE_ENV === "development"}
  clientId="..."
/>

Skip Sensitive Paths

<Databuddy
  clientId="..."
  skipPatterns={["/admin/**", "/internal/**"]}
  maskPatterns={["/users/*", "/orders/*"]}
/>

Custom Event Tracking

// Browser
import { track } from "@databuddy/sdk/react";

track("purchase", {
  product_id: "sku-123",
  amount: 99.99,
  currency: "USD",
});

// Node.js
await client.track({
  name: "subscription_renewed",
  properties: { plan: "pro", amount: 29.99 },
});

Global Properties

// Browser
window.databuddy?.setGlobalProperties({
  plan: "enterprise",
  abVariant: "checkout-v2",
});

// Node.js
client.setGlobalProperties({
  environment: "production",
  version: "1.0.0",
});

REST API

Base URLs

ServiceURLPurpose
Analytics APIhttps://api.databuddy.cc/v1Query analytics data
Event Trackinghttps://basket.databuddy.ccSend custom events

Authentication

Use API key in the x-api-key header:

curl -H "x-api-key: dbdy_your_api_key" \
  https://api.databuddy.cc/v1/query/websites

Get API keys from: Dashboard → Organization Settings → API Keys

Query Analytics Data

curl -X POST -H "x-api-key: dbdy_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "parameters": ["summary", "pages"],
    "preset": "last_30d"
  }' \
  "https://api.databuddy.cc/v1/query?website_id=web_123"

Available Query Types:

TypeDescription
summaryOverall website metrics and KPIs
pagesPage views and performance by URL
trafficTraffic sources and referrers
browser_nameBrowser usage breakdown
device_typesDevice category breakdown
countriesVisitors by country
errorsJavaScript errors
performanceWeb vitals and load times
custom_eventsCustom event data

Date Presets: today, yesterday, last_7d, last_30d, last_90d, this_month, last_month

MCP (Model Context Protocol)

Databuddy exposes an MCP server for AI agents (Cursor, Claude Desktop, etc.) to query analytics. Use for natural-language questions, automated reports, or structured data extraction.

Endpoint: POST https://api.databuddy.cc/v1/mcp (local: http://localhost:3001/v1/mcp)

Auth: API key with read:data scope via x-api-key or Authorization: Bearer <key>

Tools:

  • ask – Natural-language analytics questions (e.g. "top 5 pages last week")
  • list_websites – List accessible website IDs
  • get_data – Pre-built query with websiteId, type, and preset or from/to
  • get_schema – ClickHouse schema docs (tables, columns)
  • capabilities – Query types with descriptions, date presets, hints

Date presets for get_data: last_7d, last_30d, last_90d, today, yesterday, this_week, this_month, etc.

Cursor setup (mcp.json): Add a Databuddy MCP entry with the API URL and your API key.

Send Events via API

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "type": "custom",
    "name": "purchase",
    "properties": {
      "value": 99.99,
      "currency": "USD"
    }
  }' \
  "https://basket.databuddy.cc/?client_id=web_123"

Batch Events

curl -X POST \
  -H "Content-Type: application/json" \
  -d '[
    {"type": "custom", "name": "event1", "properties": {...}},
    {"type": "custom", "name": "event2", "properties": {...}}
  ]' \
  "https://basket.databuddy.cc/batch?client_id=web_123"
