# Amplitude Quickstart > For AI agents: a documentation index is available at [/docs/llms.txt](/docs/llms.txt). Append `.md` to any page URL for markdown, or send `Accept: text/markdown`. Amplitude is quick to set up. Most implementations take under 10 minutes from install to seeing your first events. Pick your platform below and follow a few steps. Not finding your platform? [Browse all Amplitude SDKs](https://amplitude.com/docs/sdks). ## Pick your platform #### JavaScript Amplitude offers several ways to instrument a JavaScript web app. Choose the method that fits your workflow. #### Snippet ### Install the Browser SDK with a snippet Paste-and-go install for websites. Add this script to the `` of your site when you want the fastest possible browser install with no build step or npm package. > **Tip:** Set up with a browser snippet > > Use this option for static sites, CMS-driven sites, or any project where a script tag is easier than an SDK install. Script-tag install with no bundler. [Autocapture](https://amplitude.com/docs/data/autocapture) and [Session Replay](https://amplitude.com/docs/session-replay). Remote config for feature flags. 1. **Paste the snippet into your site's \`\`** Add it to every page you want to track. ```html ``` 2. **Set your API key and load the page** Replace the placeholder with your project's API key, then load a tracked page in your browser. 3. **Confirm data in Amplitude** Open the [Amplitude Debugger](https://amplitude.com/docs/analytics/debug-analytics) and check for page view, session, and interaction events. **Tips** - Click the **API key** button in the code block to insert your key before you copy the snippet. - Use the EU CDN host if your project uses EU data residency. - Create a [free Amplitude account](https://app.amplitude.com/signup) if you need a project and API key. #### npm ### Install the Browser SDK with npm 1. **Install the Browser Unified SDK** Run this command in your project directory: ```bash npm install @amplitude/unified ``` 2. **Initialize Amplitude at app load** Import and call `initAll` once when your app starts: ```javascript import { initAll } from "@amplitude/unified"; initAll("AMPLITUDE_API_KEY"); ``` 3. **Track your first event** Call `track` anywhere in your app: ```javascript import { track } from "@amplitude/unified"; track("Button Clicked", { buttonId: "signup" }); ``` For full configuration options, see [Browser Unified SDK](https://amplitude.com/docs/sdks/analytics/browser/browser-unified-sdk). #### yarn ### Install the Browser SDK with yarn 1. **Install the Browser Unified SDK** Run this command in your project directory: ```bash yarn add @amplitude/unified ``` 2. **Initialize Amplitude at app load** Import and call `initAll` once when your app starts: ```javascript import { initAll } from "@amplitude/unified"; initAll("AMPLITUDE_API_KEY"); ``` 3. **Track your first event** Call `track` anywhere in your app: ```javascript import { track } from "@amplitude/unified"; track("Button Clicked", { buttonId: "signup" }); ``` For full configuration options, see [Browser Unified SDK](https://amplitude.com/docs/sdks/analytics/browser/browser-unified-sdk). #### AI Prompt ### Set up with an AI prompt Low-code setup with an AI assistant. Copy this prompt into an AI coding tool to set up the Amplitude Browser SDK for a JavaScript web app without running a full manual install. > **Tip:** Set up with an AI prompt > > Use this option when you want an AI tool to make the code changes for you. Full SDK setup for a JavaScript web app. [Autocapture](https://amplitude.com/docs/data/autocapture) and [Session Replay](https://amplitude.com/docs/session-replay). Remote config for feature flags and guides. 1. **Copy the prompt into your AI tool** Paste it into Cursor, Claude Code, Copilot, or another coding assistant that can edit your project. ```text Install and configure Amplitude for this JavaScript web application. Use API key: AMPLITUDE_API_KEY Requirements: - Run the implementation only on the client. - Initialize Amplitude once during app load. - Install the correct browser package for this project. - Enable fetchRemoteConfig: true. - Enable autocapture for attribution, page views, sessions, element interactions, form interactions, and file downloads. - Enable Session Replay with sampleRate: 1. - Preserve the project's existing TypeScript and framework patterns. ``` 2. **Review the generated changes** Confirm that the assistant installed the SDK, initialized it in the right client entry point, and kept the code client-side. 3. **Verify that events arrive** After the changes land, open the [Amplitude Debugger](https://amplitude.com/docs/analytics/debug-analytics) and confirm that page views and session data reach your project. **Tips** - Click the **API key** button in the code block to insert your key before you copy the prompt. - Create a [free Amplitude account](https://app.amplitude.com/signup) if you still need a project and API key. #### iOS ### Install the iOS SDK 1. **Add the SDK to your Xcode project** Choose Swift Package Manager or CocoaPods. **Swift Package Manager:** In Xcode, navigate to _File > Add Package Dependencies_ and enter: ```text https://github.com/amplitude/Amplitude-Swift ``` **CocoaPods:** Add to your `Podfile`, then run `pod install`: ```ruby pod 'AmplitudeSwift', '~> 1.0' ``` 2. **Initialize the SDK** Add this to your app delegate or `@main` entry point: ```swift import AmplitudeSwift let amplitude = Amplitude(configuration: Configuration( apiKey: "AMPLITUDE_API_KEY" )) ``` 3. **Track your first event** ```swift amplitude.track(eventType: "Button Clicked") ``` For full configuration options including Autocapture, see [iOS Swift SDK](https://amplitude.com/docs/sdks/analytics/ios/ios-swift-sdk). #### Android ### Install the Android SDK 1. **Add the SDK dependency** Add this to your `build.gradle`: ```gradle dependencies { implementation 'com.amplitude:analytics-android:1.+' } ``` 2. **Initialize the SDK** Add this to your `Application` class or main `Activity`: ```kotlin import com.amplitude.android.Amplitude val amplitude = Amplitude(AMPLITUDE_API_KEY, applicationContext) ``` 3. **Track your first event** ```kotlin amplitude.track("Button Clicked") ``` For full configuration options including Autocapture, see [Android Kotlin SDK](https://amplitude.com/docs/sdks/analytics/android/android-kotlin-sdk). #### Node.js ### Install the Node.js SDK 1. **Install the SDK** ```bash npm install @amplitude/analytics-node ``` 2. **Initialize Amplitude at startup** ```javascript import { init, track } from "@amplitude/analytics-node"; init("AMPLITUDE_API_KEY"); ``` 3. **Track your first event** ```javascript track("Button Clicked", undefined, { user_id: "user@example.com" }); ``` For full configuration options, see [Node.js SDK](https://amplitude.com/docs/sdks/analytics/node/node-js-sdk). #### React Native ### Install the React Native SDK 1. **Install the SDK and its dependency** ```bash npm install @amplitude/analytics-react-native npm install @react-native-async-storage/async-storage ``` 2. **Initialize Amplitude at app load** ```javascript import { init, track } from "@amplitude/analytics-react-native"; init("AMPLITUDE_API_KEY"); ``` 3. **Track your first event** ```javascript track("Button Clicked"); ``` For full configuration options, see [React Native SDK](https://amplitude.com/docs/sdks/analytics/react-native/react-native-sdk). #### Python ### Install the Python SDK 1. **Install the SDK** ```bash pip install amplitude-analytics ``` 2. **Initialize the client** ```python from amplitude import Amplitude, BaseEvent amplitude = Amplitude("AMPLITUDE_API_KEY") ``` 3. **Track your first event** ```python amplitude.track(BaseEvent( event_type="Button Clicked", user_id="user@example.com" )) ``` For full configuration options, see [Python SDK](https://amplitude.com/docs/sdks/analytics/python/python-sdk). #### Flutter ### Install the Flutter SDK 1. **Add the SDK to your project** ```bash flutter pub add amplitude_flutter ``` 2. **Initialize the SDK in your app** ```dart import 'package:amplitude_flutter/amplitude.dart'; import 'package:amplitude_flutter/configuration.dart'; final Amplitude amplitude = Amplitude(Configuration( apiKey: 'AMPLITUDE_API_KEY', )); await amplitude.isBuilt; ``` 3. **Track your first event** ```dart amplitude.track(BaseEvent('Button Clicked')); ``` For full configuration options, see [Flutter SDK](https://amplitude.com/docs/sdks/analytics/flutter/flutter-sdk-4). #### HTTP ### Send events via HTTP Send events directly to the Amplitude HTTP API without an SDK. This works in any environment that can make HTTP requests. 1. **Send your first event** Make a POST request with your API key and event data: ```bash curl -X POST https://api2.amplitude.com/2/httpapi \ -H "Content-Type: application/json" \ -d '{ "api_key": "AMPLITUDE_API_KEY", "events": [{ "user_id": "user@example.com", "event_type": "Button Clicked" }] }' ``` For EU data residency, use `https://api.eu.amplitude.com/2/httpapi` instead. See the [HTTP API Quickstart](https://amplitude.com/docs/apis/analytics/http-api-quickstart) and [HTTP API Reference](https://amplitude.com/docs/apis/analytics/http-v2) for full request options and error handling. --- ## Take the next step After data starts flowing, use these guides to expand your implementation. ### [Amplitude MCP server](https://amplitude.com/docs/amplitude-ai/amplitude-mcp) Query your analytics data from Claude, Cursor, or any other MCP-compatible client without leaving your workflow. ### [Claude Code plugin](https://github.com/amplitude/mcp-marketplace/tree/main/plugins/amplitude) Install the Amplitude plugin for Claude Code to get built-in slash commands for charts, dashboards, and instrumentation work. ### [Custom events](https://amplitude.com/docs/sdks/analytics/browser/browser-sdk-2#track-an-event) Track the product events that matter to your business after Autocapture covers the basics. ### [User identification](https://amplitude.com/docs/sdks/analytics/browser/browser-sdk-2#custom-user-identifier) Connect anonymous activity to known users so you can analyze behavior across sessions and devices. ### [Group analytics](https://amplitude.com/docs/sdks/analytics/browser/browser-sdk-2#user-groups) Analyze behavior at the account, workspace, or team level with user groups. ### [Session Replay](https://amplitude.com/docs/session-replay) Watch real user sessions alongside event data to find friction, confusion, and drop-off points.
