Inspectlet JavaScript SDKs

Official Inspectlet packages for modern JavaScript apps — session recording, heatmaps, form analytics, and AI session insights in a few lines of code.

A modern alternative to LogRocket, FullStory, and Hotjar — with Inspectlet's deep form analytics, AI session insights, and a free tier that's free forever.

Package	Description
@inspectlet/browser	Typed wrapper around the Inspectlet tracker. Works in any browser app.
@inspectlet/react	React provider, hooks, and automatic pageview tracking for Next.js / React Router.

Quickstart (React / Next.js)

npm install @inspectlet/browser @inspectlet/react

import { InspectletProvider } from '@inspectlet/react';

export default function App({ children }) {
  return (
    <InspectletProvider config={{ wid: 'YOUR_WID' }}>
      {children}
    </InspectletProvider>
  );
}

For automatic SPA pageview tracking, also import the adapter for your router:

import { useNextPageviews } from '@inspectlet/react/next';        // Next.js App Router
import { useReactRouterPageviews } from '@inspectlet/react/router'; // React Router v6+

Quickstart (vanilla JS / TS)

npm install @inspectlet/browser

import { init, inspectlet } from '@inspectlet/browser';

init({ wid: 'YOUR_WID' });

inspectlet.identify('user_123');
inspectlet.tagSession({ plan: 'pro' });

Why these packages?

• No tracker bundling. The tracker JS still loads from cdn.inspectlet.com, so bug fixes and new features reach your users immediately — you don't need to redeploy your app to get tracker improvements.
• TypeScript-first. Every command is typed.
• SSR-safe. All methods are silent no-ops on the server. Works in Next.js, Remix, Nuxt, Astro, etc.
• Tiny. ~1.5 KB gzipped, zero dependencies, tree-shakeable.
