How to add analytics to your Vite, React or Vue site

This adds measuremy.site, cookieless website analytics, to a Vite, React or Vue site. It is one script tag of under 1 KB: no cookies, no npm package, no consent banner for the tracker. The free plan covers 5,000 pageviews a month.

The quickest way: ask your coding agent

Paste this into Claude Code, Cursor or Codex
Add measuremy.site analytics to this project: connect the measuremy.site MCP server at https://a.measuremy.site/mcp (it signs in with OAuth, no key), then tell me how to sign in. Details: measuremy.site/llms.txt

The agent connects to measuremy.site, you sign in through your browser, and it adds the tag below to the right file for you. To do it by hand, follow the steps.

1. Get your site key

Create a free account and add your domain. The Setup tab shows your snippet with your site key filled in. The key is public and can only record visits, so it is safe in your source code.

2. Add the script tag

Single-page apps built with Vite (React, Vue, Svelte, Solid, Preact) have one index.html at the project root. Add the tag inside its <head>:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>My app</title>
    <script defer src="https://a.measuremy.site/t.js" data-key="YOUR_SITE_KEY"></script>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/src/main.tsx"></script>
  </body>
</html>

Route changes made by React Router, TanStack Router, Vue Router and other History API routers are counted as pageviews automatically. Hash-based routing (#/page) is not.

3. Check it works

Publish the change, then open your live site. The first visit from your own domain verifies it and the visit shows up on the dashboard within seconds. Visits from localhost aren't counted, so test on the deployed site.

4. Track signups and other conversions

Call it from a component after the action succeeds:

async function handleSignup(form: FormData) {
  await createAccount(form);
  window.measuremysite?.track("signup");
}

In TypeScript, declare measuremysite?: { track(name: string, props?: Record<string, unknown>): void } on Window in a .d.ts file.

Or, with no JavaScript, add data-measuremysite-event="signup_click" to any link, button or form.

Any event counts as a conversion for the channel the visitor came from.

Other platforms, and funnels and campaign links, are in the install guide.

Try it on your site

Free for 5,000 pageviews a month, no card. Paste one sentence into your coding agent, or add one script tag yourself.
