Add the snippet

Register a site in Settings, then drop one script on it. Pageviews — including single-page navigations — are tracked automatically.

Script tag

Paste this in your site's <head>, with your own site ID:

<script
    id="ptmetrics-script"
    data-site-id="your-site-id"
    src="https://your-server/tracker.js"
    defer
></script>

Or npm

For browser-based projects that prefer modules:

npm install @ptmetrics/tracker

import * as Tarsier from "@ptmetrics/tracker";

Tarsier.init({
    siteId: "your-site-id",
    reporterUrl: "https://your-server/collect",
});

One script, sixty seconds, zero cookies. Then open your dashboard and watch the first visitor arrive. Probably you.

Watched by Tarsier

A little bubble with his eyes, linking back here. Paste it anywhere you want the credit:

<script src="https://your-server/badge.js" defer></script>

Single-page apps

Client-side navigations are tracked automatically — no router hooks, no manual calls. If you render pages yourself instead, set autoTrackPageviews: false and call Tarsier.trackPageview() when a pageview happens.
