@glossia/web

Cookieless, privacy-friendly web analytics that surfaces localization opportunities. Add one line of HTML and Glossia shows you which languages and countries your visitors actually want, and where you have a localization gap.

• No cookies, no fingerprinting. Nothing is stored on the visitor's device. Unique visitors are derived server-side from a daily-rotated hash that cannot be linked across days.
• Localization-first. Collects browser languages, country (GeoIP), referrer, and the pages underserved traffic lands on, so you can prioritize the next locale with data.
• Tiny. One small script, no dependencies, ships via sendBeacon.

Install

Snippet (no build step)

Add this to your site:

<script defer data-domain="example.com" src="https://cdn.glossia.ai/web.js"></script>

The script auto-initializes and records pageviews, including on client-side navigation (single-page apps). data-domain is optional — when omitted, the SDK uses window.location.hostname to identify the project. Point data-endpoint at a self-hosted collect host if you don't use the Glossia CDN.

npm

npm install @glossia/web

import glossia from "@glossia/web";

glossia.init();

// Record a custom event:
glossia.track("signup");

domain is inferred from window.location.hostname. Pass { domain: "example.com" } to override, for example to send events from a staging origin to the same project as production.

What gets collected

Sent from the browser: page URL, referrer, navigator.languages, timezone, screen width, and a per-tab session id (in sessionStorage, cleared on close).

Derived on the server (never stored raw): a daily-rotated visitor id, country from GeoIP, device/browser/OS from the User-Agent, and the localization gap against your project's target languages.
