CustomerOS

CustomerOS Website Tracker

Client-side JavaScript tracker that captures page views and custom events, exposes window.cos.identify() for attaching identity and properties, and matches visitor IPs to companies. Since the 2025-09-08 change CustomerOS supports it ONLY when served from a reverse proxy on the customer's own domain, so the base URL is templated by design — there is no CustomerOS-hosted CDN URL to record and no version-pinned build.
