No Cookies

Zero cookies means zero consent banners. Uses localStorage with anonymous IDs that can't track users across sites.

GDPR Compliant

No personal data collected. No IP addresses stored. No browser fingerprinting. Privacy by design.

Lightweight

Under 3KB gzipped. Loads async. Never blocks rendering. Won't slow down your site.

Real-Time Data

Events appear in your dashboard immediately. No sampling, no delays, no data limits.

SPA Support

Automatically tracks client-side navigation. Works with React, Vue, Next.js, and any SPA framework.

Error Tracking

Captures JavaScript errors and unhandled promise rejections automatically. See what's breaking.

How It Works

1

Create a CTag

Sign up, create an organization, and generate a tracking key with your allowed domains.

2

Add the Script

Drop a single script tag in your HTML. One line. No build step. No SDK.

3

View Your Data

Pageviews, custom events, and errors appear in real-time. Filter by domain, path, session, or user.

One Script Tag

<script
  src="https://d1gcl24ubvdlg4.cloudfront.net/ctag.js"
  data-key="C-YOUR_API_KEY"
  async
></script>
