## What you get with atrby

Only what it does today.

- **Revenue by source.** Stripe, Lemon Squeezy, Polar, Paddle, Dodo and Shopify by signed webhook. Each payment is matched to the visit that brought it.
- **Cookieless by default.** No cookie banner needed in the default mode. Visitor ids come from a salt that changes daily and is deleted.
- **AI traffic.** Visits and revenue from ChatGPT, Perplexity, Claude and Gemini, plus which AI crawlers read your pages.
- **Funnels and goals.** Ordered funnels per visit and goals on pages or events, with the revenue of visitors who converted.
- **Web vitals from real visits.** LCP, INP, CLS, FCP and TTFB measured by the same script. No extra tag.
- **Priced on pageviews only.** From $19 a month. Events, goals, revenue and crawler hits are never metered.
- **Never locked out.** Over your tier we keep collecting and the dashboard stays open. A 14-day trial needs no card.
- **Alerts and a weekly digest.** Revenue drops, traffic spikes and a broken install by email. A Monday summary of what changed.

## Run both side by side

Keep whichever tells you more.

### 01. Add atrby next to GA4

One script tag in the head. It doesn’t touch GA4, and both can run together.

```html
<script defer src="https://atrby.site/atrby.js" data-site="…"></script>
```

### 02. Connect your payments

One click for each processor. atrby pulls 90 days of payments on connect, so revenue by source fills in on day one.

### 03. Compare for 14 days

Look at both side by side. Remove GA4 only when the numbers line up, or keep both.
