Install

curl -fsSL https://fusionaly.com/install | bash

Or with Docker:

docker pull karloscodes/fusionaly:latest

See the Installation Guide for full setup instructions.

How It Works

Add the tracking script to your site:

<script defer src="https://your-domain.com/y/api/v1/sdk.js"></script>

Page views and button clicks are tracked automatically. Want more? One attribute works on any element:

<button data-fusionaly-event-name="signup_clicked">Sign Up</button>
<a href="/pricing" data-fusionaly-event-name="pricing_viewed">Pricing</a>
<form data-fusionaly-event-name="contact_submitted">...</form>
<section data-fusionaly-event-name="testimonials_seen">...</section>

The SDK does the right thing based on element type — click, submit, sendBeacon, or scroll into view. Read the docs.

Features

• Page views & SPA navigation — automatic, zero config
• Button & link tracking — automatic or named with one attribute
• Form tracking — tracks on submit, suppresses button double-events
• Section tracking — fires when scrolled into view (50% visible)
• Revenue tracking — purchases with price, currency, metadata
• Custom events — JavaScript API for dynamic data
• Goal conversions — track signups, purchases, any event as a goal
• User flows — see how visitors navigate entry to exit
• Annotations — mark deployments, campaigns, incidents on your timeline
• Shareable dashboards — public links to your analytics
• Bot filtering & spam protection — clean data by default
• Subdomain tracking — first-party, ad-block proof
