A standalone port of GoatCounter to run entirely on Cloudflare's edge infrastructure.

CloudCounter brings GoatCounter's privacy-focused analytics to Cloudflare Pages + D1, requiring no external servers or databases. Deploy once and track pageviews across your sites with a single JavaScript snippet.

Features

• Pageview tracking with session deduplication
• Top pages, referrers, browsers, operating systems, locations
• Screen size breakdown
• Event tracking support
• Privacy-first: no cookies, session hash only
• Server-rendered dashboard
• Data retention policies

Screenshots

Prerequisites

• Node.js 18+
• Wrangler CLI
• Cloudflare account with Pages and D1 access

Quick Start

1. Clone and install

git clone https://github.com/philippdubach/cloudcounter.git
cd cloudcounter
npm install

2. Create Cloudflare resources

# Create D1 database
wrangler d1 create cloudcounter

# Create KV namespace for sessions
wrangler kv namespace create SESSIONS

3. Update wrangler.toml

Edit wrangler.toml and add your database_id and KV namespace id:

[[d1_databases]]
binding = "DB"
database_name = "cloudcounter"
database_id = "YOUR_DATABASE_ID_HERE"

[[kv_namespaces]]
binding = "SESSIONS"
id = "YOUR_KV_NAMESPACE_ID_HERE"

4. Initialize database

wrangler d1 execute cloudcounter --file=./migrations/0001_init.sql

5. Set dashboard password

wrangler secret put DASHBOARD_PASSWORD

6. Deploy

wrangler pages deploy public

7. Add tracking script to your site

<script async src="https://your-analytics.pages.dev/count.js"></script>

Local Development

# Start local dev server
npm run dev

# Apply migrations to local D1
npm run db:migrate:local

Tracking Script

Basic usage

The script auto-tracks pageviews on load:

Manual tracking

// Custom pageview
cloudcounter.count({ path: '/custom-path', title: 'Custom Title' });

// Event tracking
cloudcounter.count({ path: 'button-click', title: 'Sign Up Button', event: true });

Click tracking

Add data-cloudcounter-click attribute to elements:

<button data-cloudcounter-click="signup-btn">Sign Up</button>

Disable tracking

cloudcounter.skip();   // Disable for this session
cloudcounter.enable(); // Re-enable
