Counterscale

Counterscale is a simple web analytics tracker and dashboard that you self-host on Cloudflare.

It's designed to be easy to deploy and maintain, and should cost you near-zero to operate – even at high levels of traffic (Cloudflare's free tier could hypothetically support up to 100k hits/day).

NOTE: Counterscale is currently in very early development and shouldn't be used in any actual production setting. We welcome people trying it and giving feedback/contributing, but heads up this project is still super early.

Deployment

If you don't have one already, create a Cloudflare account here.

1. Go to your Cloudflare dashboard and set up a Cloudflare Workers subdomain
2. Enable Cloudflare Analytics Engine beta for your account (screenshot)
3. Create a Cloudflare API token. This token needs Account.Account Analytics permissions at a minimum.
4. Run npm install
5. Run npx wrangler secret put CF_BEARER_TOKEN → when prompted, paste the API token you created
6. Run npx wrangler secret put CF_ACCOUNT_ID → when prompted, paste your Cloudflare Account ID
7. Run npm run deploy – this will do two things:
   1. Create a new worker, counterscale, now visible under Workers and Pages in Cloudflare
   2. Create a new Analytics Engine dataset, called metricsDataset
8. It should now be live. Visit https://counterscale.{yoursubdomain}.workers.dev.

Troubleshooting

If the website is not immediately available (e.g. "Secure Connection Failed"), it could be because Cloudflare has not yet activated your subdomain (yoursubdomain.workers.dev). This process can take a minute; you can check in on the progress by visiting the newly created worker in your Cloudflare dashboard (Workers & Pages → counterscale).

Custom Domains

The deployment URL can always be changed to go behind a custom domain you own. More here.

Installing the Tracker

When Counterscale is deployed, it makes tracker.js available at the URL you deployed to:

https://counterscale.{yoursubdomain}.workers.dev/tracker.js

To start tracking website traffic on your web property, copy/paste the following snippet into your website HTML:

<script>
    (function () {
        window.counterscale = {
            q: [["set", "siteId", "your-unique-site-id"], ["trackPageview"]],
        };
    })();
</script>
<script
    id="counterscale-script"
    src="https://counterscale.{yoursubdomain}.workers.dev/tracker.js"
    defer
></script>

Be sure to replace your-unique-site-id with a unique string/slug representing your web property. Use a unique site ID for each property you place the tracking script on.

Development

Config

To get started, in the project root, copy .dev.vars.example to .dev.vars.

Open .dev.vars and enter the same values for CF_BEARER_TOKEN and CF_ACCOUNT_ID you used earlier.

Running the Server

Counterscale is built on Remix and Cloudflare Workers. In development, you'll run two servers:

• The Remix development server
• The Miniflare server (local environment for Cloudflare Workers)

You run both using:

npm run dev

Afterwards, the dashboard should be visible at http://127.0.0.1:8787.

If you want to check the production build, you can stop the dev server and run following commands:

npm run build
npm start

Then refresh the same URL in your browser (no live reload for production builds).

Notes

Database

There is only one "database": the Cloudflare Analytics Engine dataset, which is communicated entirely over HTTP using Cloudflare's API.

Right now there is no local "test" database. This means in local development:

• Writes will no-op (no hits will be recorded)
• Reads will be read from the production Analaytics Engine dataset (local development shows production data)

Sampling

Cloudflare Analytics Engine uses sampling to make high volume data ingestion/querying affordable at scale (this is similar to most other analytics tools, see Google Analytics on Sampling). You can find out more how sampling works with CF AE here.

Contributing

Counterscale development is 100% volunteer-driven. If you use and like this software and want to see it improve, we encourage you to contribute with Issues or Pull Requests.

Development Philosophy

The primary goal of Counterscale is to be super easy to self-host and maintain. It should be "set up once and forget".

To achieve that:

• There should be no application state outside of CF Analytics Engine
  • e.g. no additional relational database like MySQL, PostgreSQL, etc.
  • That means no users table, no sites table, etc.
  • This also means retention will be limited by what CF Analytics Engine provides. While it could be possible to stand up a "hit counter" for long-lived data (e.g. years), that would mean another database, which we will not pursue.
• We prioritize backwards compatibility
  • New metricsDataset columns can be added, but old columns cannot be removed or renamed (they can however, be "forgotten").
  • That also means it's okay if a feature only works during a period where the data is active.
