Open Source Go Protocols

GoatCounter is an open-source web analytics platform available as a hosted service (free for non-commercial use) or self-hosted app. It aims to offer easy-to-use and meaningful privacy-friendly web analytics as an alternative to Google Analytics or Matomo. Privacy-aware; doesn’t track users with unique identifiers and doesn't need a GDPR notice. Fine-grained control over which data is collected. Also see the privacy policy and GDPR consent notices. Lightweight and fast; adds just ~3.5KB of extra data to your site. Also has JavaScript-free "tracking pixel" option, or you can use it from your application's middleware or import from logfiles. Keeps useful statistics such as browser information, location, and screen size. Keep track of referring sites and campaigns. Easy; if you've been confused by the myriad of options and flexibility of Google Analytics and Matomo that you don't need then GoatCounter will be a breath of fresh air.
