Why do I self-host tracker? I am uncomfortable allowing any third-party (including trusted ones such as Fathom) into my JavaScript environments which could be used as a backdoor.

This projects solves two problems…

First, code is deobfuscated so one can audit how it works.

Second, it adds a data-domain attribute so one can set custom domain which, in reference implementation, is set to hostname of script.

<script
  src="script.min.js"
  data-domain="twenty-graceful.sunknudsen.com"
  data-site="JNIACVCL"
  …
></script>
