I took a look at their documentation and their rule catalog files.
Rule Catalogs - ClearURLs
To briefly compare and contrast between the methodologies:
- I use an allowlist, whereas they use a blocklist with exceptions.
- My rules are for services outside of Big Tech, whereas their rules are designed for users who directly continue to use Big Tech services (Amazon, Bing, Facebook, Google, Reddit, X, etc).
- My eBay allowlist is well defined and fairly comprehensive for guest checkout, whereas their eBay blocklist only blocks 4 URL parameters.
"ebay": {
"urlPattern": "^https?:\\/\\/(?:[a-z0-9-]+\\.)*?ebay(?:\\.[a-z]{2,}){1,}",
"rules": [
"_trkparms",
"_trksid",
"_from",
"hash"
],
"redirections": [
"^https?:\\/\\/(?:[a-z0-9-]+\\.)*?rover\\.ebay(?:\\.[a-z]{2,}){1,}\\/rover.*mpre=([^&]*)"
]
},
- My wildcard filter rules have no exceptions, but their global filter rules allow tracking exceptions:
"exceptions": [
"^https?:\\/\\/(?:[a-z0-9-]+\\.)*?matrix\\.org\\/_matrix\\/",
"^https?:\\/\\/(?:[a-z0-9-]+\\.)*?(?:cloudflare\\.com|prismic\\.io|tangerine\\.ca|gitlab\\.com)",
