Umami Blocked by Ad Blockers (uBlock Origin, Brave)

How to fix it

Try these in order — the most common fix is first.

1. 1. Rename the script and endpoint (self-hosted)

   Copy steps
   1. Set TRACKER_SCRIPT_NAME to a neutral name, e.g. TRACKER_SCRIPT_NAME=x.js
   2. Set COLLECT_API_ENDPOINT to a neutral path, e.g. COLLECT_API_ENDPOINT=/api/x
   3. Restart Umami and change your script tag to load https://your-umami/x.js
   4. Avoid words like umami, analytics or stats in the subdomain
   Did this fix it? Yes No

2. 2. Proxy through your own domain

   Copy steps
   1. Serve the tracker from your domain at a path like /stats.js that fetches the Umami script
   2. Forward a path on your domain to the collect endpoint (https://gateway.umami.is/api/send for Cloud), passing User-Agent and client IP
   3. Set data-host-url on the script tag to your own domain
   4. In Next.js you can do this with rewrites in next.config
   Did this fix it? Yes No

3. 3. Host the script file yourself (no server access)

   Copy steps
   1. Download https://cloud.umami.is/script.js
   2. Upload it to your site under a neutral filename
   3. Set data-host-url so data still reaches Umami
   4. Re-download it whenever Umami updates the tracker
   Did this fix it? Yes No

4. 4. Use a Cloudflare Worker proxy

   Copy steps
   1. Create a Worker on your domain that forwards the script and collect requests to your Umami host
   2. Route a neutral path on your site to the Worker
   3. Point the script src and data-host-url at that path
   Did this fix it? Yes No

Symptoms

Visitor counts are lower than server logs or other tools, the script shows as blocked in DevTools, or tracking works in one browser but not in Brave or with uBlock Origin.

Why it happens

• Filter rule blocking umami.is as a third-party domain
• Default script name script.js and endpoint /api/send are on blocklists
• Umami running on a subdomain like umami.example.com or analytics.example.com that matches keyword rules
• Some lists block anything that behaves like analytics, regardless of name
