The short version

  • Each has a real cost: Privacy Badger it is not an ad blocker; the project states its aim is to prevent non-consensual tracking rather than to block ads; Umami there is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • They diverge on capability: Privacy Badger covers Automatic tracker detection, Umami covers Cookie-free tracking.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Privacy Badger

  • It is not an ad blocker; the project states its aim is to prevent non-consensual tracking rather than to block ads
  • There is no Safari build, and Safari on iOS lacks extension capabilities Privacy Badger needs to work
  • Chrome on Android does not support extensions, so Android users have to switch to Firefox or Edge
  • Protection is aimed at third-party trackers and does not comprehensively cover tracking by the site you are actually visiting

Umami

  • There is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • Self-hosting is only free in licence terms; you own the database, the upgrades, the backups and the query performance at scale, and a busy site's events table grows quickly enough to need real attention.
  • Because it stores no persistent identifier, it cannot follow a user across devices or sessions in any meaningful way, which makes returning-visitor and lifetime-value questions unanswerable by design rather than by omission.
  • Cloud overage is billed per event beyond the plan allowance, so a traffic spike or a badly instrumented custom event can produce a bill materially above the $20 or $200 headline before anyone notices.
  • It is maintained by a small team, so the pace of new capability is modest and enterprise expectations such as SSO, granular role permissions and formal support agreements are limited compared with commercial analytics vendors.
