The short version

  • Each has a real cost: Semgrep free tier caps out at 10 contributors and 10 repositories.; 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: Semgrep covers Static code scanning, Umami covers Cookie-free tracking.

  • A team that wants analytics data in a database they already control so they can query and join it themselvesnot Semgrep

Where each one falls short

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

Semgrep

  • Free tier caps out at 10 contributors and 10 repositories.
  • Secrets scanning is priced as a separate module ($15/contributor) from Code and Supply Chain.
  • Self-managed repositories and custom CI/CD require the Enterprise tier.
  • AI credits are limited per tier and additional usage requires upgrading.

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.
