Muon vs Umami

Umami is simple open-source web analytics. Muon is an Umami-compatible system that is faster, more product-oriented, and designed to detect what changed.

How does Muon compare to Umami?

Umami is a simple open-source web analytics tool. Muon starts from the same simplicity but adds a faster Rust backend, product analytics, browser health and a diagnostic layer.

Choose Umami for simple web analytics; choose Muon for an Umami-compatible system that is faster, product-oriented, self-hostable and built to detect what changed.

Summary

Same roots. Different ambition.

Both are open source and self-hostable, and Muon speaks Umami's tracking protocol. The difference is what happens after the data lands.

Choose Umami if…

You want lightweight, privacy-friendly web analytics with a clean dashboard and a small footprint, and simple pageview and event counts are all you need.

Choose Muon if…

You want an Umami-compatible system that is faster under load and adds product analytics, browser health and diagnoses of meaningful changes.

Benchmark note

Faster on the same endpoint, on the same database.

In an internal benchmark using the same Umami-compatible /api/send endpoint and identical PostgreSQL setup, Muon achieved higher throughput, lower p99 latency and much lower memory usage than Umami. Under load Muon becomes PostgreSQL-bound while Umami remains application-runtime-bound.

This is an internal benchmark — see the methodology before making production decisions. Results depend on your workload and hardware.

Migration

Move from Umami without re-instrumenting.

Muon accepts Umami-compatible tracking payloads and provides migration tooling for existing Umami installations. Point an existing Umami tracker at Muon's /api/send endpoint, then run the importer for historical data.

Swap the tracker src

<!-- point your existing tracker at Muon -->
<script defer
  src="https://muon.example.com/script.js"
  data-website-id="your-umami-website-id">
</script>

Import existing Umami data

# run the Umami importer
docker compose up importer

# events now flow to Muon's /api/send
