Umami: Solving Geolocation (City and Region) with Cloudflare Tunnels

Tue, 17 Mar 2026 19:00:00 -0700

Umami is one of the best privacy-focused, self-hosted alternatives for web analytics. However, an extremely common issue when deploying it behind Cloudflare Tunnels is that the dashboard identifies the visitor’s country, but the City and Region fields appear empty (—).

In this guide, we will look at how to fix this telemetry “short circuit” by correctly configuring HTTP headers so that Cloudflare provides Umami with all the geographic information it needs.

Umami: Deploying Umami Analytics with Docker

Sun, 15 Mar 2026 01:35:00 -0700

Maintaining absolute control over your visitors’ demographic and behavioral data is essential in the world of Enterprise technology. Umami Analytics has become the leading alternative for those seeking a lightweight, privacy-friendly, and, above all, easy-to-deploy solution through Docker.

Why Self-Hosted over the Cloud version?

While Umami offers a cloud version, self-hosting provides undeniable advantages for technical or corporate profiles:

No retention limits: The cloud’s free version often has limits on how many events you can process or how long they are stored. On your own server, the only limit is your storage.
Data Sovereignty: Data never leaves your infrastructure. This is vital for privacy compliance or simply for total control.
Privacy by Design: By not relying on third-party servers, you eliminate an external tracking point.
Zero Operational Cost: If you already have a server with Docker, adding an Umami container doesn’t increase your monthly costs.

1. Environment Preparation

Umami requires a database to store metrics. The cleanest and most self-contained way to deploy it is by using Docker Compose to spin up both the Umami application and a PostgreSQL database in the same stack.

Docker: Automatic Image and Log Cleanup

Wed, 04 Mar 2026 21:15:00 -0800

Why doesn’t Docker automatically clean up junk files?

If you’ve had a Docker server for more than a month, you’ve probably noticed that disk space mysteriously disappears. Docker is designed on the principles of immutability and security. It doesn’t delete anything by default because it can’t guess whether that “orphaned” image from three months ago is a critical version you plan to roll back to, or if that build cache is something you need for a quick deployment tomorrow.
