Show HN: Otel-GUI – an open source OpenTelemetry viewer for dev and debug

(The author is a work colleague, I'm posting on his behalf due to "Show HN" limitations for new accounts)

During my recent projects with OpenTelemetry, I was looking for a truly practical tool for local development.

I found several existing solutions —some very powerful— but for my day-to-day local use, they were often too heavy, not simple enough to install, or not quick enough to get started with.

So I decided to build my own dedicated tool: otel-gui.

This is not a complete observability suite nor a telemetry backend designed for large-scale production or long-term retention. It's a tool designed for developers who want to debug efficiently locally.
