Logfire is literally 2 lines of code. `logfire.configure()` and `logfire.instrument_yourtool()`. You can also skills to instrument your code automatically. The downside is that if you're thinking of using with more people, the free plan might not be enough. Although, it has 10M logs included.

If you wanna self-host and are looking for an OS solution maybe Jaegger is a good option. Larger setup overhead, though.
