Sorry for bringing up my own side-project on a "Show HN", but I'm making humanlog.io which does exactly what you want. Local-first log query engine (and tracing too, soon). You feed it your logs and you can search them, aggregate them, and soon make some graphs and dashboards with them. It started as just a CLI tool to parse and make structured logs pretty, and now I'm turning it into a full observability tool on your machine.

It's very WIP but I would love to help you get started if you want to try it out.
