Has anyone given OpenObserve a try?

If your team has solid engineering skills, you might want to consider the LGTM stack instead. I haven't heard much about OpenObserve; their offer doesn't seem particularly exciting, and some of their claims feel a bit sketchy. It's always good to verify things on your own!

Yes, I run OpenObserve at a decent scale and have also worked with the Grafana stack. OpenObserve is definitely easier to scale, and they have clear documentation on that. Plus, it's a lot cheaper than Loki for complex searches. The team is very responsive on Slack, unlike Grafana. However, I do feel the UI needs improvement—it tries to mimic Kibana but can be tricky to navigate initially.

We’re exploring similar options, so take this with a grain of salt, but have you checked out Parseable? It's open-source and designed for teams looking for a unified solution for logs, traces, and events, all in one place with a clean UI. Plus, it uses S3-compatible storage to avoid scaling headaches. Just thought I'd throw that out there!

I've tested OpenObserve locally while working on some open observability projects. It’s user-friendly and pretty intuitive, but I found the UI to be a bit lacking during my small tests.
