Have you looked at https://signoz.io/ ? Its the closest I have tried, but I still wouldn't put it quite at the same level of usability.

Doesn't seem like this can visualize over data stored in Honeycomb like Grafana can :(

		It’s a full fledged tool like DataDog which is opensource and can be selfhosted. You can replace honeycomb with it. What features do you think it’s missing compared to honeycomb?
