// EDITOR'S TAKE
OpenObserve is the closest to Splunk's core loop of ingesting everything and searching it later, with HyperDX a friendlier front end over the same columnar approach for application logs and traces. Grafana is a visualisation layer rather than a log store, so it only replaces Splunk once you pair it with a backend, and Logstash solves ingest alone.
