The Elastic Stack: Free. Open. Limitless.
From the very beginning, the Elastic Stack — Elasticsearch, Kibana, Beats, and Logstash — has been free and open. Our approach is not only to make our technology stack available for free, but to make it open — housed in public repositories and developed through a transparent approach with direct involvement from the community. Two simple principles — free and open — broke down barriers and enabled many amazing things.
