3. diff'd w/ BLEK
| Component | OpenSearch Equivalent | Notes |
|---|---|---|
| Elasticsearch | OpenSearch | Core search and analytics engine. Functional overlap, but OpenSearch is a fork, not a drop-in replacement. |
| Kibana | OpenSearch Dashboards | Visualization and management. Feature parity still developing. |
| Logstash | No direct equivalent | OpenSearch can ingest data directly or via tools like Fluentd/Fluent Bit. |
| Beats | Partially covered by agents | OpenSearch offers some data shippers (agents), but not the breadth of Beats. Community-driven alternatives may exist. |
