Is OpenSearch worth the price?

How OpenSearch Compares to Competitors
Compared to Elastic Cloud, OpenSearch's open-source nature provides a significant cost advantage for self-hosting. While Elastic Cloud offers a free tier, its paid plans can quickly become more expensive than AWS Serverless for similar managed capabilities, especially for smaller workloads. OpenSearch's AWS integration also provides a more seamless experience for existing AWS users.
