The short version

  • Each has a real cost: OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one; Traceloop free tier limited to 50k spans per month and 24-hour retention, restricting production use
  • They diverge on capability: OpenSearch covers Full-text search, Traceloop covers Open-source SDK (OpenLLMetry).
  • Prices and features above were last checked on 29 August 2026.

OpenSearch

  • Log and observability storage where an Apache-2.0 licence is a requirementnot Traceloop

  • Search plus analytics on one cluster rather than two systemsnot Traceloop

Traceloop

  • Monitoring LLM application performance in productionnot OpenSearch

  • Continuous evaluation and quality scoring of LLM outputsnot OpenSearch

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

Traceloop

  • Free tier limited to 50k spans per month and 24-hour retention, restricting production use
  • Company acquisition by ServiceNow creates uncertainty about future roadmap
  • Requires integration with separate observability platforms for visualization
  • Less feature-rich than dedicated LLM evaluation platforms
