Pros & Cons

OpenSearch logo
OpenSearch

Pros

  • The Apache 2.0 licence and Linux Foundation governance remove vendor licence fees and lock-in.
  • Security features such as RBAC, audit logging, SAML and OIDC are free, whereas Elastic puts some of these behind paid licences.
  • AI features are moving quickly: agentic search went GA in 3.3, and agent memory, MCP support and LLM-as-judge relevance testing came in later 3.x releases.
  • It runs on Kubernetes, Docker, bare metal or the managed Amazon OpenSearch Service, using the same codebase.

Cons

  • Large or multi-tenant clusters often need manual tuning of caches, merges and thread pools.
  • Dashboards is a Kibana 7.10 fork and is described as less polished than current Kibana.
  • Plugin features such as k-NN and anomaly detection can vary in stability between versions.
  • Some benchmarks and Elasticsearch users report performance and feature gaps against current Elasticsearch.

Portkey

Pros

  • Unified API covering more than 1,600 models, with automatic fallbacks, retries, and load balancing.
  • Detailed logs and traces show the latency, cost, and retry path of each request.
  • An open-source core and a free tier let developers try it before paying.
  • Enterprise governance features include budgets, rate limits, RBAC, SSO, and audit logs, with VPC deployment available.

Cons

  • Since the 2026 acquisition, paid plans route through Palo Alto Networks' Prisma AIRS, which brings uncertainty about future pricing and roadmap.
  • You pay for the gateway on top of LLM provider costs, and provider billing stays separate.
  • Below Enterprise, support is community-only, and the free plan keeps logs for just 3 days.
  • It may be more platform than needed for small prototypes that want only a simple proxy.
