The short version

  • Each has a real cost: ChartMogul the free tier stops at $10K MRR, so it lapses precisely as a company starts to matter; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: ChartMogul covers MRR Analytics, OpenSearch covers Full-text search.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

ChartMogul

  • The free tier stops at $10K MRR, so it lapses precisely as a company starts to matter
  • Starter is capped at 3 team members and a single billing system connection
  • Two-way CRM sync and warehouse integration require the Pro tier
  • Pricing scales with your ARR rather than with usage, so the bill rises as the business grows
  • Enterprise starts at $19,900 a year and is required above $10M ARR

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
