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

Pendo

Pricing is not publicly available and requires a custom quote
Free tier limited to 500 monthly active users
