The short version

  • Each has a real cost: Hotjar website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: Hotjar covers Heatmaps, 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.

Hotjar

  • Website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings
  • Session recording limits - free and lower-tier plans have monthly session recording caps that must be sampled above the limit
  • Inaccurate heatmaps on dynamic pages - heatmaps fail to display correctly on pages with modals, sticky navigation bars, and pop-up overlays
  • No mobile app - only web-based access available
  • Not real-time analytics - includes slight data processing delay

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

Yes, Apache 2.0 licensed under the Linux Foundation. Amazon OpenSearch Service is a paid managed option.

OpenSearch: Why does OpenSearch exist?

Elastic moved Elasticsearch off the Apache 2.0 licence in 2021. AWS forked the last Apache-licensed version, and the project now sits under the Linux Foundation.

Hotjar: Does Hotjar provide real-time analytics?

No. Hotjar has a slight delay in data processing and does not offer true real-time analytics compared to some competitors.

Source
OpenSearch: Is OpenSearch compatible with Elasticsearch?

It was at the 7.10 fork point. Both have developed independently since, so compatibility weakens with every release and should be verified for the features you use.

Hotjar: What integrations does Hotjar support?

Hotjar integrates with Google Analytics, Google Tag Manager, Slack, HubSpot, Jira, Linear, Microsoft Teams, Zapier, and hundreds of other tools through its API and partner integrations.
