Reviewer scorecard
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“JSON documents, full-text search, and vector similarity in Redis. One less database to manage.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Redis doing more than caching makes sense. The module consolidation reduces infrastructure complexity.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
“Redis evolving from cache to multi-model database positions it for more use cases without added infrastructure.”
