Reviewer scorecard
“If you need billion-scale vector search, Milvus handles it. GPU indexing and distributed architecture set it apart.”
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Massive complexity for most use cases. Unless you're operating at true scale, simpler alternatives are better.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Purpose-built for the scale that enterprise AI will demand. The CNCF backing adds credibility.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
