Reviewer scorecard
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
