Reviewer scorecard
“Open-source Segment alternative with warehouse-native architecture. Self-hosting means your data never leaves your infra.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“Why pay Segment when RudderStack does the same job with open source and better warehouse support?”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“Warehouse-native CDP is the right architecture. Data should live in your warehouse, not a vendor's platform.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
