The honest brief
MyScale
Built as a ClickHouse fork, so one SQL query can mix vector search, full-text search, and analytics—no separate vector store to keep in sync.
- Open source (Apache-2.0), self-hostable
- SQL joins vectors with structured data
- Built on battle-tested ClickHouse
- Free managed starter pod
- Smaller community than Pinecone/Milvus
- Open-source release cadence slowed after 2024
- SQL-first model has a learning curve
Weaviate
Built-in vectorizer modules embed text inline — raw text in, vectors out — so you skip running a separate embedding pipeline.
- Hybrid BM25 + vector search
- Self-hostable or managed cloud
- GraphQL and REST APIs
- Resource-heavy at large scale
- Module config has a learning curve
- Managed tier costs add up
- Newer than some lexical engines
