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
