Weaviate - Pros & Cons
Pros
- ✓BSD-3 open-source licensing allows inspection, modification, and self-hosting without a database license fee.
- ✓Hybrid BM25 and vector retrieval handles both semantic questions and exact terms such as model numbers or SKUs.
- ✓Integrated vectorizers, rerankers, and generative modules can remove several services from a basic RAG stack.
- ✓Per-tenant isolation is a strong fit for B2B SaaS products with many customer knowledge bases.
- ✓Managed and self-hosted deployment paths reduce the need to replace the database as a project matures.
Cons
- ✗Self-hosting requires capacity planning, upgrades, backups, monitoring, and incident response.
- ✗HNSW indexes may consume substantial memory at large scale unless quantization and index settings are tuned.
- ✗Cloud storage-unit pricing is less intuitive than a fixed monthly plan and needs workload modeling.
- ✗The collection schema, GraphQL surface, modules, and index settings create a steeper learning curve than a minimal local vector store.
- ✗Using database-managed embedding and generation modules can increase coupling to Weaviate-specific configuration.
