When NOT to use weaviate
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- If your project strictly requires a proprietary solution, Weaviate, being open-source under the BSD 3-Clause License, may not be the best fit.
- If your application does not require vector search or structured filtering, Weaviate's specialized capabilities might be overkill.
- For teams that prefer a different programming language, Weaviate is primarily developed in Go, which might not align with all development environments.
