When NOT to use vectordb
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- Last GitHub push was 224 days ago (slowing maintenance, Nov 29, 2025). Validate activity before betting a new project on vectordb.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.

Head-to-head comparisons
Common questions
- What are the best alternatives to vectordb?
- Graph-backed alternatives to vectordb include llm-app, vearch, bootcamp, cherche, databend. GraphCanon ranks them by typed relationship edges and constraint overlap from decision_facts - not marketing votes or raw star sort.
- How does GraphCanon rank vectordb alternatives?
- Direct alternative and successor edges from the knowledge graph come first, ordered by edge type and shared constraint facets (persona, runtime, hosting). Category neighbours fill the list only after curated edges. Stars are shown for context, not as the primary sort.
