Choose cognee if…
- Tags unique to cognee: vector-database, python, docker, rust.
- Also covers AI Agents.
- cognee ships Docker support for self-hosted deployment.
- - You are developing AI agents that require persistent long-term memory across different sessions.
When NOT to use cognee
- - Your project does not require persistent memory storage, or your agents operate fully within short-lived sessions without the need for past context.
- - You are aiming for minimal setup overhead and prefer a cloud-based solution that requires less maintenance on your infrastructure side.
Choose vectorai if…
- Tags unique to vectorai: neural-networks, clustering, embeddings, deep-learning.
- Also covers Model Training.
- Leaner open-issue backlog (12).
When NOT to use vectorai
- Last GitHub push was 863 days ago (dormant maintenance, Mar 1, 2024). Validate activity before betting a new project on vectorai.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
