## Choose when

### Choose caffe if…

- Tags unique to caffe: c++, deep-learning, machine-learning, vision.
- Also covers Computer Vision.
- More GitHub stars (35k vs 763) - visibility, not fit.

### Choose write-you-a-vector-db if…

- Tags unique to write-you-a-vector-db: bustub, database, tutorial, vector-database.
- When you aim to gain hands-on experience with implementing a vector database through an academic and instructive approach, utilizing the BusTub system from CMU-DB as the underlying technology.
- More recently updated (last pushed Jan 19, 2025).

## When NOT to use caffe

- Last GitHub push was 710 days ago (dormant maintenance, Jul 31, 2024). Validate activity before betting a new project on caffe.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use write-you-a-vector-db

- If you require a production-ready vector database solution, as this is primarily a tutorial and not intended for direct deployment scenarios.
- When detailed licensing information is necessary for your project's compliance requirements, because the license of write-you-a-vector-db is unknown.
