Highlighted rows are where these differ.
Chroma
- Best developer experience in the category
- Most teams outgrow it, which is fine
Best for prototypes and local development.
pgvector
- One database for vectors, rows and joins
- The honest default: reach for something else only when this stops working
Best for almost everyone, until scale says otherwise.
