Chroma.

TL;DR — Chroma is a developer-friendly embedding database for local-first and simple production RAG deployments.

What it is

It emphasizes easy setup and Python ergonomics for quick iteration.

Why it exists

Great default for prototypes and small-to-medium RAG apps.

Install

pip install chromadb

Basic usage

import chromadb
# add documents and embeddings
# query nearest chunks

When to use, when to skip

Use it when this category is a bottleneck in your agent stack and you want faster delivery with fewer custom components.

Skip it when your workload is tiny, requirements are fixed, or a plain provider SDK plus a few local functions is enough.
