ChromaDB Has a Free API You Should Know About

ChromaDB is an open-source embedding database that makes it easy to build AI applications with memory. Store, search, and retrieve embeddings with just a few lines of Python.

Why ChromaDB is the Easiest Way to Add AI Memory

A developer building a chatbot needed semantic search over 50,000 documents. Setting up Elasticsearch with embeddings took a week. ChromaDB did it in 10 lines of Python.

Key Features:

• Simple API — 4 functions: add, query, update, delete
• Automatic Embeddings — Built-in embedding functions
• Metadata Filtering — Filter results by any metadata field
• Persistent Storage — SQLite-backed for easy deployment
• Multi-Modal — Text, images, and custom embeddings

Quick Start

pip install chromadb

import chromadb

client = chromadb.Client()
collection = client.create_collection("docs")

collection.add(
    documents=["Python is great", "JavaScript is versatile", "Rust is fast"],
    ids=["1", "2", "3"]
)

results = collection.query(query_texts=["fast programming language"], n_results=2)
print(results["documents"]) # [["Rust is fast", "Python is great"]]

With Metadata

collection.add(
    documents=["Deploy with Docker"],
    metadatas=[{"category": "devops", "difficulty": "beginner"}],
    ids=["4"]
)

results = collection.query(
    query_texts=["deployment"],
    where={"category": "devops"}
)

Why Choose ChromaDB

1. Simplest API — 4 functions to learn
2. Auto embeddings — no embedding pipeline needed
3. Zero infrastructure — runs in-process or as server
