Chroma: AI-Native Embedding Database

Chroma: AI-Native Embedding Database

Chroma is an open-source AI-native embedding database designed for simplicity and developer experience, making it easy to build AI applications with memory by storing, searching, and filtering embeddings and their associated metadata.

Features

Developer-First Design

Minimal API surface with intuitive Python and JavaScript clients that make it possible to get started with vector search in just a few lines of code, prioritizing developer experience above all.

In-Process & Client-Server Modes

Flexible deployment from in-process embedded mode for prototyping to client-server architecture for production, with seamless migration between modes without code changes.

Automatic Embedding

Built-in embedding functions supporting popular models (OpenAI, Cohere, Sentence Transformers, and more) so you can store raw documents and let Chroma handle vectorization automatically.

Metadata Filtering

Rich metadata filtering with support for where clauses on document metadata and content, enabling precise retrieval that combines semantic similarity with structured constraints.

Multi-Modal Collections

Support for text, images, and other data types in the same collection with appropriate embedding functions, enabling multi-modal search and retrieval workflows.

Persistent Storage

Durable storage with support for local persistence, cloud-hosted Chroma, and configurable backends for production deployments with data reliability.

Key Capabilities

  • Simple API: Add, query, update, delete with minimal boilerplate
  • Hybrid Search: Combine embedding similarity with metadata and document filtering
  • Multi-Tenancy: Collection-level isolation for multi-user applications
