Chroma

Chroma

Chroma is an AI-native open-source embedding database. It is the simplest way to build Python or JavaScript LLM applications with memory. Chroma gives developers the tools to store embeddings and their metadata, embed documents and queries, and search through the database for similar documents — a core building block for RAG and LLM apps.

Is Chroma free to self-host?

Yes — it is open source and runs on your own hardware.

Does Chroma need a lot of resources?

A server with 1–2GB RAM is enough for most workloads.

How do I deploy Chroma?

Easiest via Docker — see the installation guide for commands.

Where does my data go?

Nowhere — everything is processed locally on your server.
