What is Chroma?

Discover how Chroma can enhance your workflow

Chroma stores embeddings and documents for retrieval and hybrid search. Developers start with the open-source library, then move to Chroma Cloud for hosted durability, backups, and team access. The engine supports vector similarity plus full-text and regex filters, which improves relevance for RAG, search, and analytics. Getting started is straightforward: define a collection, upsert embeddings and metadata, and query with flexible filters. Managed plans include observability, usage-based billing, and role controls. Teams pick Chroma for fast prototyping that scales to production without rewriting code, while the Cloud’s “$0 + usage” starter makes costs predictable. Integrations, SDKs, and docs help ship features quickly.
