Chroma

Chroma (Chroma DB) is an open-source, AI-native vector database (embedding database) for building LLM, RAG, and semantic-search applications. It provides storage, indexing, and retrieval for vector embeddings with metadata filtering, full-text and regex search, and multi-modal retrieval across text, images, and audio. Chroma is Apache-2.0 licensed and self-hostable via a single server, and is also available as Chroma Cloud, a serverless, usage-based managed offering. Its HTTP/REST v2 API is organized around tenants, databases, collections, and the records (embeddings) inside each collection - add, upsert, update, get, query (similarity search), and delete - and is the same interface used by the Python, JavaScript/TypeScript, Rust, and other client libraries.

Chroma publishes 6 APIs on the APIs.io network, including Collections API, Databases API, Query API, and 3 more. Tagged areas include Vector Database, Vector Index, Vector Search, Vector Store, and Embeddings.

Chroma’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.

Where this information came from

This is an independent, third-party profile of Chroma, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
