Up to 70% increase in data throughput

Chroma released a rewrite of its JavaScript/TypeScript client (chromadb v3) with a significantly smaller bundle size and improved developer experience. A new CloudClient simplifies Chroma Cloud connections. Embedding functions are now installed separately rather than bundled. The client is compatible with Deno and serverless platforms like Vercel, and adds a .rows() method on get and query results for easier iteration. Install: npm install chromadb@^3.

Chroma Sync, Chroma Cloud's serverless ingestion service, now supports Amazon S3, GitHub repositories, and web crawling as data sources. The service handles parsing, chunking, and embedding automatically with queue-based retries and rate-limit awareness. Amazon S3 supports PDFs, images, and code with optional auto-sync; GitHub uses collection forking for efficient incremental updates; web uses a JavaScript-capable crawler with configurable depth. Pricing starts at $0.04/GiB processed.

Chroma Cloud is a hosted, production-grade deployment of Chroma built from everything we learned shipping the single-node engine, re-architected into a distributed system for scale. The API remains unchanged, allowing migration from single-node to cloud without rewriting applications.

Chroma Cloud can now automatically crawl and index websites. Users supply a starting URL and Chroma handles scraping, converting pages to markdown, chunking via Tree-sitter, and generating embeddings — no custom ingestion pipeline required. The resulting collections support hybrid search blending dense embeddings for semantic matching with BM25 sparse vectors for keyword precision. Designed for product docs, blogs, and support pages.
