Chroma is an open-source search infrastructure for AI products, providing fast, serverless, and scalable vector, full-text, regex, and metadata search.

Chroma offers an open-source search infrastructure specifically designed for AI applications. It provides capabilities for vector, full-text, regex, and metadata search, built on object storage for cost-efficiency and scalability. The platform is trusted by developers and supports various search types including sparse vector search (BM25, SPLADE) and semantic similarity search. The infrastructure is engineered for low-latency queries over billions of multi-tenant indexes, claiming up to 10x cheaper operations due to its object storage foundation and automatic data tiering. It is designed to be zero-ops, auto-scaling with usage, and requiring no manual tuning. Chroma also offers enterprise-grade features like BYOC in VPC, multi-cloud/multi-region replication, and point-in-time recovery. Chroma provides client libraries for Python, TypeScript, and Rust, enabling developers to integrate its search capabilities into their AI products. It also features dataset versioning, A/B testing, and roll-outs, along with command-line tools for development. The platform is available as a free-to-start cloud service or can be run locally via its open-source Apache 2.0 license.
