What Search Methods Does Chroma Support Beyond Vector Search?

Chroma supports dense vector search (semantic similarity), sparse vector search (BM25 and SPLADE for lexical relevance), full-text trigram search, regex pattern matching, and metadata filtering with faceted queries — all available within a single collection query.

How Does Chroma Collection Forking Work?

Collection forking creates an instant, copy-on-write snapshot of any existing collection. This enables A/B testing of different embedding models, staged index roll-outs, and dataset versioning without duplicating raw data or incurring full storage costs.

Can Chroma Run Fully Self-Hosted Without Chroma Cloud?

Yes. Chroma is Apache 2.0 licensed and can be deployed in embedded mode (in-process), as a self-hosted server, or via Docker on your own infrastructure. Chroma Cloud is the optional fully managed offering — the open-source core carries no cloud dependency.

What Are Chroma Cloud's Throughput And Scale Limits?

Chroma Cloud supports write throughput of up to 30 MB/s (2,000+ QPS) per collection, 200+ concurrent reads per collection, up to 1 million collections per database, and up to 5 million records per collection with 90–100% recall rates.

How Does Chroma Sync Handle Automated Data Ingestion?

Chroma Sync, launched in October 2025 and expanded in March 2026, allows collections to automatically ingest and re-sync data from external sources including Amazon S3 buckets, GitHub repositories, and public web URLs — eliminating manual ETL pipelines for retrieval workloads.

What is Chroma?

Chroma is an open-source, AI-native search infrastructure that gives developers a fast, serverless, and scalable database for building retrieval-augmented generation (RAG) pipelines and LLM-powered applications.

Supporting vector, full-text, sparse, regex, and metadata search in a single platform, Chroma eliminates the need for managing multiple search backends.

With over 15 million monthly downloads, 27K+ GitHub stars, and usage across 90K+ open-source codebases, it is among the most trusted vector databases in the AI developer ecosystem. Chroma Cloud extends the open-source core with a fully managed, zero-ops hosted service backed by SOC 2 Type II compliance.
