Chroma review
A flexible vector database for multimodal retrieval, with a free tier and paid usage costs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Chroma is an open-source database and search infrastructure for AI applications. It stores documents, embeddings, and metadata for workloads such as agentic search, code search, and retrieval-augmented applications. Teams can run it locally, self-host it with persistent storage, or use Chroma Cloud as a managed serverless service. Its multimodal retrieval supports text, images, and audio, making it a fit for AI teams building retrieval systems across more than one content type.
Pricing is split across three plans. Starter costs $0 per month and includes 10 databases, 10 team members, Community Slack, and free credits, with usage-based charges applying. Team costs $250 per month and adds 100 databases, 30 team members, Slack support, SOC II, and volume-based discounts; usage-based charges still apply. Enterprise includes custom pricing, unlimited databases, unlimited team members, dedicated support, single-tenant clusters, and BYOC clusters. The paid entry point makes Chroma easier to evaluate than to budget for at larger usage levels, where both plan fees and usage charges matter.
The search feature set is unusually wide for teams that need several retrieval methods in one system. Chroma supports dense vector similarity search, sparse search using BM25 or SPLADE, hybrid ranking, metadata filtering, faceted search, full-text search, regex search, and document and metadata storage. Collection forking supports dataset versioning and rollouts, while command-line tools support operational workflows. Integrations include OpenAI, Cohere, Hugging Face, Sentence Transformers, Google Generative AI, Jina AI, Mistral, and Together AI. Choose Chroma for multimodal or mixed retrieval requirements and varied AI integrations; teams seeking a lower-cost paid plan may prefer an alternative.
