# Chroma > Open-source search & retrieval database with a hosted cloud for vector, full-text, regex, and metadata search. Chroma is an AI-native, open-source search and retrieval database used for semantic search and RAG. It supports vector, full-text, regex, and metadata search, and ships with Python and TypeScript clients. Developers can run Chroma locally for rapid prototyping or use Chroma Cloud to scale to terabytes with an object-storage–backed, serverless architecture. The cloud offers a web dashboard, API keys, collaboration, and usage-based pricing. ## Features - Vector search (semantic similarity) - Full-text search and regex querying - Metadata filters on collections and records - Collection forking and collaboration - Object-storage–backed persistence (cloud) - Python and TypeScript client SDKs - Dashboard for browsing/searching data and managing API keys - Serverless scaling with low-latency reads - LangChain, LlamaIndex, and Mastra integrations - CLI and client/server deployment options ## Integrations LangChain, LlamaIndex, Mastra, OpenAI, Google AI, Hugging Face ## Platforms WEB, API, DEVELOPER_SDK ## Pricing Open Source, Free tier available ## Links - Website: https://www.trychroma.com - Documentation: https://docs.trychroma.com/ - Repository: https://github.com/chroma-core/chroma - EveryDev.ai: https://www.everydev.ai/tools/chroma
