Embeddings database designed for LangChain-era workflows
Chroma is the embedded vector DB that became the default for RAG prototypes. Drop-in for LangChain, LlamaIndex, and most OSS RAG stacks. Hosted Chroma Cloud launched in 2025. Best for prototypes and teams under 10M vectors. Production-grade only since the cloud product matured — self-host at scale still needs care.
Fastest path from RAG demo to RAG prototype.
Embedded Chroma in a Python notebook in 4 minutes. Migrated to Chroma Cloud when traffic justified it. The local-to-cloud path is genuinely smooth.
LangChain-first means we ship faster.
Chroma is the default in 80% of RAG tutorials. New team members pick it up in 30 minutes. We swap to Pinecone when scale demands but Chroma is the obvious starting point.
Embedded mode shipped a feature we couldn't otherwise.
We built an offline-first desktop product that ships a vector DB inside the binary. Chroma's embedded mode is the only realistic option at this size.
