5. ChromaAcquired
Best for: Developers who want a simple, free, self-hosted vector store for RAG and semantic search prototypes.
Open sourceSelf-hostableSelf-hosted, Linux, macOS, Windows
55.9
score / 100
Why switch from Zilliz Cloud
Much simpler to start with: an embedded open-source vector store for prototypes and small RAG apps, with a hosted option.
Pros
Apache 2.0 licence with no usage limits on the open-source version
Quick to start with pip or npm and an embedded local mode
Combines vector, BM25, full-text, regex and metadata search
Cons
Hosted Chroma Cloud is being wound down after the Replit deal
You run, scale and back up the database yourself
Future roadmap now depends on Replit's priorities
