Why Antfly
- Built-in model execution via Antfly Inference — no external API calls needed
- Hybrid BM25 + vector search in a single query
- Distributed consensus with Raft for production reliability
- Full document store with ACID transactions, not just vectors
- Multimodal search (images, audio, video) out of the box
Pricing
Antfly
Open source, self-hosted. Cloud pricing TBD.
Chroma
Open source. Hosted plans from $30/mo.
Antfly includes ML inference (Antfly Inference) at no additional cost.
Deep Dive
Chroma is a popular open-source embedding database designed for AI applications. It excels at simplicity and developer experience for vector storage and retrieval.
However, Chroma is primarily a vector-only store. If your application needs full-text search, structured queries, or production-grade distribution, you'll need additional infrastructure alongside Chroma.
Antfly provides all of these capabilities in a single binary — vector search, BM25 full-text search, document storage, and local ML inference — eliminating the need to stitch together multiple services.
