What are Marqo and OramaCore?
Marqo
Marqo is an open-source, end-to-end search engine that combines vector generation, storage and retrieval. It handles embedding creation automatically so you can run semantic search over text and images.
- Built-in embedding generation
- Text and image semantic search
- No separate ML pipeline needed
- Simple REST API
OramaCore
OramaCore is an open-source search and answer engine that combines full-text, vector and hybrid search with built-in LLM-powered answers. It is self-hosted as a single runtime.
- Hybrid full-text and vector
- Built-in answer engine
- REST API
- Self-hostable
