What are Marqo and RediSearch?
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
RediSearch
RediSearch, part of the Redis Query Engine, adds full-text search, secondary indexing and vector search capabilities to Redis. It enables fast querying over data already stored in Redis.
- Full-text search inside Redis
- Secondary indexing of Redis data
- Vector similarity search
- Aggregations and queries
Marqo vs RediSearch: key differences
Marqo is written in Python, while RediSearch is built with Rust. Licensing differs — Apache-2.0 for Marqo versus RSALv2 for RediSearch. RediSearch is the lighter option, starting around 512 MB of RAM against 4,096 MB for Marqo. RediSearch is the more established project (first released 2017), while Marqo arrived in 2022.
Why pick each one
Choose Marqo if…
- All-in-one vector search
- No external embedding service required
Watch out for
- Heavy GPU or RAM needs for models
Choose RediSearch if…
- Very fast, in-memory
- Reuses existing Redis
Watch out for
- Source-available, not OSI licensed
Frequently asked questions
Is Marqo or RediSearch better?
Neither is universally better. RediSearch has the larger community; both share a medium setup difficulty, so the decision comes down to features and licensing.
