Chroma vs. Redis
Compare Chroma vs. Redis by the following set of capabilities. We want you to choose the best database for you, even if it’s not us.
Chroma vs. Redis on Scalability
No. Redis primarily operates by keeping data in memory. The classic architecture of Redis does not inherently follow the storage-compute separation architecture. Instead, it tightly couples data storage and computation in the same node or instance to ensure data access performance.
No. Can not scale beyond single node.
No. It only scales at the server level. In addition, you need to reshard all the data when scaling out a Redis cluster.
Yes - built-in replication; HA provided in an additional layer by Reis Cluster or Redis Sentinel)
No distributed data replacement
With Redis Enteprise
Chroma scalability
Without any distributed data replacement, Chroma is not able to scale beyond a single node
Redis Scalability
High Availabiltiy can be achieved with Redis Enterprise.
Chroma vs. Redis on Functionality
Performance is the biggest challenge with vector databases as the number of unstructured data elements stored in a vector database grows into hundreds of millions or billions, and horizontal scaling across multiple nodes becomes paramount.
Yes with scalar filtering
Yes - Pre-filtering documents against an index containing searchable fields
1 (HNSW)
HNSW & IVFFlat
Chroma functionality
Chroma uses HNSW algorithm to support kNN search.
Redis
Redis has supprt for similarity queries search with the use of vector fields; It is important to note that the k default LIMIT is 10.
Chroma vs. Redis on Purpose-built
What’s your vector database for?
A vector database is a fully managed solution for storing, indexing, and searching across a massive dataset of unstructured data that leverages the power of embeddings from machine learning models. A vector database should have the following features:
- Scalability and tunability
- Multi-tenancy and data isolation
- A complete suite of APIs
- An intuitive user interface/administrative console

Chroma is maintained by a single commercial company offering a non-scalable single node. License: Apache-2.0 license
Redis is an in-memory data structure store used as a database, cache, message broker, and streaming engine that has a vector field type for the storage, querying and indexing of vectors.
