Zero-ops infra

Unlike legacy search systems, Chroma is a database you'll want to be on-call for.

Auto-scales with usage

No manual tuning

Serverless pricing

Chroma takes full advantage of object storage with automatic query-aware data tiering and caching.

Vectors are large: 1GB text → 15GB of vectors

Memory is expensive: $5/GB/mo

Object storage is not: $0.02/GB/mo

Enterprise

Chroma brings the security, compliance, education and operational model enterprises need with our Apache 2.0 architecture.

BYOC in your VPC, multi-cloud/multi-region replication, point-in-time-recovery ensure a resilient and scalable search system with the same 0-ops story as Cloud.
