Our fully managed hosted service, Chroma Cloud is here. Sign up for free. Chroma Cloud is a managed offering of Distributed Chroma, operated by the same database engineers who build Chroma. Chroma Cloud implements the same APIs as open-source Chroma, but runs on a distributed vector indexing system to support much larger scale than a single instance of open-source Chroma. Chroma Cloud runs in multiple regions across AWS and GCP — each database stays entirely within the region you choose. Chroma Cloud is serverless - you don’t have to provision servers or think about operations, and is billed based on usage

​
Easy to use and operate

Chroma Cloud is designed to require minimal configuration while still delivering top-tier performance, scale, and reliability. You can get started in under 30 seconds, and as your workload grows, Chroma Cloud handles scaling automatically-no tuning, provisioning, or operations required. Its architecture is built around a custom Rust-based execution engine and high-performance vector and full-text indexes, enabling fast query performance even under heavy loads.

​
Reliability

Reliability and accuracy are core to the design. Chroma Cloud is thoroughly tested, with production systems achieving over 90% recall and being continuously monitored for correctness. Thanks to its object storage-based persistence layer, Chroma Cloud is often an order of magnitude more cost-effective than alternatives, without compromising on performance or durability.

​
Security and Deployment

Chroma Cloud is SOC 2 Type II certified, and offers deployment flexibility to match your needs. You can sign up for our fully-managed multi-tenant cluster running in AWS us-east-1 or GCP europe-west1, or contact us for single-tenant deployment managed by Chroma or hosted in your own VPC (BYOC). If you ever want to self-host open source Chroma, we will help you transition your data from Cloud to your self-managed deployment.

​
Regions

Chroma Cloud’s multi-tenant offering currently runs in two regions:
RegionSlugEndpoint
AWS US East (N. Virginia)aws-us-east-1api.trychroma.com (default)
GCP Europe West 1 (Belgium)gcp-europe-west1europe-west1.gcp.trychroma.com
Each database is created in a single region and stays there — your data is stored and processed entirely within the region you select. Pick the region when creating a database in the dashboard, or pass it when creating a database via the API. Existing US databases are unaffected; to move data to the EU, create a new database in gcp-europe-west1 and reindex. Connecting to a non-default region only requires pointing the client at the right host. See Connecting to a non-default region for SDK examples.

Dashboard

Our web dashboard lets your team work together to view your data, and ensure data quality in your collections with ease. It also serves as a touchpoint for you to view billing data and usage telemetry.

Advanced Search API

Chroma Cloud introduces a powerful Search API that enables hybrid search with advanced filtering, custom ranking expressions, and batch operations. Combine vector similarity with metadata filtering using an intuitive builder pattern or flexible dictionary syntax. Chroma Cloud is open-source at its core, expanded to support high availability and distributed workloads. Whether you’re building a prototype or running a mission-critical production workload, Chroma Cloud is the fastest path to reliable, scalable, and accurate retrieval.
