Unique: Implements API key authentication and token bucket rate limiting at the FastAPI middleware layer, with configurable per-key quotas. The rate limiter tracks state in-memory and can be extended with external backends (Redis) for distributed deployments.

vs others: More flexible than Pinecone's fixed rate limits because Chroma's rate limiting is configurable per deployment; more lightweight than Weaviate's OIDC integration because Chroma uses simple API keys suitable for service-to-service authentication.
