Project rate limits

Each project has a set of rate limit buckets. A bucket is a named group of API endpoints that share the same rate limit threshold. When a request comes in, Ory resolves which bucket the endpoint belongs to and applies the threshold for that bucket.

Bucket thresholds are determined by two factors:

  • Subscription tier: The project's subscription tier (Developer, Production, Growth, or Enterprise).
  • Project environment: The project's environment (Production, Staging, or Development).

For a detailed explanation of tiers and environments, see our Workspaces and environments guide.

Rate limits per bucket​

Buckets follow a {service}-{access}-{threshold} naming pattern. For example:

  • kratos-public-high: for endpoints with a high rate limit allowance
  • hydra-public-medium: for endpoints with a moderate rate limit allowance
  • hydra-admin-low: for endpoints with a low rate limit allowance
info

A bucket counter is shared across all endpoints in the same bucket. For example, POST /admin/relation-tuples and  DELETE /admin/relation-tuples both belong to keto-admin-high, so every call to either endpoint counts against the same limit. Plan your request volumes accordingly.

You will see two rate limits for each bucket:

  • Burst limit: Maximum requests per second (rps), allowing for short traffic spikes.
  • Sustained limit: Maximum requests per minute (rpm), ensuring consistent performance over time.

Identify the rate limits that apply to your project​

In the Project rate limit table below:

  1. Select your subscription tier from the Tier dropdown. Options are Developer, Production, Growth, or Enterprise.
  2. Select your project environment from the Environment dropdown. Options are Production, Staging, or Development.
  3. To search by API path, enter the API path into the Search API path box. The endpoint appears highlighted. Look to see which bucket it belongs to for its rate limit.

Project rate limits use a bucket system to group endpoints and apply thresholds. Understanding how buckets work will help you understand the project rate limit table below. See Project rate limits to learn how rate limits are applied per bucket.
