# Service Quotas Source: https://docs.chain.link/cre/service-quotas Last Updated: 2026-05-26 > For the complete documentation index, see [llms.txt](/llms.txt). This page documents the service quotas for Chainlink Runtime Environment (CRE) workflows. > **NOTE: Subject to change** > > The quotas documented on this page are subject to change. Check back regularly for updates. ## Per-organization quotas These quotas apply at the organization level. ### Organization membership | Quota | Description | Value | | ------------- | ------------------------------------------------ | ----- | | Maximum users | Maximum number of user accounts per organization | 40 | This limit can be increased. [Contact us](/cre/support-feedback) to request a higher user cap for your organization. ### Registry quotas | Registry | Quota | Value | | --------------------------------------------------------------------------- | ------------------------------------ | ----- | | Private registry (`deployment-registry: "private"`) | Maximum workflows per organization | 3 | | Public onchain registry (`deployment-registry: "onchain:ethereum-mainnet"`) | Maximum linked keys per organization | 1 | | Public onchain registry (`deployment-registry: "onchain:ethereum-mainnet"`) | Maximum workflows per linked key | 3 | > **NOTE: Subject to change** > > Registry quotas are being actively tuned ahead of general availability. Values may increase. Run `cre registry list` to confirm your organization's access. ## Per-owner quotas These quotas apply to each workflow owner (user account) within an organization. | Quota Key | Description | Value | | ------------------------------------------------------------------------------------------- | ----------------------------------------------------------- | ----- | | [`PerOwner.WorkflowExecutionConcurrencyLimit`](#perowner-workflowexecutionconcurrencylimit) | Maximum number of workflows that can execute simultaneously | 5 | | [`PerOwner.VaultSecretsLimit`](#perowner-vaultsecretslimit) | Maximum number of secrets that can be stored per owner | 100 | > **NOTE: Quota enforcement** > > When workflow executions exceed the quotas defined above, they are queued and automatically retried for up to 10 > minutes. If an execution cannot be completed within this 10-minute window, it will be dropped and will not run. ## Per-workflow quotas These quotas apply to each individual workflow. ### Workflow deployment quotas | Quota Key | Description | Value | | ----------------------------------------------------------------------------------------- | ------------------------------------------ | ------ | | [`PerWorkflow.WASMBinarySizeLimit`](#perworkflow-wasmbinarysizelimit) | Maximum size of the compiled WASM binary | 100 MB | | [`PerWorkflow.WASMCompressedBinarySizeLimit`](#perworkflow-wasmcompressedbinarysizelimit) | Maximum size of the compressed WASM binary | 20 MB | | [`PerWorkflow.WASMConfigSizeLimit`](#perworkflow-wasmconfigsizelimit) | Maximum size of the workflow configuration | 50 KB | ### Trigger quotas | Quota Key | Description | Value | | ------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | ----- | | [`PerWorkflow.TriggerSubscriptionLimit`](#perworkflow-triggersubscriptionlimit) | Maximum number of triggers that can be registered to a single workflow | 10 | ### Execution quotas | Quota Key | Description | Value | | --------------------------------------------------------------------------------- | --------------------------------------------------------------- | --------- | | [`PerWorkflow.ExecutionConcurrencyLimit`](#perworkflow-executionconcurrencylimit) | Maximum number of concurrent executions for a specific workflow | 10 | | [`PerWorkflow.ExecutionTimeout`](#perworkflow-executiontimeout) | Maximum total execution time for a single workflow run | 5 minutes | | [`PerWorkflow.WASMMemoryLimit`](#perworkflow-wasmmemorylimit) | Maximum memory allocated to a workflow | 100 MB | | [`PerWorkflow.ExecutionResponseLimit`](#perworkflow-executionresponselimit) | Maximum size of the data a workflow can return | 100 KB | ### General capability quotas | Quota Key | Description | Value | | ----------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ | --------- | | [`PerWorkflow.CapabilityConcurrencyLimit`](#perworkflow-capabilityconcurrencylimit) | Maximum concurrent capability calls (HTTP, EVM read/write, secrets) that can execute within a workflow | 30 | | [`PerWorkflow.CapabilityCallTimeout`](#perworkflow-capabilitycalltimeout) | Maximum time a single capability call can take to complete | 3 minutes | ### Secrets quotas | Quota Key | Description | Value | | ----------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- | ----- | | [`PerWorkflow.WASMSecretsSizeLimit`](#perworkflow-wasmsecretssizelimit) | Maximum total size of secrets accessible to a workflow | 27 KB | | [`PerWorkflow.SecretsConcurrencyLimit`](#perworkflow-secretsconcurrencylimit) | Maximum number of secrets that can be fetched concurrently.
