Count limits, file sizes, and length limits in AskTable.

The tables below list default limits in the product. Items marked “Adjustable” can be changed by system administrators in “System settings”; actual values depend on the deployment.

## Project resources

| Item                        | Limit                                 | Applies to                    | When exceeded                                    |

| Data sources                | 50 per project                        | Cloud                         | Creation rejected with `RESOURCE_QUOTA_EXCEEDED` |
| Data roles                  | 50 per project                        | Cloud                         | Same as above                                    |
| Data policies               | 50 per project                        | Cloud                         | Same as above                                    |
| Personal API keys           | 10 per project (all members combined) | Cloud and private deployments | Same as above; revoke unused keys first          |
| System integration API keys | 20 per project                        | Cloud and private deployments | Same as above                                    |

- Data source, role, and policy limits apply only on Cloud; private deployment scale is controlled by the license user count.
- API keys are counted by active status; expired but unrevoked keys also count. API key limits apply from 4.2.72; role and policy limits were raised from 5 and 10 to 50 in 4.2.70.
- Organization member and project counts are determined by the plan. See [Plans and usage](https://docs.asktable.com/en/organization/plans-and-usage).
