CMS item limits and collection scaling constraints

CMS Collection Capacity

Webflow enforces specific hard limits on the total number of items allowed per CMS collection based on the active site plan. These constraints apply to the aggregate count of entries within a single collection, regardless of their publication status.

Scaling and Asset Management

While referencing other collections does not increment the item count of the target collection, the total volume of entries remains a critical bottleneck during large-scale CSV imports. Asset limits for images and files are managed separately from these CMS item quotas.

When a site reaches its plan threshold, the system restricts the creation of new items until the plan is upgraded or existing entries are removed.

• What is the exact behavior of the import process when a CSV file contains more items than the remaining plan quota?
• Does the system provide a granular alert before the hard limit is reached to prevent data loss during bulk uploads?
