Is there a free website prototyping service?

Question

Layouts and prototypes

Recommend a free web prototyping service.
Task: creating prototypes of personal account/admin pages (tables, lists, forms, etc.)
Requirements:
- free (free) access
- low entry threshold
- creation of active zones (event system)
- web version for collaboration (not critical)
Needed for a one-time creation of a prototype. Therefore, it makes no sense to use a paid service.
