Can I share my guest project with others?
Yes! Guest projects have the same sharing capabilities as regular projects. However, the link will only work until the project expires.
What happens when the 24 hours are up?
The project and all its endpoints will be automatically deleted from our system. This action cannot be undone.
Can I have multiple guest projects?
Yes, you can create multiple guest projects, but managing them is much easier through a free account where they are all listed on one dashboard.
No forms, no wait. Experience the fastest way to build mock APIs in the industry.
