Webflow does actually allow you to invite users to collaborate on projects, so it is not accurate to say that it is not possible to invite users in Webflow. However, there are some limitations and considerations to keep in mind.
First, the ability to invite users depends on your Webflow plan. If you are on the Lite plan, you can collaborate with one other person. The Professional plan allows collaboration with up to two additional team members, while the Team plan allows collaboration with up to ten additional team members. So, the number of users you can invite may vary depending on your plan.
Second, inviting users to collaborate on a Webflow project grants them access to certain features and permissions. For example, invited users can make changes to the project, publish the site, and interact with the designer or editor interface. However, some features, like billing and account management, may only be accessible to the project owner.
Third, it's important to note that while users can be invited to collaborate on a project, they can only access and make changes to that specific project. They won't have access to other projects in your account unless they are explicitly invited to those projects as well. This helps maintain privacy and security, as you have control over who can access your projects.
Regarding your mention of Webflow being in beta, Webflow has been out of beta for quite some time. The platform has grown significantly and is now a robust tool used by thousands of designers and developers worldwide. The ability to invite users and collaborate on projects is a core functionality of Webflow and is not limited by the product being in beta.
In summary, it is possible to invite users to collaborate on projects in Webflow, and the availability and permissions for invited users depend on your plan. The product being out of beta allows for a stable and reliable user experience when inviting users to collaborate on projects.
