# Projects Users

By default, projects are only visible to the user who created them. Grant access to other users as needed.

## Managing Access

Click **Users** in the left sidebar to view and manage project access.

| Level         | Can View | Can Edit | Can Manage Users |
| ------------- | -------- | -------- | ---------------- |
| **Read Only** | Yes      | No       | No               |

## Real-Time Collaboration

OpenBrIM supports simultaneous collaboration using WebSocket technology. When one user makes changes, all other users with access see updates automatically. Changes are recorded in the revision history.

{% hint style="info" %}
**Working on different scenarios:** If you want to explore different options without affecting your colleague's work, duplicate the project. Each copy has its own independent revision history.
{% endhint %}

***

## Sharing Options

{% hint style="warning" %}
**Understanding share types:**

* **Project link:** Recipients with workspace access see the current project state (view-only unless given write access)
* **Revision link:** Recipients see only that specific snapshot, not subsequent changes
* **User access:** Added users can view full revision history regardless of their permission level
  {% endhint %}
