# Base Invitation

> Manage permissions at the base level — invite members to a specific base without granting access to the entire space, enabling more granular and secure data collaboration.

## What is a Base Collaborator?

A base collaborator is a member invited to a specific base only. Unlike space collaborators, they can only access the bases they've been invited to and cannot see other bases in the space.

## Adding Base Collaborators

Enter any base and click the `Invite` button in the top-right corner. Two methods are supported:

* **Invite by email**: Enter the recipient's email address, set the base permission level (e.g. "Creator"), and click **Send Invitation**.
* **Invite by link**: Switch to the "Invite via Link" tab to generate a dedicated invitation link. Copy and share the link — recipients can join by clicking it.

In the invitation panel, you can view all users who currently have access to the base:

* **Base collaborators**: Members invited directly to this base only.
* **Space collaborators**: Shown with a "Space" badge next to their name, indicating they are space-level members who automatically inherit access to this base.

The base offers four permission roles to support different levels of collaboration. For a detailed permission comparison, see [Permission Details](/en/basic/space/space-permission).

<Note>For finer-grained control at the table, field, or record level, use the [Authority Matrix](/en/basic/authority-matrix) feature.</Note>

| Role      | Description                                                                                          |
| --------- | ---------------------------------------------------------------------------------------------------- |
| Creator   | Can perform creation actions, modify table structure, edit automations, and enable authority matrix. |
| Editor    | Can modify data.                                                                                     |
| Commenter | Can comment on records but cannot modify data.                                                       |
| Viewer    | Can view but cannot comment.                                                                         |

## Use Cases

Base invitation is designed for external collaborators. For example, a freelance designer hired to organize an asset library can be invited to that base alone with **Editor** permission, without seeing any other bases in the space.

## Notes

* **Permission inheritance**: A space Manager automatically has full access to all bases in that space and cannot be downgraded at the base level.
* **Link security**: Anyone who obtains an invitation link can attempt to join the base. If a link is leaked, you can revoke it by clicking the X next to it in the invitation panel.

<Tip>When the [Authority Matrix](/en/basic/authority-matrix) and [Permission Details](/en/basic/space/space-permission) coexist, only **Manager** users are exempt from Authority Matrix restrictions — all other users are subject to it.</Tip>
