Bubble.io User Permissions: Building Fine-Grained Access Control
Basic roles cover 80% of SaaS products. But some products need per-resource ownership, department isolation, or granular capability flags. This guide covers every permission pattern in Bubble — from simple RBAC to fine-grained attribute-based control.
When Simple Roles Are Not Enough
Basic RBAC — Owner, Admin, Member, Viewer — covers 80% of SaaS products. But some products need finer control: a Member who can edit Projects but not delete them, or see financial data but not team settings. Or per-resource permissions: a Member who owns a specific Project has edit rights on that project even though they cannot edit others. This guide covers both patterns and when to use each.
Role-Based (RBAC)
Permissions derived from a fixed role. Owner can do everything. Admin can manage team. Member can create. Viewer can read. Simple to implement and reason about. Correct for 80% of B2B SaaS products.
Resource-Based (Per-Record)
Permissions derived from ownership of a specific record. The creator of a Project can always edit it, even if their workspace role would normally prevent it. Requires an owner field on every data type.
Attribute-Based (ABAC)
Permissions derived from multiple attributes: role + department + resource type + time of day. The most powerful and most complex. Appropriate for enterprise compliance-heavy products. Rare in Bubble SaaS.
Implementing Fine-Grained Permissions in Bubble
Pattern 1: Custom Permission Sets via Feature Flags
Option Set: Permission
can_create_projects
can_delete_projects
can_view_financials
can_manage_integrations
can_export_data
can_view_audit_log
// RolePermissions data type maps roles to permission lists
RolePermissions:
role → Workspace_Role (option set)
permissions → list of Permission (option set)
// Check permission in workflow or UI
Show “Delete” button when:
Search for RolePermissions [role = Current_Role]
:first item’s permissions contains can_delete_projects
Pattern 2: Resource Ownership (Creator Privilege)
Project:
created_by → User ← set on creation
workspace → Workspace
// Edit button visible when: Admin+ OR created_by = Current User
Edit button visible when:
Current_Role is in [Admin, Owner]
OR This Project’s created_by = Current User
// Privacy rule: edit permission
Privacy Rule condition:
Membership[Admin+]:count > 0
OR This Project’s created_by = Current User
Permissions: Edit ✓
Pattern 3: Department or Team-Level Isolation
Team:
workspace → Workspace
name → text
members → list of User
Project:
workspace → Workspace
team → Team ← project belongs to a team
visibility → option set (Team-only / Workspace-wide)
// Search scoped to accessible projects
Search for Projects where:
workspace = current_workspace
AND (visibility = Workspace-wide
OR team’s members contains Current User)
Choosing the Right Permission Architecture
| Product Type | Recommended Pattern | Complexity | Build Time |
|---|---|---|---|
| Standard B2B SaaS (< 5 roles) | RBAC with Option Set roles on Membership | Low | 1 day |
| Collaborative tools (docs, projects) | RBAC + Resource Ownership (created_by) | Medium | 2–3 days |
| Department-segmented workspaces | RBAC + Team-level visibility flags | Medium | 3–4 days |
| Highly granular enterprise permissions | Custom Permission Sets (option set flags) | High | 1 week |
| Compliance-heavy (healthcare, finance) | ABAC with full audit log | Very High | 2+ weeks |
