Field validations can be expensive, especially custom validations that are async or highly complex. This can lead to slow form state response times when generating form state for many such fields. Ideally, we only run validations on fields whose values have changed. This is not possible, however, because field validation functions might reference _other_ field values with their args, and there is no good way of detecting exactly which fields should run in this case. The next best thing here is to only run validations _after the form has been submitted_, and then every `onChange` event thereafter until a successful submit has taken place. This is an elegant solution because we currently don't _render_ field errors until submission anyway. This change will significantly speed up form state response times, at least until the form has been submitted. From then on, all field validations will run regardless, just as they do now. If custom validations continue to slow down form state response times, there is a new `event` arg introduced in #10738 that can be used to control whether heavy operations occur on change or on submit.

Payload Multi-Tenant Example
This example demonstrates how to achieve a multi-tenancy in Payload. Tenants are separated by a Tenants collection.
Quick Start
To spin up this example locally, follow these steps:
- Run the following command to create a project from the example:
npx create-payload-app --example multi-tenant
pnpm dev,yarn devornpm run devto start the server- Press
ywhen prompted to seed the database
- Press
open http://localhost:3000to access the home pageopen http://localhost:3000/adminto access the admin panel- Login with email

- Login with email
How it works
A multi-tenant Payload application is a single server that hosts multiple "tenants". Examples of tenants may be your agency's clients, your business conglomerate's organizations, or your SaaS customers.
Each tenant has its own set of users, pages, and other data that is scoped to that tenant. This means that your application will be shared across tenants but the data will be scoped to each tenant.
Collections
See the Collections docs for details on how to extend any of this functionality.
-
Users
The
userscollection is auth-enabled and encompass both app-wide and tenant-scoped users based on the value of theirrolesandtenantsfields. Users with the rolesuper-admincan manage your entire application, while users with the tenant role ofadminhave limited access to the platform and can manage only the tenant(s) they are assigned to, see Tenants for more details.For additional help with authentication, see the official Auth Example or the Authentication docs.
-
Tenants
A
tenantscollection is used to achieve tenant-based access control. Each user is assigned an array oftenantswhich includes a relationship to atenantand theirroleswithin that tenant. You can then scope any document within your application to any of your tenants using a simple relationship field on theusersorpagescollections, or any other collection that your application needs. The value of this field is used to filter documents in the admin panel and API to ensure that users can only access documents that belong to their tenant and are within their role. See Access Control for more details.For more details on how to extend this functionality, see the Payload Access Control docs.
Domain-based Tenant Setting:
This example also supports domain-based tenant selection, where tenants can be associated with a specific domain. If a tenant is associated with a domain (e.g.,
gold.localhost.com:3000), when a user logs in from that domain, they will be automatically scoped to the matching tenant. This is accomplished through an optionalafterLoginhook that sets apayload-tenantcookie based on the domain.The seed script seeds 3 tenants, for the domain portion of the example to function properly you will need to add the following entries to your systems
/etc/hostsfile:- gold.localhost.com:3000
- silver.localhost.com:3000
- bronze.localhost.com:3000
-
Pages
Each page is assigned a
tenant, which is used to control access and scope API requests. Only users with thesuper-adminrole can create pages, and pages are assigned to specific tenants. Other users can view only the pages assigned to the tenant they are associated with.
Access control
Basic role-based access control is setup to determine what users can and cannot do based on their roles, which are:
super-admin: They can access the Payload admin panel to manage your multi-tenant application. They can see all tenants and make all operations.user: They can only access the Payload admin panel if they are a tenant-admin, in which case they have a limited access to operations based on their tenant (see below).
This applies to each collection in the following ways:
users: Only super-admins, tenant-admins, and the user themselves can access their profile. Anyone can create a user, but only these admins can delete users. See Users for more details.tenants: Only super-admins and tenant-admins can read, create, update, or delete tenants. See Tenants for more details.pages: Everyone can access pages, but only super-admins and tenant-admins can create, update, or delete them.
If you have versions and drafts enabled on your pages, you will need to add additional read access control condition to check the user's tenants that prevents them from accessing draft documents of other tenants.
For more details on how to extend this functionality, see the Payload Access Control docs.
CORS
This multi-tenant setup requires an open CORS policy. Since each tenant contains a dynamic list of domains, there's no way to know specifically which domains to whitelist at runtime without significant performance implications. This also means that the serverURL is not set, as this scopes all requests to a single domain.
Alternatively, if you know the domains of your tenants ahead of time and these values won't change often, you could simply remove the domains field altogether and instead use static values.
For more details on this, see the CORS docs.
Front-end
The frontend is scaffolded out in this example directory. You can view the code for rendering pages at /src/app/(app)/[tenant]/[...slug]/page.tsx. This is a starter template, you may need to adjust the app to better fit your needs.
