New Livestream: How Banks Protect Their Apps with FAPI 2.0.
Native multi-tenancy for Duende IdentityServer and User Management. One deployment, many fully isolated spaces, upgrade-safe by default. Add-on also includes multi-issuer support: a distinct OIDC issuer per context, fully spec-compliant.
Multi-Issuer turns one Duende IdentityServer deployment into a host for every issuer your business operates. Brand portfolios, regional subsidiaries, and partitioned-trust deployments run under a single instance, each with its own OIDC issuer.
A space is Duende's isolation boundary. Each space gets its own users, configuration, clients, and branding, isolated at the storage layer. Run one deployment and serve one customer or one million, each fully isolated.
Spaces is available in preview now and will be included in this add-on at general availability.
Are you rolling your own custom stores, tenant discriminator columns, or tenant claims? Duende’s Multi-Tenancy offers tenant isolation that lives in your ASP.NET Core application, runs where you deploy, and scales without per-realm limits or per-organization pricing tiers.
Cost scales with your contract, not your customer count. Multi-Tenancy is included as a capability of Duende IdentityServer on eligible tiers:
Tier | Availability |
|---|---|
| Community Edition | Not available |
| Lite | Not available |
| Standard | Not available |
| Advanced | Add-on, $7,500 flat fee |
| Custom | Add-on, $7,500 flat fee |
See the IdentityServer pricing page for full tier details.
It's now the Multi-Tenancy add-on. Nothing about the multi-issuer capability, your license, or pricing has changed. Multi-Tenancy is the multi-issuer add-on with added Spaces for the same price.
Yes. A space is Duende's isolation boundary. A space is what other platforms call a tenant, organization, or realm.
Spaces is in preview with customers now. We'll announce general availability timing as preview feedback lands.
