Tesseral is open-source, multi-tenant authentication infrastructure designed for B2B SaaS applications, runnable as a cloud service or self-hosted. It provides hosted customizable login pages, tenant-level admin controls, user impersonation, and works with any tech stack via an API-first design.

Use cases

• add authentication to a b2b saas product
• manage multi-tenant users with customer admin controls
• self-host an auth service instead of using auth0
• implement sso and scim for enterprise customers
• impersonate users for debugging and support
• customize hosted login pages to match my brand

When to choose

• you're building B2B SaaS and need multitenant auth out of the box
• you want an API-first auth service that works with any stack
• you need enterprise features like SSO, SCIM, and user impersonation
• you want the option to self-host rather than depend on a closed managed service

When to avoid

• you need a lightweight auth library embedded directly in your app
• your product is consumer-facing with no tenant/organization model
• you want a fully managed service and never intend to self-host
• you need deep customization beyond what hosted login pages allow
