Wristband

Wristband is an authentication platform specifically designed for multi-tenant SaaS applications. It provides everything developers need to handle complex authentication scenarios where multiple customer organizations (tenants) share the same application but require isolated user management. The platform offers hosted login pages, tenant discovery flows, and comprehensive APIs for user management. What sets Wristband apart is its focus on the multi-tenant use case. It handles vanity domains for custom branding, allows per-tenant configuration of security policies like MFA and SSO, and provides SDKs for popular frameworks including Next.js, Express, Django, NestJS, and ASP.NET. The platform manages the entire authentication lifecycle from initial login to token management and user profile updates. Development teams building B2B SaaS products benefit most from Wristband. It eliminates the complexity of building secure, scalable authentication systems from scratch, allowing teams to focus on their core application functionality rather than security infrastructure. Real-world use cases include enterprise software platforms, subscription-based services, and any application that needs to securely manage multiple customer organizations within a single codebase.
