How to integrate Logto with Next.js?

Logto provides a Next.js SDK with guides in the docs. Install it via npm, configure environment variables, and use built-in components for auth flows in both client and server-side rendering.

Logto vs Auth0: which is better for startups?

Logto is open-source and cost-effective for self-hosting, while Auth0 offers a more mature managed service. For startups with DevOps resources, Logto saves on licensing but requires setup time.

Does Logto support social logins like Google?

Yes, Logto includes connectors for Google, Facebook, and other IdPs. You can set them up in the dashboard and customize the sign-in experience with a few clicks.

How to self-host Logto on Kubernetes?

Use the provided Docker images and Helm charts from the docs. Deploy PostgreSQL as a dependency, configure ingress, and set environment variables for scaling in production environments.

Is Logto compliant with GDPR or HIPAA?

Logto supports data residency and audit logs, but compliance depends on your deployment. Self-hosted versions give full control, while Logto Cloud may require reviewing their security policies.

Can I customize the RBAC roles in Logto?

Yes, Logto allows defining custom roles and permissions through the admin console or API. You can assign them to users or organizations for fine-grained access control.

What is Logto?

Logto is an open-source authentication and authorization infrastructure built for SaaS and AI applications. It provides a complete identity management solution that handles OIDC, OAuth 2.1, and SAML protocols while offering enterprise features like multi-tenancy, SSO, and RBAC. The platform solves the complexity of implementing secure authentication systems for modern applications.

Target Audience

Development teams building SaaS products, AI applications, or agent-based platforms that require enterprise-grade authentication with multi-tenancy support. It's particularly valuable for developers who want to avoid the complexity of implementing OIDC/OAuth protocols from scratch.

Value Proposition

Developers choose Logto because it provides a complete, production-ready authentication solution with enterprise features built-in, eliminating the need for custom workarounds. Its modern architecture specifically supports AI applications and agent-based systems while offering extensive framework SDKs and protocol support.

Legacy systems tightly coupled to specific, unsupported identity providers not covered by Logto's connectors.
Projects with minimal infrastructure budget where free tiers of managed services like Auth0 suffice without self-hosting.

Pros & Cons

Pros

Enterprise Features Built-In

Includes multi-tenancy, SSO, and RBAC ready-to-use without custom workarounds, as emphasized in the README for SaaS apps.

Wide Framework Support

Offers SDKs for over 30 frameworks like React and Go with pre-built, customizable sign-in flows, speeding integration.

Full Protocol Compliance

Supports OIDC, OAuth 2.1, and SAML out-of-the-box, handling complex authentication standards seamlessly.

AI Architecture Ready

Designed for Model Context Protocol and agent-based AI apps, making it future-proof for modern architectures.

Cons

Self-Hosting Complexity

OSS deployment requires managing PostgreSQL and Docker, adding infrastructure overhead compared to fully managed alternatives.

Ecosystem Immaturity

As a newer project, it has fewer community plugins and integrations than established options like Keycloak or Auth0.

Vendor Lock-in Risk

Using Logto's specific SDKs and UIs can make migration challenging if switching to another auth provider later.

Open Source Alternative To

Logto is an open-source alternative to the following products:

Firebase

Firebase is a Google-backed platform for developing mobile and web applications, providing backend services like authentication, databases, and hosting.

Cognito

Amazon Cognito is a cloud-based service that provides user authentication, authorization, and user management for web and mobile applications.

Auth0

Auth0 is a cloud-based identity and access management platform that provides authentication and authorization services for applications. It supports single sign-on, multi-factor authentication, and social login integrations.
