Logto: The Open-Source Alternative to Auth0 You have Been Waiting For

When it comes to authentication and identity, developers often face a trade-off between feature-rich services and vendor lock-in. Logto changes that. It’s a modern, open-source identity solution that offers the same (or better) capabilities as Auth0, Cognito, or Firebase Auth, without forcing you into a specific stack or pricing trap.

Whether you're building a SaaS product, a consumer app, or a multi-tenant B2B platform, Logto was designed with your needs in mind.

Identity, Simplified, From Frontend to Backend

At the heart of Logto is the idea that authentication should be both developer-friendly and user-centric. It comes with a web-based admin interface, the Logto Console, that lets you configure everything from sign-in methods to user management, all with minimal setup.

Out of the box, it offers beautiful authentication flows: sign-up, sign-in, social login, Google One Tap, MFA, and more. All are customizable to match your brand and UX standards. Dark mode? Internationalization? Custom domain support? Covered.

But it doesn't stop at the frontend. On the backend, Logto exposes a powerful suite of APIs and supports modern protocols like OIDC, OAuth 2.0, and SAML. Whether you're connecting mobile apps, web apps, APIs, or IoT services, Logto is ready.

Built for Scale and Security

Multi-tenancy isn’t an afterthought, it’s a core architectural feature. Logto allows you to group users and resources into organizations, complete with per-tenant role-based access control, invitation workflows, and just-in-time provisioning.

Security is enterprise-grade. Multi-factor authentication, SSO with providers like Okta and Microsoft Entra, personal access tokens for programmatic access, and user impersonation for support teams, it's all there. Even machine-to-machine authentication is supported for those building microservices or automation workflows.

Logto is SOC 2 Type II certified, meaning your user data is protected with some of the strictest security and privacy controls in the industry.

Developer Experience That Just Works

You can install Logto in minutes thanks to its step-by-step guides and SDKs for over 30 frameworks. From React and Next.js to CLI-based tools, Logto integrates easily with whatever tech stack you're using, no framework restrictions, no surprises.

And if you're working across platforms or devices, Logto’s Omni sign-in experience ensures your users get consistent, secure access everywhere.

Why Choose Logto?

Because you want the power of Auth0 without the limitations. Because your team deserves a transparent, extensible identity solution that scales. Because open-source shouldn't mean compromising on UX or security.

Logto is built for the real world of modern app development, where flexibility, security, and control aren't negotiable.
