FusionAuth — Free Community for Startups

Deal Highlights

FusionAuth — Customer Identity Without Auth0 Pricing

FusionAuth is a customer identity and access management (CIAM) platform that you can self-host for free. Login, registration, MFA, SSO, passwordless auth, and user management — without the per-MAU pricing that makes Auth0 expensive at scale.

Auth0 Alternative

Auth0 charges per monthly active user. At 10,000 MAUs, you pay $230/month. At 100,000 MAUs, it is thousands. FusionAuth self-hosted is free for unlimited users. The savings compound dramatically as you grow.

Complete Auth Platform

Email/password, social login, passwordless (magic links, WebAuthn), MFA, SSO (SAML, OIDC), user registration, consent management, and admin portal. Every auth feature you need in one platform.

Self-Hosted Control

Run FusionAuth on your infrastructure — Docker, Kubernetes, or bare metal. Your user data stays on your servers. Customize the login experience completely. No vendor dependency.

FusionAuth vs Clerk

Clerk provides beautiful pre-built UI components with minimal code. FusionAuth gives you more control with self-hosting and unlimited users. Clerk for speed. FusionAuth for control and cost savings at scale.

Getting Started

1. Self-host with Docker or use FusionAuth Cloud
2. Configure auth methods (social, email, passwordless)
3. Integrate using OAuth2/OIDC standards
4. Manage users through the admin portal

Pricing

Self-hosted Community is free forever with unlimited users. Paid plans add premium features and support.
