FusionAuth Coupon: Free Community

Deal Highlights

What is FusionAuth?

FusionAuth is a customer identity and access management (CIAM) platform that you can self-host for free with unlimited users. Login, registration, multi-factor authentication, single sign-on, passwordless auth, social login, and user management without the per-monthly-active-user pricing that makes Auth0 progressively more expensive as your application grows.

For startups, the auth pricing trap is real. Auth0 costs $230/month at 10,000 MAUs. At 100,000 MAUs, it is thousands. FusionAuth self-hosted is free for unlimited users, forever. The savings compound dramatically as your user base grows.

Key Features for Startups

Self-hosted with unlimited users is the fundamental differentiator. Run FusionAuth on your infrastructure. Docker, Kubernetes, or bare metal. Your user data stays on your servers, under your control. No per-MAU pricing, no user count limits, no vendor dependency. The cost of auth is the cost of your server ($10-50/month), not a per-user fee.

Complete authentication methods cover every login scenario: email/password with configurable password rules, social login (Google, Apple, Facebook, GitHub, LinkedIn, Twitter), passwordless magic links and WebAuthn/passkeys, multi-factor authentication (TOTP, SMS, email), and enterprise SSO (SAML 2.0, OIDC).

Multi-tenancy (called "Tenants") isolates user pools for different applications, environments, or customer organizations. Run development, staging, and production auth from one FusionAuth instance. Serve multiple products with separate user databases.

Customizable login experience, themed login pages, custom registration forms, consent management, and localization for any language. White-label the entire auth experience to match your brand.

Webhooks and events notify your application when authentication events occur, user registration, login, password change, account lockout, and custom events. Build reactive workflows that respond to auth activity.

Admin portal provides a web interface for managing users, applications, tenants, and security settings. Search users, reset passwords, manage sessions, and configure auth methods without API calls.

Advanced security features include brute force protection, rate limiting, breach detection (checks passwords against known breach databases), and anomaly detection.

Who Should Use FusionAuth?

Startups that want auth without per-user pricing, especially those with 10,000+ users where Auth0 becomes expensive. Companies that need data sovereignty, user data must stay on their infrastructure. Applications requiring multi-tenant auth for different customer organizations. Any developer who values owning their auth infrastructure.
