Is FusionAuth worth the price?

85/100

FusionAuth offers a generous free Community tier, making it highly accessible.

The Starter tier at $125/month for 240K MAU is competitive, but the jump to Essentials at $850/month and Enterprise at $3300/month for advanced features and support is significant. It's best for businesses that need a robust, self-hosted CIAM solution with clear scaling options.

How is FusionAuth priced?

FusionAuth is available on a free tier, allowing users to get started without initial cost. For organizations with greater usage requirements or needing more advanced features, paid plans are offered.

Can FusionAuth be deployed on an organization's own servers?
