Casdoor
Casdoor offers three main pricing tiers to fit different organization sizes. All plans include no extra charges per monthly active user, which is different from many other identity platforms.
The Basic plan costs $9 per month and works well for personal projects and small teams. You get support for up to 100,000 users, 20,000 monthly active users, OAuth and OIDC protocols, and basic technical support through tickets within 24 hours.
The Premium plan at $25 per month is designed for growing startups and small companies. This adds SAML, CAS, and LDAP support, custom domains, higher limits with up to 2 million users and 1 million monthly active users, plus faster 8-hour support response times and anti-bot protection.
The Enterprise plan costs $59 monthly and targets medium to large companies. It includes all Premium features with significantly higher limits, multi-region deployment, Azure Active Directory and Google Workspace integration, and advanced security features.
Stack Auth
Stack Auth offers transparent pricing that scales with your needs. The Free plan is perfect for individuals and small projects, supporting up to 10,000 users with unlimited projects and teams. You get one dashboard administrator and access to all core authentication features.
The Team plan costs $49 per month and increases your user limit to 50,000 users. It includes three dashboard administrators, with additional admins available at $49 each. This plan is ideal for early startups and small teams building their products.
The Growth plan at $299 per month removes all user limits entirely. You get unlimited users, projects, and teams, along with five dashboard administrators included. Additional admins cost $49 each. This plan is designed for growing businesses that need to scale without worrying about user count restrictions.
All plans include the same core features, with the main differences being user limits and admin accounts.
