Better Auth
Better Auth is completely free to use with no costs or limitations. As an open-source project released under the MIT License, you can use it in any project including commercial applications without paying anything.
There are no usage limits, user caps, or features locked behind paid tiers. Every feature mentioned in the documentation is available to all users. This includes advanced capabilities like two-factor authentication, organization management, and all authentication methods.
The project is supported by the developer community and backed by Y Combinator. While the core framework remains free, the team behind Better Auth is building optional infrastructure services for scaling, but these are separate from the core library.
You can self-host everything on your own servers with complete control over your user data and no recurring subscription fees.

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.
