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.
