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.
