Auth.js is completely free and fully open-source. It is used in some of the biggest sites on the Internet like ChatGPT with 100+ million(!) users a week.

Therefore, it is easy to forget that Auth.js is created and maintained by actual humans! None of the individuals work on the project full-time, and they often dedicate their free time to support anyone from individuals to medium-size to billion-dollar companies.

It would not be possible without the generous support of our sponsors.
