Ruby OAuth maintains OAuth protocol libraries for Ruby and the small supporting gems that keep those libraries easier to test, document, and operate.
For support, security-adjacent coordination, and contributor questions, use Ruby Users Forum or Discord.
Use Ruby Users Forum for longer support threads and protocol coordination. Discord is available for live coordination.
Support Ruby OAuth through Open Collective, GitHub Sponsors, or Liberapay.

Fun fact: the ruby-oauth project was the original OAuth project for Ruby. It is now more than 18 years old and began at Twitter when Twitter still ran on Ruby.
This project relies on contributors and sponsors. Please get involved.
