GoRails

A screencast platform teaching Ruby on Rails through practical, project-based tutorials and starter templates. Founded in 2014 by Chris Oliver as a solo project, the site grew organically by consistently publishing high-quality developer content and building a loyal community around Rails education. Revenue comes from monthly and annual subscriptions that unlock premium screencasts, series, and ready-to-use application templates. The platform now generates $83k per month, proving that deep expertise in a specific framework can sustain a highly profitable education business.
