About

Gater.app - Stay pilot 
                                                                             
Gater.app automatically generates quizzes from GitHub Pull Request changes 
to test whether you actually understand the code you're about to merge.    
                                                                             
WHY IT IS NEEDED                                                            
                                                                             
The rapid introduction of AI coding agents has transformed how software is built. While these tools are excellent at producing correct syntax, they often result in vibe coded designs that feel right but haven’t been deeply reasoned about. Vibe coding is acceptable for implementation details, but it becomes risky when applied to system architecture and design decisions.

Gater exists to keep developers in the pilot seat.                                                                                 

WHO IT'S FOR                                                               
                                                                             
✓ Developers aiming to not be replaced by AI coding agents                                       
✓ Teams using AI code generation tools                                     
✓ Engineering managers requiring secure and maintainable software                     
✓ Anyone who wants to ensure they understand all code implications before merging
