What is the Amazon BugBust?
The Amazon BugBust is a code challenge centered around a goal of fixing one million bugs in codebases around the world. Companies like yours can create private event that offer dev teams a fun and exiting way to earn rewards and recognition for their contribution to resolving issues.

Profiling groups

AWS CodeGuru is an AI SaaS that scans repositories to find bugs. We partnered with non-profits and the open-source community to scan their repositories, generating bugs to fix at the AWS re:Invent conference.

Fix bugs

Allow developers to browse, claim, fix, and earn points for bugs.

User testing

Research showed participants wanted to gamify bug-fixing within their teams.

Five developers loved the gamified concept and wanted to run it within their own teams. This led to a leader experience for setting prizes, importing bugs, and sharing results — plus clearer onboarding for game concepts.

Prizes

This is the prize information players see when they join this event. When the event ends, the event administrator tallys the event points and contacts the winners.
