Solve challenges, climb the leaderboard, and win high-quality developer gear. Free forever.

For the v1 launch, we ship physical prizes (T-shirts, stickers, and keycaps) within India only. Global participants can still compete for bragging rights and digital recognition badges.
At the beginning of each month, the winner will be contacted via the email associated with their GitHub account to collect shipping details.
