API-first. Built for builders.

We built Nudj so developers never have to build gamification from scratch.

Every team we talked to was rebuilding the same things: points systems, leaderboards, achievement tracking, reward fulfillment. Complex systems that look simple but take months to get right. So we built a platform that gives you all of it through a clean, well-documented API. One integration and you get the full gamification stack — challenges, rewards, achievements, leaderboards, analytics — accessible through 240+ REST endpoints with type-safe SDKs. Explore our interactive docs at docs.nudj.cx to see for yourself.
