🚀 The Challenge: Build Open Source Alternatives

Build something real. Make it open source. Win prizes. Help others break free from vendor lock-in.

We’re looking for applications that provide open alternatives to tools currently:

  • Behind paywalls
  • Limited by restrictive licenses
  • Missing open source equivalents

💻 Why Build with Leap?

Leap is an AI-powered development platform that builds full-stack applications with real backend services, APIs, and deploys to your AWS or GCP cloud — all from a single prompt. It’s built on top of Encore, our open source backend framework.

It’s never been easier or faster to build open source alternatives, which makes this hackathon the perfect opportunity to create something meaningful.
