Intro
Building software is exciting. Keeping it up to date is what slows everything down.
Every upgrade, refactor, and migration turns into weeks of work, coordination, and risk.
This hackathon is about changing that.
👉 Use AI + codemods to automate software maintenance 👉 Turn complex migrations into fast, reliable workflows 👉 Build tools that real teams can use in production
By the end, you won't just ship a project. You'll learn Codemod's open-source toolkit — adopted by Node.js, React, Express, React Router, Nuxt.js, pnpm, Webpack, MSW, i18next, and more, and make it your superpower for the rest of your career.

⚡ What You'll Do
1. Pick a real world upgrade or migration
2. Build codemods to automate it
3. Use AI to handle edge cases
4. Prove it works on a real repo
That’s it.
You’ll end up with a production-grade migration workflow: deterministic codemods handle most changes fast and reliably, AI steps cover edge cases, and it works across real-world repositories.
Goal: 👉 Automate 80%+ of the migration 👉 Minimize manual work 👉 Make it reliable enough for real teams

💰 Prizes
🎖️ Top Codemod Prize — Up to $3,000 total
The strongest submission can earn up to $3,000 in total by combining rewards across the three categories below: Production-grade Migration Recipes, Public Case Studies, and Official Framework Adoption.
---
How Submissions Are Evaluated: We evaluate submissions based on how much of the migration you automate, how accurate it is, and how well it works on real codebases.

Why This Matters: Every company struggles with maintenance — dependency upgrades, API changes, large refactors. It is a massive, mostly unsolved problem. If you get this right, you are not just building a hackathon project. You are building infrastructure that every engineering team needs.
