I built DraftCode.io — A modern, open LeetCode-style platform for coding challenges

Hey devs!

I recently launched DraftCode.io, a platform like LeetCode — but open, modern, and developer-friendly.

Built for learning, interviewing, and building coding skills, DraftCode lets you solve challenges, submit code, and get real-time feedback across multiple languages.

Features

• Code editor powered by Monaco (VS Code)
• Test case evaluation & scoring (custom or public problems)
• Docker sandbox for safe code execution
• AI-based problem generation (coming soon)
• User submissions with history and leaderboard

Tech Stack

• Frontend: React + Tailwind + TanStack Table
• Backend: Flask (Python) + PostgreSQL
• Execution: Judge0 API (via Docker)
• Auth: Firebase Auth
• Infra: Vercel (frontend), Railway/EC2 (backend)

Why I built it

LeetCode is great, but:

• Closed platform with limited community control
• No easy way to create your own challenges or build learning paths
• Difficult to customize or integrate into personal sites/tools

So I made DraftCode — a modular platform for running and solving code problems, perfect for:

• Interview prep
• CS clubs/bootcamps
• Internal dev challenges

Try it out

I'd love feedback!

• Would you use this as an alternative to LeetCode?
• What features would make it better for your workflow?
• Interested in an AI tutor for step-by-step solutions?

Let me know what you think!
