NextDeveloper is a hands-on learning platform that takes you from your first line of code to a portfolio employers can see. Instead of passively watching videos, you write and run real code directly in the browser.
What makes NextDeveloper different
- Browser-based IDE: No downloads or setup. The code editor uses Monaco — the same engine behind VS Code — and runs your JavaScript in a Web Worker or via the Piston execution API.
- Structured career paths: Each path is broken into modules and lessons that build on each other, but you can skip ahead if you already know the material.
- Instant feedback: Automated tests check your work so you know immediately when you have it right.
- Portfolio and certificates: Complete projects that can be pushed to GitHub and earn verifiable certificates.
Run your first lesson in three steps
- Visit the Career paths page and choose a path that matches your goal.
- Click Start learning free or go through the onboarding flow.
- Open the first lesson, read the instructions, edit the starter code, and press Run.
If you are not signed in, your progress is still saved locally. Sign up or sign in later to keep it synced across devices.
