Built for developers who are serious about React.

Monaco editor + WebContainers. Your code runs instantly — no setup, no installs, no waiting. Just React.

Exit interviews gate every level. Behavioral, coding, and system design rounds. You can't fake it.

No. The Junior level starts from React fundamentals, so motivated beginners can start fresh. A little JavaScript familiarity helps, but it isn’t required — that’s what the early lessons are for.
Tutorials let you watch and copy. React Boss makes you write real code, pass real tests, and sit an AI exit interview at the end of every level — and you don’t advance until you actually pass. No skipping, no faking it.
You progress through a structured Junior → Mid → Senior path covering hooks, state, data fetching, performance, and architecture — building real React apps in the browser and finishing job-ready, not tutorial-dependent.
There’s a free tier available forever so you can start learning at no cost. A paid Pro plan unlocks unlimited sandbox time and AI interview credits for those who want to move faster.
Just a modern browser. The code editor and live preview run entirely in your browser — nothing to install, configure, or set up. Open a lesson and you’re writing React in seconds.
