JavaScript Editor — React IDE

Aug 7, 2026

COSMO AI is here. Describe what you want and it writes the component. Tidy a whole file in one tap. Or fix the error your app just threw, right where it appears in the console — and see it run straight away.

Your credits work in every Cosmovex app that has COSMO AI, so a top-up follows you around.
