Every plan runs zero-setup in your browser, with live input() and full timeline scrubbing. Free needs no card: 15 runs a day in one language you choose, single file only. Paid plans unlock all three languages (Python, JavaScript & TypeScript), multi-file projects with cross-file imports traced automatically, longer runs, and the libraries you reach for, like NumPy, pandas, lodash and more, preinstalled and ready to import (see the full list). Each starts with a 7-day free trial of that plan (cancel anytime; billed in INR via Razorpay). Students at partner colleges get a free first month, then ₹10/mo. Just sign in with your institutional email (verified at signup; no extra steps).
