Replit

Replit is a browser-based coding platform that allows users to write, run, and deploy code entirely in the browser without any local setup. It includes an AI coding assistant called Ghostwriter that provides code completion, explanation, debugging, and generation within the editor. Replit supports dozens of programming languages and frameworks, and has become especially popular among students, educators, and beginners learning to code, as well as for rapid prototyping. The platform offers a free tier and paid plans.
