Replit

Replit is a coding platform that runs entirely in the browser, so there is nothing to install. You write code, run it and host it in the same place. That makes it popular with beginners, students and anyone who wants to try an idea quickly. Its AI features let you describe an app in plain language, and the Replit Agent sets up the project, writes the code, fixes errors and deploys it. You can then keep editing by hand or keep chatting with the agent to change things. It also has a code assistant for completions and explanations. Replit has a free starter plan, with paid plans for more compute, private projects and heavier agent use. It is especially good for prototypes and small apps where speed matters more than a perfect setup.
