Replit

Replit is a browser-based development platform where Replit Agent builds apps from a description, then hosts them. It handles the database, authentication, secrets and deployment in one place. It is used by beginners, founders and professional teams.

Replit Agent plans the app, writes the code, tests it in a built-in browser and fixes problems it finds. Free Mode lets you chat and build with included models, while paid plans add credit for stronger models and private deployments. You can still open the code editor, shell and multiplayer collaboration at any time.
