Replit is an AI app and website builder. You describe what you want, and Replit Agent plans, writes, tests and deploys a working app, with hosting, databases and authentication built in. There is a free Starter plan, and Core costs $20 a month, or $18 a month billed yearly.
What is Replit?
Replit started as an online code editor and has become one of the most popular AI app builders. With Replit Agent, you can go from an idea to a deployed app without setting up anything on your computer.
The Agent writes the code, connects a database, adds login and payments, tests the app and fixes errors. You can also build mobile apps, slides, animations and designs, and developers can still edit the code directly.
