Replit

Replit is an online platform for writing, running and publishing software. Amjad Masad, Faris Masad and Haya Odeh founded it in 2016. It started as a browser based coding tool for learners and later became a tool for building full apps with AI.

Replit Agent builds apps from a plain English description. It sets up the code, database and login, tests the app and keeps changing it as the user asks. Users can then publish the app to Replit's hosting with a custom domain. Developers can still write code by hand in the same workspace, in many languages. Replit supports dozens of programming languages, from Python and JavaScript to Go and C++.

There is a free Starter plan with limited agent use. Paid plans give more agent credits, private apps and more computing power. Teams and Enterprise plans add shared workspaces and admin controls. Replit is used by students, founders, product managers and companies building internal tools.
