Replit UI design & app screens

Replit is a browser-based coding platform that lets developers write, run, and collaborate on code in any language, increasingly with AI assistance. It serves learners, hobbyists, and teams building software without local setup.

The web app is a full IDE in the browser: file tree, code editor, console, live preview, and real-time collaboration, plus an AI agent for generating apps. Signature flows include spinning up a repl and building with AI. The design is dark and developer-oriented with multi-pane layouts and a friendly modern aesthetic, making it a strong reference for IDEs and developer tooling.
