Replit is a San Francisco-based start-up that provides an online integrated development environment (IDE) for software development. The platform is a Software as a Service (SaaS) that allows users to create online projects and write code in many supported languages.
Replit's key feature is collaborative coding, which allows users to share a project with one or many other users and see real-time edits across files, message each other, and debug code together. Replit also has a global community where programmers can talk, learn, and collaborate. Other features include syntax highlighting, code completion, debugging, hosting, unit testing, version control, package management, code generation via artificial intelligence, and more. With Replit, users can use any programming language via NixOS package database and can configure anything from the Language Server Protocol to debugger support.
