Replit

Repl.it is an IDE and software development environment company making a browser application platform for coding in over fifty programming languages. It is headquartered in San Francisco, California, and was founded in 2016 by Amjad Masad and Haya Odeh. The company's platform gives users the ability to code in their browser using any platform, operating system, and device and features real-time collaboration tools for remote team software development. Repl.it is integrated with GitHub and comes with all the tools and resources required for hosting and deploying applications built on its platform. Repl.it is part of a shift toward cloud-based developer tools for developers to create a web app sandbox in their browser with collaborative tools to help teams develop faster.

Repl.it participated in the YC W18 cohort of Y Combinator and raised an estimated $120,000.

Repl.it's platform is developed to allow users to code in an environment where they can collaborate with others, learn how to code, build applications, and share those applications. Further, the platform allows users to create cloud-powered computers that Repl.it calls "repls," which come with storage for code and files, a database for their data, and a collaborative editor and console to help users code with others. Some of the collaborative features include a shared workspace where users can see real-time edits across files, message other users, and debug code together. Further, the platform allows users to share projects, ask for help, and learn from tutorials or use templates. The platform is integrated with GitHub to make managing the code files used in software projects easier. The company's IDE supports a range of programming languages, including JavaScript, Python, Go, and C++.

Ghostwriter is Repl.it's coding artificial intelligence tool which is developed to make coding faster. Ghostwriter does this by providing in-line code suggestions to help users complete code; highlighting any block of code the users want to be explained, which is done in plain English; transforming a piece of code that is not working as the way it is intended; and generating code to help users and developers solve their problem. Ghostwriter also offers proactive debugging, helping developers find code errors and offering suggested fixes to those errors. And the AI allows users to find and fix errors at runtime.
