Replit (/ˈrɛplɪt/), formerlyRepl.it, is an American technology company. Founded in 2016, Replit developed anonline integrated development environment (IDE) also named Replit that supports various programming languages.[1] In September 2024, it released the first version of Replit Agent, anAI agent for automatingsoftware development, with which users can interact in natural language.[2]
In 2009, having seen significant advancements in browser and web technologies, Masad imagined a development environment built on the same premise asGoogle Docs; that is, allowing the user to write and share code all in a web browser. In 2011, he produced an earlyopen-source version of this concept, called "JSRepl".[3] Because Masad then spent a few years working at various companies,[1] includingUdacity andCodecademy, JSRepl was used for the in-browser tutorials of Udacity and Codecademy.[4]
Replit was founded in 2016 by theJordanianprogrammers Amjad Masad, Faris Masad, and designer Haya Odeh.[5][6] It was incorporated inSan Mateo.[7][8][9][10] Its name comes from the acronym REPL, which stands for "read–evaluate–print loop". Initially a collaborative coding platform, Replit became with Agent an AI-powered software creation ecosystem centered around the ability to build complete applications by describing them in natural language.
In July 2025, Replit announced a partnership withMicrosoft to integrate its development platform with Microsoft’s enterprise tools, including theAzure cloud infrastructure, making Replit’s services available through the Azure Marketplace.[11] That same month, Replit'sAI agent went "rogue" and deleted a client company's entire database during acode freeze, against the prompter's wishes.[12] This incident earned a nomination in the 2025AI Darwin Awards.[13]
