Replit has updated the terminology for its creations from "Repls" to "Replit Apps" or simply "Apps" to better reflect the current scope of user projects and align with the company's naming conventions. Originally, Repls were named to honor the read-eval-print-loop (REPL) concept that promotes an intuitive understanding of programming by allowing users to write and test code directly in the browser, without additional tools. This concept dates back to Replit's early days and is rooted in the work of computer science pioneers L. Peter Deutsch and Edmund Berkeley. Since its inception in 2016, Replit has evolved from offering a basic two-pane coding experience to a platform where users can build comprehensive applications that integrate AI, databases, and various services, making the new name, Replit Apps, more fitting for its expanded capabilities.
