How Was Replit Founded?

Replit was co-founded in 2016 by programmers Amjad Masad, Faris Masad, and designer Haya Odeh in San Mateo, California

. The idea originated from Amjad Masad's earlier work on "JSRepl," an open-source project he created with Haya Odeh in 2009 to compile languages into JavaScript

. After working at companies like Yahoo, Facebook, and Codecademy, Masad and Odeh revived the concept of a browser-based programming environment, initially focusing on the education market before expanding to professional developers

. The name "Replit" comes from the acronym REPL (read–evaluate–print loop)

. In March 2021, the company changed its domain from "repl.it" to "replit.com" to emphasize the preferred pronunciation and address issues with the ".it" top-level domain
