Brian Vaughn has joined Replay to further develop React DevTools, enhancing its capabilities with features unique to a time-travel debugger, which will help make software more approachable. React, widely adopted since its introduction in 2013, is used by 80% of JavaScript developers, and its DevTools are considered a benchmark with over 3 million users. Vaughn's move to Replay offers a chance to re-imagine the DevTools interface, and Replay is inviting others interested in the future of debugging to join the conversation on Discord and GitHub.
