Epic's new 'vibe coded' Games Launcher preview is out, 46% faster than Steam
Epic Games released a public preview of a rebuilt PC games launcher that it says was "vibe coded," describing it as faster, redesigned and now available on Linux alongside Windows and Mac. Epic claims the new launcher starts 46% faster than Steam from cold and 14% faster when restored from the system tray (a gain of about 0.06 seconds), and calls the new library "30x faster" without further detail; it says Keywords Studios ran the testing on its behalf. Epic Games Store VP and GM Martin Keely said the team rebuilt from scratch and used AI to write and review features, while developers supervised the whole process; the company suggests Unreal developers and competitive Fortnite and Rocket League players stay on the old launcher until feature parity arrives. The move follows CEO Tim Sweeney's announcement of a pivot to "AI-accelerated development," and a Bloomberg report that a director on an unannounced Disney title told staff there would be "no more hand-written code."
A major platform shipping an AI-assisted rewrite of a core client is a rare public test of whether "vibe coding" holds up in production software.
