Epic ships Linux-ready launcher built with "vibe coding" agents

Epic Games dropped a preview of its rebuilt PC game launcher today. The company calls it "significantly faster" and — finally — officially supports Linux. But the features aren't the headline. The build process is.

Epic says the new launcher was written with "vibe coding": AI agents generating and reviewing code instead of human engineers typing it line by line.

Martin Keely, VP and GM of the Epic Games Store and Online Services, told reporters the team used agents to write, review, and replicate the core functionality of the existing launcher. The tools were "super helpful" for testing and replication, he said, and made the Linux port possible. The project consumed "most of this year." Even with heavy agent use, Keely stressed that developers directed the process and supervised every step. They haven't adopted the "no more manual code" model that leaked internally this week.

That leak came days after CEO Tim Sweeney announced a "huge pivot" Monday: shift developers to "maximum AI acceleration." The goal, Sweeney said, isn't doing the same work with fewer people — it's letting everyone build "more and better." Bloomberg reported this week that an Epic director on an unannounced Disney title told their team: "no more manual code." Keely acknowledged the launcher team is "on the same train," though their approach predated the official memo.

The preview is live now on Windows, macOS, and Linux. The old launcher stays accessible. Epic also confirmed plans to bring Fortnite to Linux via the new app. No hard cutoff for the full switch — migration happens when the new version feels "stable" and hits "feature parity" "everywhere it needs to" against the current launcher.

Context: Epic cut more than a thousand employees in March. Sweeney wrote in an internal memo at the time that the layoffs were "not related to AI," adding that if the technology boosts productivity, the company wants "as many great developers as possible creating great content and tech." The launcher is the most concrete proof-of-concept for that strategy so far. The real test is whether the speed gains hold up — or whether technical debt piles up and blows up later.
