Epic releases a vibe-coded Epic Games Launcher preview for Windows, Mac and Linux

What did Epic release on 14 October?

Epic Games put a new version of its PC launcher, the app that holds the Epic Games Store, a player’s library, social features and Unreal developer tools, into public preview on 14 October 2026. The announcement on the Epic Games Store blog opens with a joke and a statement of method: “Programming is hard. So, instead of doing that, we vibe coded a new Epic Games Launcher that’s way faster and more responsive than the current one, and has a new look.”

The preview is available for Windows, macOS and, for the first time, Linux from a separate preview site. Epic calls the first release “a speedboat and not a yacht”: it has fewer features than the current launcher but is meant to start and switch views faster. Epic Games Store’s account on X put it more bluntly: “We vibe coded the Epic Games Launcher to be faster than the other guy.”

Installing the preview automatically uninstalls the legacy launcher, according to the preview site, though purchases, installed games, cloud saves and progress carry over because they are tied to the Epic account. Epic is not pushing the preview through the existing launcher; PC Gamer reports it expects adoption to spread by word of mouth while it fixes problems.

What Epic means by vibe coded

“Vibe coding” usually means describing what you want to an AI model and accepting the code it writes without reading it line by line. Epic used the phrase partly for effect, but its executives say AI did do much of the writing.

Martin Keely, who became general manager of the Epic Games Store in August, told PC Gamer that the team “started from scratch” with a completely new architecture for both the store and the launcher shell. “We did look at functionality that existed and said we want to replicate that, but not the code itself,” he said. AI “was a tool to write and review new features and new capabilities from the ground up in a different tech stack than what we had previously.”

Speaking to IGN, Keely said AI “made us more efficient and allowed a small team to rewrite the code base and be able to launch it faster across platforms.” He said the AI work focused on code efficiency and architecture, not on artwork or visual design, which Epic’s usual design group handled. Epic has not said which AI tools or models it used, how large the team was, or how much of the code engineers reviewed by hand.

How much faster Epic says it is

Epic’s preview site gives three head-to-head numbers against Valve’s Steam client. A cold start takes 5.47 seconds in the new launcher and 10.07 seconds in Steam, which Epic presents as 1.8 times faster. Moving from the background to the library takes 0.36 seconds against 0.42 seconds, or 1.2 times faster. Epic also says the new launcher opens its store three times faster than Steam opens its own.

The fine print matters. The figures are the “average of 5 tests on each of 13 machines, excluding the 3 lowest-end machines tested,” run in October 2026 by Keywords Studios, which the site describes as an independent third party commissioned by Epic. Leaving out the slowest machines may flatter the averages, and Epic has not published per-machine results, hardware lists or how Steam was configured.

PC Gamer, which saw a demonstration before launch, reported that Epic claims to have halved the launcher’s startup time and to reach the store page from a cold start 46% faster than Steam. The outlet said the speed-up looked significant in the demo but that it had not tested the client itself. The preview site’s headline also promises a library that is “30x faster” without stating what that is measured against.

What the preview does and does not do yet

The redesign centres on the library. Each game gets its own page with status, activity, play controls and add-ons. Players can switch between a details view and a grid, sort and filter by platform and genre, hide games, group titles into visual collections and connect other PC libraries so games installed through other stores show up alongside Epic purchases. A downloads page shows live download, read and write speeds and lists active, queued, scheduled and failed downloads. Parties and voice chat link to Fortnite and the Epic Games app.

System requirements match the legacy launcher, Epic says: Windows 10 or 11 on 64-bit, macOS 12 or newer on Apple M1 or later (Intel Macs are not supported), and 4 GB of RAM. Linux builds officially support Ubuntu 22.04 LTS or newer, Fedora 43 or newer and Debian 12 or newer on x86-64.

Some legacy features, including certain social features and account management options, are missing for now. Epic says that once a player is in a game or developer tool, nothing prevents casual or competitive play. Bug reports go through a Send Feedback button, Discord and Epic’s developer forums.

Linux support and the Easy Anti-Cheat rebuild

The launcher runs natively on Linux, but many games in the store are Windows-only builds that need a compatibility layer, so Epic tells players to check each game first. The biggest absentee is Fortnite, which Epic has kept off Linux because its anti-cheat protection there is weaker than on Windows.

In a technical post on Epic Online Services, Epic says it is rebuilding Easy Anti-Cheat for Linux as EAC Linux v2 and will pilot it in Fortnite first. Unlike Windows, where EAC relies on a kernel driver, v2 will not load a kernel module. It uses a systemd service that runs only while a protected game is open, eBPF programs, and existing kernel features. Players will need a kernel and modules signed with a well-known key, TPM 2.0, Secure Boot, measured boot, IOMMU on desktops, kernel lockdown in integrity mode, kexec disabled and the BPF security module active.

Epic lists the signing keys it currently accepts, including those used by Ubuntu, Fedora, Debian, openSUSE, Universal Blue (Bazzite and others), Rocky Linux and AlmaLinux, and says it wants to make the list open source. Steam Deck does not support the required features; Epic says it is talking to Valve. No date has been given for Fortnite on Linux.

Why Epic is putting AI in the headline

Most game companies that use AI coding tools do so quietly. Epic is making it the pitch. Two days before the launcher preview, chief executive Tim Sweeney wrote on X that “we have a huge pivot underway here at Epic, moving developers around to retool for maximum AI acceleration,” adding that the aim is to build “MORE and BETTER stuff,” not to do the same work with fewer people.

That post followed Bloomberg’s report that Epic told the team on an unannounced Star Wars and Marvel shooter to work “AI first.” We covered Epic’s AI-first pivot and its reported delays on 13 October. The launcher is the first product Epic has shipped and labelled as built this way, which makes it a public test of the strategy.

The pitch also echoes a wider shift toward software assembled by prompting, from hobby projects to Google’s plan to host personal vibe-coded apps in the Play Store. The difference here is scale: a storefront that handles payments and millions of game libraries.

What the claims leave out

Speed is the easiest thing to measure in a rewrite and the one Epic chose to advertise. Reliability, security and maintainability take longer to show. Research has found that AI coding agents tend to increase how much code is written faster than teams can review it; our report on a Harvard study of coding agents describes that review bottleneck. Epic has not described its review or security testing for the new launcher.

Epic itself flags the trade-off. “Will it have some bugs? Yes,” its store account posted. The company is treating the release as a beta, with feature parity promised but not dated. Until independent tests and a few months of updates arrive, the speed claims are Epic’s, measured by a firm Epic paid, on machines Epic selected.
