Epic Games claims its AI-assisted, "vibe-coded" launcher delivers a 46% advantage over Steam, according to a 2026 report from shattered.io.

The number comes from Epic itself. No third-party measurement, methodology note, or independent benchmark accompanies the claim. The 46% figure is an unverified vendor assertion, and readers should treat it as such until Epic publishes underlying data.

What is "vibe coding"?

"Vibe coding" (a development approach in which engineers describe desired behavior in natural language and an AI model generates the code, with minimal manual review) has moved from experimental to shipping product at Epic, if the report is accurate. The term implies the launcher was largely machine-generated rather than hand-engineered.

What changes for studios and developers?

The claim, if substantiated, would matter to PC publishers weighing storefront economics. Steam's dominant position has long constrained revenue splits across the market. A launcher with a measurable performance edge could shift distribution decisions — but only if the 46% figure survives scrutiny.

The report does not specify whether the 46% refers to:

• revenue per user,
• install conversion,
• engagement, or
• some other metric.

That omission is the central weakness of the claim.

What to watch

Epic has not, in this reporting, released methodology, sample sizes, or third-party audit. Watch for those disclosures — or a Steam counter-response — before pricing distribution strategy on a single contested number.
