Web games on Epic

Your web game on the Epic Games Store

Windows and macOS builds of your HTML5 game, uploaded to Epic with BuildPatchTool from the dashboard. One button per platform, patches instead of full re-uploads, and nothing to install.

What Epic asks of you

Getting onto the Epic Games Store is a partnership, not a signup: Epic reviews your studio and your game before you get a product in the Developer Portal. Start that early, because Deskifier can’t shorten it.

Once you’re in, every release means a native build per platform and an upload with BuildPatchTool, Epic’s publishing CLI, which is only distributed through the partner portal. Doing it yourself means a wrapper like Electron, a build for each OS, Mac signing, and a machine set up to run the tool with your organisation’s credentials.

Deskifier handles the builds and the upload; the store page and release stay yours.

What your game gets on Epic

BuildPatchTool, run for you
Build & push packages the game and uploads it to the right artifact. No tool to install, no build to download and re-upload.
Windows and macOS
One artifact per platform, the way Epic models them. Epic’s launcher has no Linux client, so those are the two it takes.
Patches, not re-uploads
BuildPatchTool diffs against your last upload, so a small change to a large game uploads a small patch.
Credentials kept safe
Your BuildPatchTool client secret is stored encrypted and never sent back to the browser once saved.
A settings menu you didn’t build
Window mode, resolution scale, monitor and volume over your game, opened with a hotkey, a controller button or your own pause menu.
Saves that survive
Browser storage is backed up to a visible GameSaves folder and restored after a reinstall, with no code from you.

Web game to Epic in three steps

  1. 1
    Add your game
    Point Deskifier at your game’s URL, or upload your HTML5 build so it ships inside the app and plays offline.
  2. 2
    Paste your Epic credentials
    From Product Settings → BuildPatchTool Credentials in the Developer Portal: organisation, product, client and an artifact ID per platform.
  3. 3
    Build & push
    Push Windows and macOS from their buttons, then assign the new build to a release in the Developer Portal.

Frequently asked questions

Yes. You publish under your own account, with your product created in the Epic Developer Portal. Epic reviews studios before onboarding them, so start that before you plan a release date.

The BuildPatchTool credentials under Product Settings → General. EOS SDK clients are listed separately and won’t work with the upload tool; that mix-up is the usual cause of an authentication failure.

No. Epic’s launcher runs on Windows and macOS only, so those are the platforms Deskifier builds for Epic. Your Linux players can get the game through Steam, itch.io or a direct download.

Not yet. Epic builds get everything every Deskifier game build has (the settings overlay, save backup, offline play and Discord Rich Presence), but Epic Online Services features like achievements aren’t built in today.

Through the Epic launcher. Build & push a new version and assign it to a release; the launcher patches players’ installs. Deskifier’s own updater is switched off in Epic builds so the two never fight.
