Why SpikyMC

Six reasons to choose our launcher

Ely.by built-in

Your Ely.by account and custom skins work everywhere. Patch is bundled - no setup needed.

Portable builds for Windows and Linux

Unpack and run. No install, nothing outside the folder. Fits on a USB stick.

Own infrastructure

All metadata, translations, wiki, libraries, Maven, Java runtimes and releases served from our machine - no third-party API that can rate-limit or disappear.

Multiple instances & modpacks

Create unlimited instances with own mods, settings and Java version. Install and update modpacks from Modrinth, CurseForge, ATLauncher in one click.

Mod management from Modrinth & CurseForge

Install, update or remove mods directly from Modrinth and CurseForge inside the launcher. No manual file juggling.

Per-instance Java & arguments

Each instance gets its own Java version (auto-downloaded) and custom JVM arguments. No version conflicts between modpacks.

Installer

The .exe walks you through the setup and leaves a shortcut behind. It needs permission to write to Program Files, which is why there is a portable build as well.

Portable

Unpack the .zip anywhere and run the exe inside. Nothing is installed and nothing is written outside the folder - which also means nothing to uninstall.

Releases

Every published build, with what changed in it.

1.1.1October 11, 2026Latest

Fixed:

  • Sign-in with Ely.by via the button now works on every build. Non-portable builds previously sent an incorrect callback, which Ely.by does not accept.

1.1.0October 11, 2026Stable

Added:

  • Ely.by accounts: sign in with an Ely.by account, with custom skins and support for servers that only allow Ely.by
  • Ely.by game patch: automatic download and application of the Ely.by patch (always / for Ely.by or offline accounts / for Ely.by accounts only / never)

Changed:

  • Offline accounts accept any nickname, with no length/charset validation and no "allow invalid usernames" toggle

Fixed:

  • Localization
  • Issues from previous versions

Known Issues:

  • Sign-in with Ely.by via the button is broken in the non-portable builds, but signing in with a code still works. Workaround: use https://account.ely.by/code. The portable builds are unaffected. Fixed in 1.1.1.
