Espectral Client is a non-premium launcher: play Minecraft Java with no paid account, in offline mode. And if you own a premium account, sign in with the official Microsoft login. You choose per instance.

Sign in with your official Microsoft account and keep your UUID, skins and access to premium servers that require a verified account.
Ahead-of-time class cache (JEP 483) on JDK 25: classes arrive pre-linked and the menu shows up sooner.
One-click Fabric and NeoForge instances, a performance mod preset, and .mrpack modpack support.
Offline mode with no paid account for non-premium servers, plus official Microsoft login for premium servers. Importing your account from another launcher takes one click.
Full ES/EN interface with light and dark Horizon Glass themes.
Automatic Rich Presence and optional identity verification for the community.
uhc, uhc2, and 24h servers integrated with live status, and the client always up to date.
The installer is code-signed by the SignPath Foundation (free program for open source projects). If Windows shows a warning the first time, click "More info" → "Run anyway". You can verify the file with the SHA-256 below.
… Available for Ubuntu 24.04 and Debian (64-bit) as a .deb package. It needs libwebkit2gtk-4.1 on the system; the package declares it as a dependency so apt installs it automatically.
Or install with a one-line terminal command:
wget https://download.espectral.es/espectral-client/latest/espectral-client_amd64.deb && sudo apt install ./espectral-client_amd64.deb… If you are comparing alternatives to TLauncher, SKLauncher, Prism, LauncherFenix or Modrinth, here is what sets us apart:
A launcher that lets you play Minecraft Java with no paid Mojang/Microsoft account, in offline mode with the name you choose. Espectral Client is non-premium and also supports official premium login.
Yes. Create an offline account in the launcher and play on servers that accept non-premium, including Espectral servers. The launcher itself costs nothing.
Yes, completely free and open source: no ads, no paid features. Base Minecraft belongs to Mojang; the launcher charges you nothing.
Yes. Sign in with your official Microsoft account and keep your UUID, skins and access to premium servers that require a verified account.
No. Premium servers require a verified Microsoft account and offline mode does not work there. For those servers, sign in with your premium account in the same launcher.
Windows 10 or 11, 64-bit, with 8 GB of RAM recommended. The first run downloads JDK 25, loader and assets; after that everything is local.
Minecraft Java with one-click Fabric and NeoForge instances, a performance mod preset and .mrpack modpack support. Java 25 installs itself.
Espectral Client is free, open source and ad-free, with an English/Spanish interface, AOT-accelerated boots on JDK 25 and Espectral servers built in with live status.
Yes. The Modrinth App requires a premium Microsoft account; Espectral Client has Modrinth built in — search and install mods and .mrpack modpacks with SHA-1 verification — and lets you play with no premium account or your official one, in English or Spanish, free.
Yes. In offline mode you set your skin in the launcher itself. Capes and skins tied to a Microsoft account require premium login.
It is open source: every line is auditable. You can also verify the installer SHA-256 against the one published on this page before running it.
Windows and Linux (.deb for Ubuntu 24.04 and Debian) are already available. Mac and Android are still pending: the project is open and contributions are welcome.
From Settings → Apps, like any program. Game data stays in %LOCALAPPDATA%\espectral-client in case you come back.
No premium account or your Microsoft account: install Espectral Client on your Windows PC and get to the menu sooner.
