Screenshots

Beautiful from the first launch

Real Blossom screens, no mock-ups. The launcher and the in-game menu share one theme, which you change in Settings.

The Blossom launcher on the Play screen: a welcome message, Minecraft 1.21.11 with Fabric, a large pink Play button, a cherry blossom and falling petals on a dark background.

Features

Everything for playing, in one place

Performance first, then everything else. Features marked “Coming soon” are being built — we switch them on here only once they really work.

  1. Available

    More FPS

    Install Sodium, Iris and other performance mods in one click, with their dependencies and checksum checks. No copying files by hand.

    The installed mods list: Iris and Sodium with on/off switches, and Fabric API below in the “Required by Blossom” group.
  2. Available

    Fast startup

    The first install downloads the game, Java and Fabric from official sources and verifies every file. After that, a fast index checks only what changed, so the game starts without the wait.

    Blossom downloading the game: a 24 % progress bar, file count, megabytes, speed and time left, and a list of active downloads.
  3. Coming soon

    Capes

    Original high-resolution capes that other Blossom players can see. Free.

  4. Coming soon

    Emotes

    An emote wheel on the B key and original animations that your friends playing with Blossom will see.

  5. Coming soon

    Wardrobe

    Change your skin from a file, a player name or a built-in library, with a 3D preview — right from the game.

  6. Available

    Mods from Modrinth

    Browse thousands of mods with filters, install them with their dependencies, switch them on and off and keep them updated. Blossom makes sure they work with Fabric 1.21.11.

    The Mods tab: Modrinth search with Fabric and 1.21.11 filters, and cards for mods such as Fabric API, Sodium and Iris Shaders with Install buttons.
The installed mods list: Iris and Sodium with on/off switches, and Fabric API below in the “Required by Blossom” group.

Coming soon

Benchmark results coming soon

We will show numbers only once they are real: a repeatable test, the same scene, and the hardware listed in a footnote. No estimates.

FAQ

Frequently asked questions

Is Blossom free?

Yes, Blossom is free. All you need is your own Minecraft: Java Edition account. Blossom's code, artwork, capes and emotes are protected by copyright (all rights reserved).

Is my Microsoft account safe?

You sign in on Microsoft's page in your own browser, so Blossom never sees your password. Tokens are encrypted by Windows and never end up in logs or on the game's command line.

Which Minecraft version does Blossom support?

Minecraft: Java Edition 1.21.11 with Fabric. Blossom downloads the game, Java and Fabric from official sources and checks every file.

Can I add my own mods?

Yes. The Mods tab searches Modrinth, installs required dependencies and warns about incompatibilities. You can also drop your own .jar files into the mods folder.

Does Blossom collect my data?

No. Blossom has no analytics, no telemetry and no crash uploads. The optional presence feature (the flower next to your name) stores your UUID, when you were last seen and a profile with the ids of your chosen cape and emotes on the Blossom server. The profile is deleted 180 days after your last sign-in, and you can turn presence off in Settings.

When are capes, emotes and the wardrobe coming?

They are being built. This page marks them “Coming soon”, and we switch them on only once they really work.

Is this an official Minecraft product?

No. Blossom is a fan project, not affiliated with Mojang or Microsoft. You play on your own, purchased Minecraft account.

Which systems does Blossom run on?

Windows 10 and 11, 64-bit.
