Why Cactus

Everything you need, nothing you don't.

🚫

No ads, ever

Free and open-source. No tracking, no upsells, no premium tier — just you and your worlds.

🪶

Small & fast

A tiny native app built on Tauri + Rust — it uses your OS's web view instead of bundling a whole browser.

🧩

Mods made easy

Browse and install mods, resource packs, shaders and modpacks from Modrinth and CurseForge in a click.

🗂️

Organized instances

Per-version, per-loader instances you can drag into groups, give custom icons, and cover art.

🧵

Every loader

Vanilla, Fabric, Quilt, Forge and NeoForge — the right Java runtime is downloaded automatically.

🖥️

Run servers

Spin up dedicated servers with a live console, world manager, ops/whitelist, and one-command sharing.

🎨

Make it yours

Themeable backgrounds, gradients and decor, a movable dock, and click sounds you can toggle.

Auto-updates

Signed in-app updates — install the latest version with one click, right from the launcher.

A look inside

Cozy, and out of your way.
