Spiky, but not spooky. 🌵
Cactus is a small, open-source Minecraft launcher — arrange your instances, install mods, run servers, and play together. No ads, no tracking, no bloat.

Free and open-source. No tracking, no upsells, no premium tier — just you and your worlds.
A tiny native app built on Tauri + Rust — it uses your OS's web view instead of bundling a whole browser.
Browse and install mods, resource packs, shaders and modpacks from Modrinth and CurseForge in a click.
Per-version, per-loader instances you can drag into groups, give custom icons, and cover art.
Vanilla, Fabric, Quilt, Forge and NeoForge — the right Java runtime is downloaded automatically.
Spin up dedicated servers with a live console, world manager, ops/whitelist, and one-command sharing.
Themeable backgrounds, gradients and decor, a movable dock, and click sounds you can toggle.
Signed in-app updates — install the latest version with one click, right from the launcher.








Free and open-source. Pick your platform to grab the latest build.
