The small things that add up
Crashes, explained
When the game crashes, the launcher names the cause and suggests a fix. Still stuck? Send the log for AI analysis — no key, no setup.
Your own server
Create and run a server right from the launcher — on Vanilla, Paper, Spigot, Bukkit, Forge, NeoForge, Fabric or Quilt.
Friends and co-op
A friend has a world open — hit “Play”: the launcher installs their modpack at the right version and connects you. Chat, invites and shared modpacks are built in.
Java is handled
The right Java for every version downloads by itself — no installers, no PATH.
Updates itself
New versions install in the background. If GitHub is out of reach, the update comes from our own mirror.
Open source
All of the code is open on GitHub: read it, suggest a fix or build the launcher yourself.
