Fully isolated instances
Each instance keeps its own mods, config and worlds, so changing one never touches another. Switching versions needs no reinstall.
Closed beta · Built-in AI assistant
KLP Launcher manages your instances, mods, worlds and servers. What to install, which server to join, how to fix a crash — just ask it.
Free · No ads · Microsoft sign-in pending approval
Features
Isolated instances, mod management, world backups, multiple accounts, faster downloads. No third-party plugins, no hand-editing config files.
Each instance keeps its own mods, config and worlds, so changing one never touches another. Switching versions needs no reinstall.
Search, install, update and disable from the same list. Dependencies are pulled in automatically, and version conflicts are flagged before you install.
Back up on a schedule or snapshot by hand. Deleted the wrong thing, or corrupted a world? Roll back to any point in time.
Microsoft sign-in is being integrated and will be available once approval goes through. Several accounts can be saved at once, and switching takes two clicks, no restart.
Regional mirror nodes with multi-threaded downloads, and the concurrency is adjustable. Installing a large modpack no longer means waiting behind a proxy.
When the game crashes, the launcher reads the log, points at the mod and the line, and suggests a fix you can act on.
AI assistant
It can read your instances, mod lists and crash logs. Find a mod, install a modpack, track down a conflict — one sentence is enough. Anything that touches your files opens a confirmation card first, spelling out what it will do and which instances it affects. Nothing runs until you approve it.
Mod versions, loader, Java runtime and crash logs are all visible to it — no copy-pasting required.
Installs, deletions and config changes open a confirmation card that states what changes and which instances are affected. Cancel any line item.
Irreversible things like deleting an instance use a red primary button and list exactly what goes and what stays.
Point it at your own model endpoint and key in settings — or turn the AI off entirely.
This modpack keeps crashing, can you look?
The log shows a version mismatch between Sodium 0.5.3 and Iris 1.7.3. Upgrading Sodium to 0.6.0 fixes it, and I will add two missing dependencies while I am there.
Upgrade Sodium to a build that matches Iris 1.7.3 and add two missing dependencies.
Server directory
Filter by version, game type and loader, with live player counts and ping. Hit Join and the launcher matches the right instance, adds any missing mods, and runs a check before you connect.
Content
Connected to Modrinth and CurseForge, with mirror nodes for faster downloads. Before installing, it tells you which instance fits and what dependencies are missing.
Interface
No showy motion, no decoration for its own sake. Everything you do often is within two clicks.
A list view, one row per instance, with the play button always in the same place.
Mods, resource packs, shaders and modpacks in separate tabs, filters pinned to the top.
Every download and install in one place — pause, cancel or retry.
FAQ
Microsoft sign-in needs Minecraft API access approval from Mojang. That application is still in progress, so we cannot promise a date yet — once it goes through, you sign in directly in the launcher. Multiple accounts can be saved and switched at any time.
Yes. Import an existing .minecraft directory or another launcher's instance folder and the mods, worlds and config are all picked up. The original directory is left untouched.
No. Every write goes through a confirmation card you have to approve, and deletions list their full scope separately. You can also turn the AI off entirely in settings.
Mirror nodes and parallel connections are on by default. If it is still slow, switch to another source in the Downloads section of settings, or lower the concurrency to avoid throttling.
Windows 10 and later (x64), and macOS 12 and later on Apple Silicon. There are no Linux builds, and no builds for x86 Macs. Java is downloaded automatically per instance, so there is nothing to install yourself.
No. The launcher is free to download and use, with no ads and nothing bundled into the installer.
The portable build keeps its data next to the program, so the whole folder can travel on a USB stick and uninstalling means deleting it. The installed build stores data in your user directory. Features are identical. On read-only media the portable build falls back to storing data the way the installed build does.
The launcher is applying for Minecraft API access from Mojang. Until that is approved, no download is offered here. Once it goes through, builds will appear on this page — free, no ads, nothing bundled in.
