1.1
30 September 2026
Changelog: added a built in JIT enabler! you no longer need to use StikDebug in order to enable JIT. this currently only supports iOS 17.4+, but I plan on adding a method that uses darksword in the future removed the swipe gestures that mostly just got in the way of deleting servers/files added support for java 8 on iOS 26+ added an "api keyless" way of downloading mods, modpacks, datapacks, and resource packs from CurseForge. technically it still uses an api key on the backend, but you're no longer required to enter one yourself in settings added an automatic resource pack merger, which allows you to install multiple resource packs on your server fixed issues with iOS 27+ fixed maxpro's bug, as well as plenty of other random bugs fixed playit.gg integration minor UI/UX enhancements added a couple of easter eggs removed herobrine

there haven't been many changes since the release candidate, it's only really been a few minor bug fixes. Since this is the 1.0 release, here's the list of most important features in the app: Ability to run minecraft servers (duh) Built in JVM downloader, pick between Java 8, 17, and 21 (or download all of them!) Server memory allocation slider Easy to use server creator, with support for several server softwares A file manager that allows you to easily manage several servers Network tunneling via playit.gg and UPnP support Integrated mod, modpack, resource pack, and datapack downloading via Modrinth and curseforge Keep alive, run the server in the background even with the screen off Server config GUI thank you to all of the beta testers!

4 March 2026
Changelog: Proper TrollStore support, TrollStore devices will now spawn the JVM in a seperate process, meaning you can freely stop/start the server without the app closing Keep Alive, JESSI can now run in the background, even in LiveContainer or if the screen is off! UI improvements and bugfixes There is now a built in tutorial in the app! On first app launch, you will be given a welcome message and be prompted to take a tour around the app JVM's will automatically download via backup mirrors if necessary Installation guides have been added to the github page under the wiki (the guide for ios 16.7/17.0.1-17.3.1 has not been written yet as I'm working on a separate app for JIT enabling on those versions, and that app has not been finished yet) Some easter eggs have been added :eyes: Removed Herobrine

Changelog: iOS 14, 15, and 26 are now supported! iOS 26 support on A15/M2 or newer is untested, and is unlikely to work. if it doesn't work, try enabling/disabling TXM support in settings JVM's are no longer shipped in the ipa, cutting down the filesize by 96%! you can choose exactly which java versions you want to download directly in the app now Improved memory slider and memory estimation Additional useful info in settings Fixed the UI on iPadOS Removed Herobrine if you haven't already, join the discord for devlogs, announcements, and to report bugs! discord.gg/aZ9HbYXKur
