Your game. Your server.
Your rules.
The only viable private server for Umamusume enthusiasts. Play the Global or Japanese game entirely offline and on your own terms. The whole game, on your own device, every rule is yours to change.
Gacha and gifts
Stop asking the gacha. Tell it.
Run any banner the game has ever had, build your own, and fill your account from the Gift Shop. Carats, cards, characters, tickets, refills: as much as you want.
- Every past banner, any day, any order
- Your own Scout banners and Legend Races
- Max every card in one click, or take it back down
Career tuning
Bend every rule of a career.
Thirteen sliders, all centred on the official game. Push training gains up, set failure to Never, make rivals brutal or friendship lightning fast. The training screen shows the new numbers, so what you see is what you get.
- Training, failure, luck, hints, energy, sparks and more
- One press back to Normal
- Pin exact numbers for testing builds
Live editing
Fix or change anything, mid-career.
Stats, aptitudes, skills, conditions, mood, energy, fans, even the turn. Edit it while the game is running, and every edit takes a backup first.
- Fast Learner, Charming, any condition
- Move the career forward or back
- Park a career and start another
Sync
Play any day the game has ever had.
Pick a date and the whole game follows it: its events, its banners, its home screen. Missed an event? It is back. See official and your server side by side.
- Start, end or extend any event
- Champions Meeting rounds in one click
- See what is coming next
Global and Japan
Both games. Both in English.
Play the Global game or the Japanese one from the same app, both in English out of the box: menus, careers, skills and race commentary, with nothing else to install. English is the first language of many: 26 are planned.
- Master Challenge and League of Heroes on Japan
- English names across the whole dashboard
- Switch the translation off any time
26
languages planned
The race engine
Races decided by a real engine.
Every race is simulated by a compiled engine: positions, pace, stamina, skills and overtakes. The game replays it exactly like a real race, and the same seed gives the same race.
- Careers, Legend races, Team Trials, Champions Meeting
- The game's own training formula and events
- All four Global scenarios, start to finish
Mods
Game modes that exist nowhere else.
Switch on a whole new way to play. Every mod is optional, off until you want it, and built straight into the server.
- Archipelago: a multiworld seed on its own save
- Derby Casino: permadeath, debt and a slot machine
- Twitch Derby: your chat joins your races
- Randomizer and Dream's Luck
Why switch
The official game decides for you.
Here, you decide.
The whole game
Not a demo. Everything is in there.
More than 350 of the game's server calls rebuilt one by one against what the real game does.
- Careers in every scenario
- Team Trials
- Champions Meeting
- Legend Races
- Clubs and friends
- Main and event stories
- Missions and login bonuses
- Jukebox and concerts
- Present box and shop
- Inheritance and sparks
- LAN play with friends
- Automatic backups
Built to be trusted
Safe to try. Easy to leave.
Your game stays untouched
The real client, not patched, repacked or injected. Only where it connects changes.
Five ways back
One button, a desktop shortcut, closing the app, a prompt at Windows sign-in, or uninstall. You cannot get stranded.
Local by default
Nothing is sent anywhere. The server answers only your PC unless you turn on LAN mode.
Backups of everything
Every edit is backed up first. Export all your saves as one file and take them anywhere.
For serious players
The most complete option.
Built for players who take it seriously.
Everything a dedicated player wants from a private server, and nothing in the way of playing.
Free
No price, no subscription, nothing locked behind a paywall. Download it and it is yours.
Plug and play
One file, one checklist, one Play button. No command line and no config files.
No waitlist
No invites, no applications, no queue. Download it and play today.
Professionally built
A native-compiled server and race engine, with thousands of real game requests replayed against every build.
Runs on your own computer
Your account details never leave your PC, and while you play the game never touches the official servers.
The most complete option
Global and Japan, English built in for Japan, an accurate race engine, a full control panel, and mods: Archipelago, Derby Casino, Twitch Derby, Randomizer and Big fields.
Try it
Take the control panel for a spin.
Click around. Send yourself carats, fill a gift basket, open Career tuning and drag the sliders, look inside a mod, pick a day to play. This is how it feels.
An interactive preview with demo data. Best on a larger screen. The real panel runs on your PC.
Our mission
Games end.
Yours doesn't have to.
Live-service games are made to change, and one day to stop. Events rotate out, banners never return, and when the servers close, everything you built goes with them. UmamusumeX exists so Umamusume stays playable: every day the game has had, kept and runnable on a computer you own.
Keep every day
Every banner, event and home screen the game has had, playable again, not just remembered.
Yours to keep
Careers, roster and saves live on your own disk, and keep working with no connection at all.
Free for everyone
No price and no gatekeeping. Preservation only works if anyone can take part.
Built to last
One self-contained app that runs offline, with backups you can carry to any PC.
We love this game. UmamusumeX is a fan project made out of that love, for the players who want to keep it.
Ready in a minute.
Start keeping your game today. Download, double-click, follow the green checklist, press Play. That is the whole setup. Free, forever.
