NEVER LOSE
A SAVE AGAIN.
Your saves, backed up automatically — and every version kept. Roll back a corrupted file, a bad night, or a regret. Co-op crews pass one world around like a cartridge, with a lock so nobody saves over anybody. Want to play live? Host a server on your own PC and your crew joins with no port forwarding.

POINT IT AT A FOLDER.
FORGET ABOUT IT.
HIT UPLOAD ↑
Grab a snapshot of your save folder and send a copy to the cloud. Each upload becomes its own labelled version — version one of many.
FLIP AUTO ON
Checkpoint64 checks your save folder every 60 seconds. If something changed, it waits for the game to finish writing, then uploads a fresh version on its own. Only the changed files get sent — the rest is skipped.
ROLL IT BACK
Click Versions → on any save to see every backup. Pick one and hit Restore — Checkpoint64 puts the files back and marks that version as the current one. Your 2am mistake becomes a 30-second fix.
WHAT'S IN THE BOX.
EVERY UPLOAD IS A VERSION.
Scroll through every backup with file count, size, and what changed since last time. Hit Restore and the files go back on disk, marked as current — no guessing, no “final_v2_REAL” folders.
ONE PERSON HOLDS THE WORLD.
Games like Factorio, Valheim, and Satisfactory have one live world at a time. Whoever holds the lock uploads; everyone else downloads. Holder gone quiet? Locks expire on their own, and you can take over — with a warning, and a logbook entry so everyone knows.
TINY UPLOADS.
Only the files that changed get uploaded — renamed files cost nothing extra. A 500 MB Minecraft world re-uploads as a few MB after a normal session, not the whole thing. Easy on your internet, easy on your storage.
SET UP IN SECONDS.
Presets for 520+ games — four flavours of modded Minecraft, Stardew, Skyrim, Palworld, Elden Ring — plus seven emulators. Pick which files count and skip the screenshots. If it writes saves to a folder, it works.
ONE WORLD, WHOLE CROWD.
Running a community world? Mint a join code and anyone holding it can download your save — but never upload over it. Codes are capped and revocable, and read-only visitors don’t use up seats. Every plan can host — 3 fans at once on Free, 15 on Lifetime, unlimited on Pro.
WHO DID WHAT, WHEN.
Every upload, restore, and lock-grab gets written down in your group’s logbook. Handy when your co-op partner blames you for the bad run.
STRAIGHT FROM STEAM.
Real reviews from real players, pulled live from our Steam page.
Really smooth program to operate. Seamlessly backs up my saves enough so when my mates decide to mess with my factory, I can reset the game pretty quickly. 10/10 hours saved.
I love this software. It lets me share my worlds between friends and my husband.
Very useful save management tool between friends, already saved us money from renting a dedicated server, even when your mate decides to remove something they shouldn't, we just rolled back to the version that didn't require fixing it. 10/10!
So easy to use even for a dumb dumb like me, who doesn't know much about software. Easy to keep control over your bits (game files, you dirty pig). Easy sharing with your mates, so you don't have to wait for them to be bothered to get online and play your multiplayer games…
