Checkpoint64

What it is

Checkpoint64 is a desktop application that automatically backs up PC game saves and maintains full version history. Players can roll back corrupted saves, bad patches, or unwanted decisions with a single click. The app watches the save folder rather than hooking into the game, allowing it to cover Steam Cloud gaps including emulators, modded installs, dedicated server worlds, and GOG or Epic copies.

For co-op gaming, Checkpoint64 implements server-enforced locks so only one player holds the world at a time, preventing overwrites while maintaining a shared activity logbook. It supports over 450 games and seven emulators with presets. The app checks for changes every 60 seconds and uploads only modified files, keeping internet usage and storage efficient.

Checkpoint64 offers a free plan with no expiration timer, a Lifetime one-time purchase option, and a Pro plan for larger crews. All plans include automatic backups, version history, co-op locks, and the ability to share worlds with read-only share codes.

Questions from the bench

What counts as a save?

Whatever the game writes to the hard drive. Checkpoint64 treats files in a folder as one save and backs them up together. It has presets for 450+ games and seven emulators; for other games, users point at the folder and pick the files.

Does it upload while the game is running?

Yes, carefully. Checkpoint64 checks the folder every 60 seconds and never locks save files. If the game is mid-save, it waits for activity to stop and tries again, preventing broken files and stutter.

Can friends join a server on my PC without port forwarding?

Yes, with Checkpoint Connect. Players start the game server on their PC and share it with their team. Teammates join through the app, which connects directly when possible or through a relay otherwise, with no router configuration needed.

Is Pro a subscription?

No. Pro is a one-time purchase, bought direct or on Steam, the same as Lifetime. There are no subscriptions on any tier.

What does it cost?

The free plan is real and stays free: 20 MiB, your own space plus one team. Lifetime is a one-time payment — 1 GiB per space, up to 3 teams, bought direct or through Steam. Pro is for big crews: 5 GiB per space, 5 teams, 25 seats each, unlimited read-only share codes. Share codes themselves work on every plan — Free hosts 3 read-only fans at a time, Lifetime 15. No charge per person on any tier.
