Ditch the dedicated server; your co-op group is probably paying for empty hours
A 24/7 rented box is great when ten people play every night. For the average co-op group, it's $120–$240 a year of idle uptime. Here's the math, and how Checkpoint64 covers ~90% of the use case for a one-time payment.

The Steam launch is going great; what we're building next
A few days in, wishlists are climbing and the playtest is full of strange, wonderful saves. Thank you. A quick note on how it's going and what comes next.

Checkpoint64 is on Steam! Wishlist it and join the playtest
There's now a Checkpoint64 page on Steam. You can wishlist it, follow for the launch, and get into the playtest — and yes, the irony of a save-backup tool living next to Steam Cloud is the whole point. Here's what the listing means and what it doesn't change.
-
Back up the whole folder; the save files your game writes later won't slip through
Picking save files by hand has a blind spot — it never notices the ones your game writes after you set it up. A new farm, a fresh profile, an extra slot. The next build can watch the whole save folder and keep catching whatever lands in it. Restoring got safer too. Here's what's new.
-
Anatomy of a save corruption; what actually happens on disk
Corruption sounds like bad luck, but it's usually one of a handful of very specific things going wrong at the byte level — almost always during the write. Here's what a save file really is, the three ways it gets mangled, and why a single save slot is a single point of failure.
-
The free plan just grew a team; try co-op without a card
Free accounts can now create one team — invite your co-op partner, pass the lock, read the logbook, all without paying. Lifetime quietly went from 2 teams to 3 while we were at it. Here's what changed and why.
-
Cloud saves aren't backups; sync will happily overwrite your good save
Steam Cloud, GOG Galaxy, and console cloud saves keep one copy in sync across your machines. That's not the same as a backup. The moment a save corrupts or a bad autosave fires, sync does its job perfectly and pushes the broken file everywhere. Here's the difference, and why versioning is the thing you actually wanted.
-
The perfect companion for emulators; real version history for save states
Emulators already let you save anywhere. What they don't give you is a history. Checkpoint64 watches the save folder your emulator writes to and turns every save into a versioned, restorable timeline — a rewind button that survives across sessions, machines, and emulator updates.
-
Community servers; host a world, share it with a crowd, keep it pristine
A creator can now host a save and hand out a join code that lets an audience download the world without being able to touch it. No write access, no accidental overwrites, capped and revocable. Here's what read-only members are and when you'd want them.
