Runs itself
Automatic backup
Protect folders on your Mac, external drives, and NAS. SpaceMachine uploads only changes and confirms the result.
Protect your Mac in minutes
Everything important. Protected.
We built SpaceMachine around a simple belief: a backup company should never be able to read your files. Protection runs autonomously, files stay in place even when offloaded, and data is end-to-end encrypted and fragmented across decentralized storage. One private recovery phrase can restore everything you protected on a new Mac. Protection costs around 10× less than traditional cloud storage.

Why SpaceMachine
Your files should stay yours.
Their privacy should not depend on trusting one company, and protection should not require constant attention. SpaceMachine was built around those beliefs: autonomous protection, in-place offload, uncompromised privacy, dramatically lower cost, and recovery from one private phrase.
Core features
One app. Three jobs. Almost no management.
Back up, free space, and recover from the folders you already use.
Paths stay
Offload in place
Free disk space without moving folders into a special storage directory.
Dated history
Restore any version
Recover one file, a folder, or a complete dated backup whenever you need it.
Keys stay with you
E2E, then split apart
Files are end-to-end encrypted on your Mac, then split into coded fragments across independent hosts. No single host receives a readable file.
Write down once
Recovery words
SpaceMachine gives you one private list of words, called your seed. Write it down once to recover everything on a replacement Mac.
Set and forget
Safe autonomy
Set it once. SpaceMachine resumes after sleep, maintains storage, and asks only when your attention is needed.
A simple example
Free 100 GB without changing how you use your Mac.
Offload media or archives you rarely open. SpaceMachine frees the disk space while every item remains visible in its original Finder location.

Pay only for what you protect.
There is no storage plan to buy. The current efficient-storage estimate starts around $0.11 per 100 GB each month with 1.5× Saver redundancy, or about $1.13 per TB.

What 1.5×, 2×, and 3× mean
1.5× stores roughly one and a half copies of your original data for redundancy. 2× means two copies; 3× means three. A longer durability percentage means a lower chance of loss.

Estimated from fluctuating Web3 storage prices and the selected redundancy. Rates can change; restores may add a small, typically insignificant one-time transfer cost. Durability figures are projections, not guarantees.
