Zerobyte
A self-hosted Backup, Sync & Storage app you can run on your own server.
Zerobyte is a self-hosted backup, sync and storage tool that you run on your own server instead of renting it as a cloud service. Running it yourself keeps the data on your own network and lets you back it up however you like.
The project is developed in the open via GitHub, where it has earned 6.9K stars from the community. Repository activity was last recorded on Sep 11, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Backup tools must be tested with a restore, not just a successful backup message. Run a trial recovery of one folder, verify checksums or snapshots, and store at least one copy off-site. Sync tools deserve the same care: test conflict behaviour with a throwaway file first.
Like every project listed on SelfHosted, Zerobyte is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
