How Varsto compares
Tools for keeping files in sync fall into three groups. Peer-to-peer tools such as Syncthing and Resilio Sync copy folders between your own devices. Encrypted clouds such as MEGA, Filen and Tresorit keep your files with one provider. git-annex tracks large files across any disks and remotes you own. Varsto combines parts of all three: end-to-end encrypted files on storages you choose, peer-to-peer transfer between your devices, and a record of where every copy is.

"One provider copy" means the off-site copy is with that provider; your devices keep their own copies too. Each comparison page explains the details and links to the sources.

Varsto is alpha software: do not trust it with data you have no other copy of, and its cryptography has not been independently audited. The other products here are mature. Facts about them were checked from their own documentation in October 2026; prices and plans change often, so see their own pages for current figures.
