About Ouisync

Ouisync is a private and resilient solution for syncing files and folders with your devices, contacts and groups.

Easy to use

Simply install and quickly create files and folders to sync and share with trusted devices, contacts and/or groups.

Offline-first

Ouisync uses an innovative, synchronous, peer-to-peer design that allows users to access and share files and folders whether or not your device can connect to the internet.

Secure

End-to-end encrypted files and folders - both in transit and at rest - secured by established, state-of-the art protocols.

Free for everyone

No in-app purchases, no subscriptions, no ads, and no tracking!

Access Controls

Create repositories that can be shared as read-write, read-only, or blind (you store files for others, but cannot access them).

Open Source

Ouisync's source code is 100% free and open source software, now and forever. All code can be found on Github.

Status and Roadmap

July 2023: We are soft launching the first stable release of Ouisync this month! Please note that the app is under active development, and as such some features and functionality may not work as expected. We encourage users to report bugs and request new features via Github
