Peergos - your private online space

Peergos is building the next web - the private web, where end users are in control. Imagine web apps being secure by default and unable to track you. Imagine being able to control exactly what personal data each web app can see. Imagine never having to log in to an app ever again. You own your data and decide where it is stored and who can see it. At Peergos, we believe that privacy is a fundamental human right and we want to make it easy for everyone to interact online in ways that respect this right.

The foundation of Peergos is a peer-to-peer encrypted global filesystem with fine-grained access control designed to be resistant to surveillance of data content or friendship graphs. It will have a secure messenger, with optional interoperability with email, and a totally private and secure social network, where users are in control of who sees what (executed cryptographically). Our motto at Peergos is, "Control your data, control your destiny."

The name Peergos comes from the Greek word Πύργος (Pyrgos), which means stronghold or tower, but phonetically spelt with the nice connection to being peer-to-peer. It is pronounced peer-goss, as in gossip.

For a less technical introduction see, or to dive right into the source code, see github.

WARNING: Peergos has had an audit by Cure53, but is still in active development. Some of the features in this documentation are yet to be implemented, in particular, onion routing is not used yet.


  • Securely and privately store files in a peer to peer network which has no central node and is generally difficult to disrupt or surveil
  • Secure sharing of such files with other users of the network without visible meta-data (who shares with who)

  • Beautiful user interface that any computer or mobile user can understand
  • Secure messaging, with optional interop with actual email
  • Independent of the central SSL CA trust architecture, and the domain name system
  • Self hostable - A user should be able to easily run Peergos on a machine in their home and get their own Peergos storage space, and social communication platform from it
  • Allow users to run web apps within Peergos (and served directly from Peergos) which are totally sandboxed and unable to track users or exfiltrate data
  • Secure web interface as well as desktop clients, native folder sync, and a command line interface
  • Do not rely on any cryptocurrency
  • Enable users to collaborate, editing a document in place concurrently
  • Secure real time chat, and video conferencing able to handle 100s of participants, fully end-to-end encrypted
