What is Peergos?

Peergos is an end-to-end encrypted global filesystem that runs over a peer-to-peer network built on IPFS. Files are split into 5 MiB chunks and encrypted on the user's device, and servers cannot see file contents, sizes or who shares with whom. On top of the filesystem sit a secure messenger, an encrypted email client and bridge, a private social network and sandboxed HTML5 apps that run with permissions the user grants. You can log in from any machine with just a username and password, because keys are derived with scrypt. The server runs on the JVM and is mostly written in Java.

Good fit if

  • You want cloud-style file storage where even a compromised server cannot read your data or metadata.
  • You share files with friends and want the sharing graph itself kept hidden.
  • You are comfortable running a Java server at home, or prefer paying for the project's hosted service.

Look elsewhere if

  • You want a conventional self-hosted file cloud without a peer-to-peer layer: Nextcloud.
  • You only want to keep folders in sync between your own devices: Syncthing.

Before you adopt it

Peergos is licensed under AGPL-3.0; it switched from GPL-3.0 to AGPL-3.0 in September 2015. The repository has no paid parts, though the team runs a paid server at peergos.net and accepts donations. The README links security audits from 2019 and 2024. There is no Docker image, compose file or tagged release, so setup means building and running the Java server yourself. Two authors made all commits in the last 90 days, with one responsible for about two thirds. The project does not provide anonymity on its own; the README suggests using Tor for that.

Read from GitHub on 12 November 2026. How the score works

Peergos security

Security advisories are the vulnerabilities the maintainers disclosed on GitHub, with the versions that fix them; many advisories can mean careful disclosure as much as weak code. OpenSSF Scorecard checks how a project is developed and released: reviews, protected branches, pinned dependencies, signed releases. It does not audit the code itself.
