Control your data.
Control your destiny.
Post-quantum end-to-end encrypted storage, sharing and sync. Not only your files, but their names, their sizes, and who you share them with, stay yours.

Or run the whole thing yourself, for nothing, and still share with everyone else.
Your provider can read more than you think
Encrypting the contents is the easy half. Most services still hold the file names, the folder structure, the sizes and the list of everyone you have ever shared with, which is plenty to work with. Peergos does not hold any of it.
| What a server can see | Peergos | A typical cloud drive |
|---|---|---|
| What is in your files | Hidden | Readable |
| What they are called | Hidden | Readable |
| How your folders are arranged | Hidden | Readable |
| Who you share with | Hidden | Readable |
| Who your contacts are | Hidden | Readable |
A drive, not a website you visit
Sync any folder, in both directions, on as many devices as you like: documents, a music library, the project you are working on. Change one part of a large file and only that part goes up.
On Windows, Linux and Android it mounts as an ordinary drive in your file manager, decrypting as you open things. Calendars and contacts sync to your phone's own apps, and to Thunderbird over CalDAV and CardDAV.
And everything you keep in it
The apps run in a sandbox, on top of the same encrypted storage, and see only the file you opened. Write your own and it gets the same deal.
The drive itself, on any device you log in from
Share with someone, or with a secret link
Send an encrypted follow request to another Peergos user and share with them directly. Nobody, us included, can see who is connected to whom.
For everyone else there are secret links. They work for people who have never heard of Peergos, and the file is still not exposed to the server on the way. Give a link an expiry, a password, a fixed number of uses, or write access.
Sharing uses a hybrid of X25519 and MLKEM-1024, so what you share today is no good to someone who records it now and waits for a quantum computer to catch up.
Open, audited, and not ours to sell
There is no security in obscurity, so all of it is open, the server as well as the client. We have been audited twice, by Radically Open Security and Cure53, and both reports are published in full.
Peergos is a non-profit. No investors, no debt, no advertising, and no free tier that paying customers have to subsidise. What it costs.

This is the most important project right now for the free world, and I want to help it move along faster. A happy customer
Beyond being a happy customer, I genuinely think Peergos is what software should look like. Decentralised, open-source, and independent from Big Tech and VC money. The architecture and philosophy behind it basically tick every box for me.
It’s rare to find a project that stays true to these principles instead of chasing scale or a payout. That’s what drew me in and why I’ve stuck with it.
Huge thanks again to the team for building something that aligns with these values rather than compromising on them.
