Welcome to Allmydata.org "Tahoe"

Tahoe is a secure, decentralized, fault-tolerant filesystem. All of the source code is available under a choice of two Free Software, Open Source licences. This filesystem is encrypted and spread over multiple peers in such a way that it remains available even when some of the peers are unavailable, malfunctioning, or malicious. The one-page summary explains the unique properties of this system.

Get Started

Live web gateway -- try Tahoe without installing it! (See also the TestGrid Page on the wiki.)

"Install Tahoe" tells how to install it on your own system.

Get Involved

The tahoe-dev mailing list is the community forum. The tahoe-announce mailing list is a low-volume mailing list for announcements.

The Dev page is the place to start hacking on Tahoe.

Documentation
