Welcome to Allmydata "Tahoe"

The ​Allmydata "Tahoe" project is a secure, distributed, fault-tolerant storage grid, available under a free-software license.

You can store files in the grid and retrieve them with a cryptographically generated URI that securely identifies and decrypts that file. You can also organize files with filenames and directories, in the familiar style. The basic idea is that the data in this storage grid is spread over all participating nodes, using an algorithm that can recover the data even if a majority of the nodes are no longer available.

The code is currently functional. It is targeted at hackers who are willing to use a minimal, text-oriented web user interface.

Get Started

DownloadDebianPackages tells how to get prebuilt packages for a Debian-like system (including Ubuntu).

The README file tells how to acquire and build the source code, how to run a node than can upload and download files, how to connect to the public test grid operated by ​Allmydata, Inc., and how to set up your own private grid.

Get Involved

The tahoe-dev mailing list is the community forum for discussion of Tahoe design, implementation, and usage. The Dev page is the place to start hacking on Tahoe.

Latest News

2007-06-29 -- Allmydata Tahoe v0.4 is released!

This version adds encrypted, mutable directories, so that you can organize your files into directories, change the contents of directories, and share your directories with your friends, without thereby sharing your directories with anyone else -- not even with the owners of the servers that host your directories.

Please see the Release Notes.

Other News and Status Information

Please see the News page for news, blogs, and network utilization graphs, and please see the Dev page for buildbot, code coverage, patch browser and other useful development tools.

Documentation

See the Doc page for explanation of how Tahoe works.

License

Tahoe is offered under the GNU General Public License (v2 or later), with the added permission that, if you become obligated to release a derived work under this licence (as per section 2.b), you may delay the fulfillment of this obligation for up to 12 months. Code that you release must be released under this same licence including this added permission.

Test Grid

An experimental public grid is running on Allmydata servers. It is subject to being updated at random times, so compatibility is likely to break without notice. It is currently running v0.3.

After installing the code according to the README, set up a client node with the following files in its base directory:

file name	file contents
introducer.furl	pb://xextf3eap44o3wi27mf7ehiur6wvhzr6@207.7.153.180:56677,127.0.0.1:56677/introducer
