About the project

Upspin is an experimental project to build a framework for naming and sharing files and other data securely, uniformly, and globally: a global name system of sorts.

It is not a file system, but a set of protocols and reference implementations that can be used to join things like file systems and other storage services to the name space.

Performance is not a primary goal. Uniformity and security are.

Upspin is not an official Google product.


Upspin has rough edges, and is not yet suitable for non-technical users.
