Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging, supported on multiple platforms, and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes. Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4. For more information, see our about page.
The project is currently in the alpha stage. You can expect the occasional breaking change and backwards incompatibility, but Yggdrasil is generally stable for day-to-day use.
Yggdrasil is written in Go. The codebase is fairly small and easy to navigate. It has been tested on a number of platforms (including Linux, Windows, macOS, FreeBSD, OpenBSD and Ubiquiti EdgeRouter). See our developers page for more info.
A small number of users have been using and stress-testing Yggdrasil quite heavily for a variety of use cases. We have a number of internal services available, contributed and operated by the community.
