# Yggdrasil

24 Hacker News commenters recommended Yggdrasil and 10 criticized it, November 2025 to November 2026. It was recommended in 11 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Recommended as a stable, self-organising IPv6 mesh that runs quietly in the background and works as a Tailscale alternative. Critics note it is not built for anonymity or censorship resistance.

## Why people recommend it

- Stable, runs quietly in background (3 comments): "I've been using it as a Tailscale replacement for a few weeks, including hosting game servers, with about equivalent latency, and it seemed pretty stable." ([source](https://news.ycombinator.com/item?id=46689170)) "It simply runs in the background and does its job so reliably that I simply forget about it for long periods of time." ([source](https://news.ycombinator.com/item?id=46691218)) "Yggdrasil is easier to have always running in the background so I don't have to toggle it on just to access AA." ([source](https://news.ycombinator.com/item?id=46499672))
- Works as Tailscale alternative (3 comments): "I've been using it as a Tailscale replacement for a few weeks, including hosting game servers, with about equivalent latency, and it seemed pretty stable." ([source](https://news.ycombinator.com/item?id=46689170)) "It's been working well for me as a kind of poor-man's tailscale, connecting several VPS and several laptops." ([source](https://news.ycombinator.com/item?id=47619349)) "the public Yggdrasil network was much better than a mesh VPN like Tailscale" ([source](https://news.ycombinator.com/item?id=46698437))
- Self-organising routing, no central authority (4 comments): "It's high-performance, uses regular IPv6 TCP/UDP, and automatically forms one big, open network, where routes are available." ([source](https://news.ycombinator.com/item?id=46696753)) "I like the idea of a network with no central authority delegating addresses." ([source](https://news.ycombinator.com/item?id=47621652)) "I love the idea of a decentralized routing system." ([source](https://news.ycombinator.com/item?id=47621717))
- Fast, low latency (3 comments): "It makes no compromises on speed and latency, but it has no anonymity." ([source](https://news.ycombinator.com/item?id=49875569)) "I'm actually getting better speeds than WireGuard over my LAN" ([source](https://news.ycombinator.com/item?id=45825045)) "It is fast, resilient, and pure IPv6." ([source](https://news.ycombinator.com/item?id=46609955))

## What people warn about

- Not built for anonymity or censorship resistance (2 comments): "It makes no compromises on speed and latency, but it has no anonymity." ([source](https://news.ycombinator.com/item?id=49875569)) "Yggdrasil was never designed to be censorship-resistant and can be blocked with trivial DPI." ([source](https://news.ycombinator.com/item?id=46612643))
- Needs tun/tap setup, more work (2 comments): "Yggdrasil-go needs a tun/tap interface" ([source](https://news.ycombinator.com/item?id=47486744)) "So it's more work to set up." ([source](https://news.ycombinator.com/item?id=47623211))
