ZeroTier VS netbird

Tailscale uses Go https://tailscale.com/security#tailscale-is-written-in-go which might explain the larger sizes.

A cursory look through https://github.com/zerotier/ZeroTierOne shows more C++ and some Rust. Not sure how much static linking is involved here.

ZeroTier - Layer 2 overlay network. They take decentralization seriously, and like to say "decentralize until it hurts, then centralize until it works." Written in C++.

EDIT - I'm tired and cross-eyed after a bunch of internet searching and rabbit holes... A supposed ZeroTier dev said on April 25, 2023 that this would be addressed in a future release of the app in this thread: https://github.com/zerotier/ZeroTierOne/issues/1952. On August 10th, another engineer said that they are waiting for a car to be delivered.

If you just want to connect between your devices, you don't need any hardware. Just install zerotier on them.

Recently I've been looking at VPN solutions, specifically ones built around WireGuard, that take away some of the manual steps required to manage a large scale deployment. After building proof of concept solutions with several of these offers, I settled on NetBird.

The project that has a feature which allows admins to SSH to any computer in the VPN ? [1]

They have a feature called remote SSH access where the agent running on the node allows other VPN users to SSH to another machine on the network without having SSH enabled / public keys set up. I've tested the project at the beginning of the year and it was a big NO for me. They seemed to fix this issue but it appeared again.

Or https://netbird.io which is open-source. You can host the coordination server too :)

https://github.com/netbirdio/netbird seems to be completely open source (BSD), https://github.com/gravitl/netmaker?tab=License-1-ov-file#re... uses Apache for the non-pro stuff, and both of those I found by simply looking at https://github.com/topics/wireguard

This is why I asked, the phrase "I decided to reinvent the wheel which has honestly been quite fun with learning about eBPF, and recently clustering and HA with etcd" makes it sound like it's doing a bunch of cool stuff (which I want to hear about!), but the readme says nothing about those.

The best way to securely connect your functions to your other resources is with an encrypted mesh network like NetBird. NetBird lets you link your infrastructure together using a zero-config private WireGuard network that works across cloud, serverless, and on-premise infrastructure.

NetBird - NetBird is an open-source VPN management platform built on top of WireGuard® making it easy to create secure private networks for your organization or home.

NetBird simplifies Kubernetes access with its zero-configuration approach, leveraging WireGuard's simplicity and strength. It seamlessly integrates with various tools, offering transparency and high reliability as an open source solution.
