Well, I wish you the best with this - but I really don't understand the target market.

The obvious competitor here is Tailscale. But let's say, reasons, and Tailscale isn't an option. Then you go down the path... TwinGate, Teleport, Netbird, Pomerium, Netmaker, ZeroTier, etc...

Even the initial pricing and free tier are you're up against are going to mostly be a deal breaker compared to what's out there.

Trusting a VPN provider is a lot. If you're running the control plane - why should I trust Netrinos?

"After years of SSH tunnels, IPsec headaches, and the ssh log horror movie, I wanted something simpler: install, sign in, get work done."

"Target market" could be the author

There's no good reason to discourage people from writing overlays, unless one is doing so for commercial (i.e., anti-competitive) reasons

A more interesting question might be, "In your opinion, what is unsatisfactory about XYZ that does essentially the same thing"

For example, one might be a Layer 2 overlay whilst the other is Layer 3

Maybe we'll never have web browser diversity (or meaningful competition) as the web browser has become an instrument of surveillance and advertising controlled by "Big Tech", but overlay diversity (and competition) is still a possibility

If everyone thought IPsec and OpenVPN was "good enough" then Wireguard and Tailscale would not exist

I still use an unpopular non-commercial L2 overlay from before Wireguard existed that is smaller and faster than anything else I have ever seen

IMHO, the more overlays that exist, the better

Isn’t that true for any new service out there? What’s the market for a search engine? And yet kagi.com is a thing.

Kind of confusing to expect zero competition for a valid opportunity, then you're a category founder with an uphill battle to educate the customer for free, fail, and let the next co swoop in.
