Honestly, my main use case for Tailscale is my home lab and being able to access my home network devices using a Zero Trust platform that's fully secure. It has been so useful, especially for sharing some of my self-hosted services with family and friends.
For example, I use Tailscale in my home lab by having it installed on all of my devices, like my personal laptop and PC, as well as on my servers. On my servers themselves, let's say I'm hosting a web page on port 3000. I could just use my Tailscale MagicDNS name and then the port, or I could just use the Tailscale IP and the port to access those web pages. So for example, I host things like VIQUINIA and some other things I can easily access. Another use case that I have for Tailscale in my home lab is I have it installed on my firewall, which is built with OPNsense. What I do is I have it set as an exit node and I also broadcast my entire subnet. So that way, it's as if I'm connecting to a regular VPN and have access to my full home network, not just the devices that have Tailscale installed on them. I can also funnel my traffic through my home network if I'm elsewhere. Since I have my own custom DNS set up, if I am using my network as an exit node, I get free ad-blocking wherever I go.
For my organization, we use Tailscale for our database as a secure way to access our VPC. It's really great. It's an easy way for everyone to connect and disconnect. Nothing clunky, nothing being left behind, very lightweight, very nice UI, and very useful. For my home lab, it has been great because there are services you want to host, but you don't want to expose them to the public network, and using Tailscale gives you a very nice way of actually accessing that without having to deal with exposing things to public ports. I also really appreciate Tailscale services, which I forgot to mention, which involves hosting a service on Tailscale itself.
Regarding metrics, I guess a lot of times it saves hours. Sometimes I forget something at home and if I use Tailscale, I can easily access my network and grab it, whereas usually I would have to drive back home. I feel that in itself is really huge.
The best features Tailscale offers are their free tier, which is amazing. Whatever it provides, I feel it's a very good amount for what it gives you. I would honestly even be open to paying if my needs expand from what I am currently using. I feel the Zero Trust networking thing is really great. I feel the ability to also integrate Mullvad VPN into your own Tailscale network and use that as an exit node is huge. It makes a very nice, seamless experience for VPN. Rather than having multiple clients, you just use Tailscale and that handles everything for you. I also appreciate the Tailscale drop feature. I feel that's very unique, kind of a global AirDrop with anything that has Tailscale. So it's a really simplified way of sharing files, not only over your local network, but over your Tailscale network, your virtual cloud.
A unique thing that I did, which at the time was an experimental feature, but now I believe it's fully out and available, is using Tailscale files. Essentially, I had a bunch of space on my server and I made a Tailscale share. So now if I ever go on any of my devices, I have a whole file section which I can actually just drag and drop to that location and it's kind of a shared Google Drive. Any of the old storage I had lying around, I was able to convert it into my own free cloud storage.
I would say I rely on just the regular Tailscale Zero Trust network the most in my daily workflow. I feel I have that on all the time and I'm accessing things when I'm not at home. Usually, when I'm traveling, it's when it's the most useful, but if I'm staying at home and working from home, it's not as useful because I'm connected to my same network. But for example, if I'm at my in-laws' house or if I'm outside at a library or coffee shop, it's very useful to have.
I feel the speed of the control servers are a bit too slow. I feel that's the main bottleneck right now for Tailscale. For example, at my apartment, I can do 2-gig networking, but when I connect via the exit node, and I'm wired in somewhere else, and that place also has 2-gig networking, I'm at max getting half of my speed. The main bottleneck here is really the control servers and the throughput of data.
I feel Linux needs its own UI client. I had to use a custom third-party one. That is a big thing as well.
To make it a 10, I mean, have better support for Linux. That's probably the main thing, honestly. Fix the DNS things too. There's some issues where I should be able to use my own custom DNS easily and then when you move MagicDNS starts causing problems, I should be able to just have my own custom DNS that links directly into Tailscale and assign each thing its own specific hostname. I feel that doesn't work as well as expected, or maybe you do provide that, but then it's kind of obfuscated through weird documentation.
I have been using Tailscale for about two years or a year and a half.
Tailscale's scalability is good.
It has been a really great product. Ever since I started using it, I got my family members to get on it and so many other people, and I very openly recommend it.
I looked at Netbird or something before choosing Tailscale.
I advise others looking into using Tailscale to start faster or look at the documentation.
