tailscale runs. An Argusic agent installed it in 3.5 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

Tailscale tailscale and tailscaled binaries for Linux amd64 built and report version 1.103.0-dev20260924; 303 unit tests pass in the container.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing tailscale, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load

Watch the session

The whole run, from a clean machine, at the speed it actually happened. Nothing is cut and nothing is sped up.

A recording of attempt 2, run , the attempt that decided the verdict above. The terminal recording it was made from is the evidence, stored with a sha256 fingerprint; the video is a rendering of it. Nothing loads from the video host until you press play.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Reached a running state on a clean machine, with the session recorded.
  • Installed in 3.5 minutes, faster than the median of the 3 comparable projects Argusic has measured.
  • Recovered from all 2 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Ran without a GPU, so it does not need one to start.
  • Licensed BSD-3-Clause, as reported by its host.
  • Measured 2 times, so the result is not a one-off.

Of the 4 2fa projects Argusic has installed and timed, tailscale was the 1st fastest to reach a running state, and 2 of 4 reached one at all.

What it is a reasonable choice for

  • Trying it on a laptop or a small server: it reached a running state without a GPU.
  • A quick evaluation: it was running 3.5 minutes after the clone.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does tailscale run?
Yes. tailscale runs. Argusic installed and launched it on a clean machine in 4 minutes, hitting 2 errors on the way, and recorded the session.
How did Argusic test tailscale?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit d229a06f9a4b. 2 attempts are recorded, and the full method is on the methodology page.
What did it cost to test tailscale?
The run that produced this verdict cost $0.09: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does tailscale take to install?
3.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does tailscale need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing tailscale?
2 things broke in the recorded run, and 2 were fixed without human help. Each one, and the time it cost, is listed on this page.
How does tailscale compare with the alternatives?
Of the 4 2fa projects Argusic has installed and timed, tailscale was the 1st fastest to reach a running state, and 2 of 4 reached one at all.
Where is the evidence for tailscale?
All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
