websocat

Command-line client for WebSockets, like netcat (or curl) for ws:// with advanced socat-like functions

Runssource: GitHubRustMITcommit 3a3574cd2f5d

Rust, MIT licensed. The project labels itself: cli, command line, command line tool, curl, netcat, proxy, rfc 6455 and socat.

websocat runs. An Argusic agent installed it in 0.5 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.

websocat v1.14.1 builds from source with cargo, passes all 8 tests, and the binary performs WebSocket mirror echo correctly.

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 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.

Replay the whole session, every command from a clean machine to this point.

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 0.5 minutes, faster than the median of the 24 comparable projects Argusic has measured.
  • Nothing broke on the way: zero errors between clone and running.
  • Ran without a GPU, so it does not need one to start.
  • Licensed MIT, as reported by its host.
  • Measured 2 times, so the result is not a one-off.

Of the 25 cli projects Argusic has installed and timed, websocat was the 1st fastest to reach a running state, and 23 of 25 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 0.5 minutes after the clone.
  • Following its own README: the documented path worked with nothing to fix.

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 websocat run?
Yes. websocat runs. Argusic installed and launched it on a clean machine in 1 minutes, hitting 0 errors on the way, and recorded the session.
How did Argusic test websocat?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 3a3574cd2f5d. 2 attempts are recorded, and the full method is on the methodology page.
What did it cost to test websocat?
The run that produced this verdict cost $0.01: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does websocat take to install?
0.5 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 websocat need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing websocat?
Nothing did, in the recorded run: zero errors between clone and running.
How does websocat compare with the alternatives?
Of the 25 cli projects Argusic has installed and timed, websocat was the 1st fastest to reach a running state, and 23 of 25 reached one at all.
Where is the evidence for websocat?
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.
