plexo runs. An Argusic agent installed it in 4 minutes and hit 6 errors on a clean machine with no GPU, and the whole session was recorded.
Plexo installs and builds cleanly; the Electron app launches on the virtual display; the full Playwright suite runs with 284 passing, 20 environment-skips, and no deterministic failures after fixes were applied.
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 96.7 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.

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
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
- `chrome-sandbox` SUID error — fix: `ELECTRON_DISABLE_SANDBOX=1`. - downloads-page `#panel-linux summary not visible` — fix: select Linux tab first. - schedule calendar `Go to the next month` unstable — fix: keyboard activation. - `moved or deleted` rendering only when `isFinished(item)` — fix: use `'missing' in item`. - moved-file right-click menu race — fix: branch on whether the menu still offers Show in folder. **Final verified state** - `npm run typecheck` OK; `npx electron --version` → `v44.4.4`. - Targeted suite: 67/67 passed across the 4 previously-failing files. - Full suite: 284 passed, 20 skipped (all 20 are documented environment/feature exclusions: 17 LAN-… - Smoke suite: 83 passed, 17 skipped. - One non-deterministic timing flake (hedge 2 KB/s race) reproduced 0/18 standalone, 1/284 in a par… **Result line**
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 4 minutes.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Hit 6 errors during setup, 1 of which were not solved.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
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 4 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.

[](https://argusic.com/subject/plexo)Questions
- Does plexo run?
- Yes. plexo runs. Argusic installed and launched it on a clean machine in 4 minutes, hitting 6 errors on the way, and recorded the session.
- How did Argusic test plexo?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 5366a8c01c68. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test plexo?
- The run that produced this verdict cost $1.38: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does plexo take to install?
- 4 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 plexo need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing plexo?
- 6 things broke in the recorded run, and 5 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for plexo?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
