ratatui
A Rust crate for cooking up terminal user interfaces (TUIs) 👨🍳🐀 https://ratatui.rs
Runssource: GitHubhomepageRustMITcommit a0189ae4af65
Rust, MIT licensed. The project labels itself: cli, ratatui, rust, terminal, terminal user interface, tui and widgets.
ratatui runs. An Argusic agent installed it in 8 minutes and hit 1 error and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
The Ratatui workspace builds cleanly and all 3176 tests pass on Rust 1.98.1 (stable); interactive examples require a real TTY which is unavailable 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.
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

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.
- Recovered from all 1 error 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 MIT, as reported by its host.
- Measured 3 times, so the result is not a one-off.
What did not, or is not known
- Took 8 minutes to install, slower than the median of the 24 comparable projects Argusic has measured.
Of the 25 cli projects Argusic has installed and timed, ratatui was the 16th 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 8 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/ratatui)Questions
- Does ratatui run?
- Yes. ratatui runs. Argusic installed and launched it on a clean machine in 8 minutes, hitting 1 error on the way, and recorded the session.
- How did Argusic test ratatui?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit a0189ae4af65. 3 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test ratatui?
- The run that produced this verdict cost $0.03: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does ratatui take to install?
- 8 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 ratatui need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing ratatui?
- 1 thing broke in the recorded run, and 1 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does ratatui compare with the alternatives?
- Of the 25 cli projects Argusic has installed and timed, ratatui was the 16th fastest to reach a running state, and 23 of 25 reached one at all.
- Where is the evidence for ratatui?
- All 3 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.
