betteroffice
Native OOXML engines in Rust - DOCX, XLSX & PPTX editing, rendering and real-time collaboration, compiled to WASM for the web.
Runssource: GitHubhomepageRustApache-2.0commit 1af946fc0ef6
Rust, Apache-2.0 licensed. The project labels itself: docx, office suite, ooxml, pptx, rust, spreadsheet, wasm and word processor.
betteroffice runs. An Argusic agent installed it in 35 minutes and hit 8 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Rust engine, WASM modules, all 11 TypeScript/React packages, CLI binaries (xlsx render/info, redact), and collaboration relay work correctly in this container, 806 JS tests, 1400+ Rust tests, and 3 relay E2E tests all pass with zero failures.
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.
- Bun not installed; no root for apt-get5 minutes
- Node.js 18 too old for wrangler (needs >=22)4 minutes
- Rust toolchain not installed3 minutes
- wasm-pack 0.15.0 not installed3 minutes
- wasm-opt not found2 minutes
- Response body already used errors in check-publish-targets.test.ts1 minute
- Install time
- 35 minutes
- Cold machine to finish
- 50 minutes
- Errors hit and fixed
- 8 hit, 8 fixed with no human help
- How the result was proved
- cargo test exited 0 (all 1400+ Rust tests passed); bun test across all packages exited 0 (806 tests passed, 1 skip, 0 fail, 2385+ expect calls); cargo run --bin xlsx -- info sample.xlsx printed correct sheet metadata; cargo run --bin xlsx -- render sample.xlsx produced a valid 500x200px PNG file (verified header + IHDR chunk); cargo run --bin betteroffice-redact -- sample.xlsx redacted 321 text nodes successfully

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 1, run . The verdict above comes from a different attempt, so read this as one session and not as the current result. 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.
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
=== BUN TEST PPTX === Ran 92 tests across 7 files. [1319.00ms] === BUN TEST DOCX-REACT === Ran 154 tests across 25 files. [1244.00ms] === BUN TEST PPTX-REACT === Ran 75 tests across 9 files. [8.59s] === BUN TEST XLSX-REACT === Ran 30 tests across 3 files. [7.31s] I now have the complete picture. Here is the final report: tokens used 152,346 I now have the complete picture. Here is the final report:
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 35 minutes.
- Recovered from all 8 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 Apache-2.0, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
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/betteroffice)Questions
- Does betteroffice run?
- Yes. betteroffice runs. Argusic installed and launched it on a clean machine in 35 minutes, hitting 8 errors on the way, and recorded the session.
- How did Argusic test betteroffice?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 1af946fc0ef6. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test betteroffice?
- The run that produced this verdict cost $0.25: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does betteroffice take to install?
- 35 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 betteroffice need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing betteroffice?
- 8 things broke in the recorded run, and 8 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for betteroffice?
- 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.
