LaunchStack runs. An Argusic agent installed it in 45 minutes and hit 5 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
LaunchStack monorepo installs cleanly after Node upgrade to v20.11.0; package-level vitest (327/327) and web jest (hundreds of unit+integration tests) all pass against a standalone PostgreSQL 16 with pgvector; only missing real external credentials for chat, S3, and provider APIs.
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 90 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
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.
- PostgreSQL not available (README expects Docker Compose)8 minutes
- Node v18.19.1 below required ≥202 minutes
- pnpm not installed1 minute
- rollup-linux-x64-gnu native optional dependency missing1 minute
- Jest setup did not load .env so integration tests skipped1 minute
- Install time
- 45 minutes
- Cold machine to finish
- 33 minutes
- Errors hit and fixed
- 5 hit, 5 fixed with no human help
- How the result was proved
- pnpm install exited 0; package vitest: 327 passed/21 skipped; web jest (non-integration): 574 passed/1 skipped across 66 suites; web jest (integration with live Postgres): 192 passed across 23 suites; DB migrations: 22 applied (4 engine + 18 product); seed: 1 company/1 user/1 document; typecheck: all packages passed

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.

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 45 minutes.
- Recovered from all 5 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/launchstack)Questions
- Does LaunchStack run?
- Yes. LaunchStack runs. Argusic installed and launched it on a clean machine in 45 minutes, hitting 5 errors on the way, and recorded the session.
- How did Argusic test LaunchStack?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit a2fb47de0aae. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test LaunchStack?
- The run that produced this verdict cost $0.19: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does LaunchStack take to install?
- 45 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 LaunchStack need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing LaunchStack?
- 5 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 LaunchStack?
- 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.
