graphhopper runs. An Argusic agent installed it in 37 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
GraphHopper 12.0-SNAPSHOT builds from source, all tests pass (0 failures), and the web server serves valid car/foot/bike routes on port 8989 using the bundled Andorra OSM data.
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).
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.
- No JDK installed, project targets Java 255 minutes
- Initial JDK 21 doesn't support targeting release 252 minutes
- No Maven installed1 minute
- Install time
- 37 minutes
- Cold machine to finish
- 37 minutes
- Errors hit and fixed
- 3 hit, 3 fixed with no human help
- How the result was proved
- curl http://localhost:8989/health returned HTTP 200; curl '/route?profile=car&point=42.5,1.5&point=42.55,1.6' returned HTTP 200 with a 12km route; mvn test BUILD SUCCESS

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.
- Installed in 37 minutes.
- Recovered from all 3 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.
What did not, or is not known
- 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.

[](https://argusic.com/subject/graphhopper)Questions
- Does graphhopper run?
- Yes. graphhopper runs. Argusic installed and launched it on a clean machine in 37 minutes, hitting 3 errors on the way, and recorded the session.
- How did Argusic test graphhopper?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit c1a6369ee4ed. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test graphhopper?
- The run that produced this verdict cost $0.13: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does graphhopper take to install?
- 37 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 graphhopper need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing graphhopper?
- 3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for graphhopper?
- 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.
