Argusic could not verify that userver runs. Argusic installed and launched it on a clean machine, hitting 0 errors on the way, and recorded the session.

How did Argusic test userver?

On a fresh, disposable machine, with every command recorded and the repository pinned at commit 8a281fb06e15. 2 attempts are recorded, and the full method is on the methodology page.

What did it cost to test userver?

The run that produced this verdict cost $0.01: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.

Does userver need a GPU?

Not to start. Argusic reached a running state on a machine with no GPU.

What goes wrong when installing userver?

Nothing did, in the recorded run: zero errors between clone and running.

Where is the evidence for userver?

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.

Production-ready C++ Asynchronous Framework with rich functionality

Could not verifysource: GitHub homepageC++Apache-2.0commit 8a281fb06e15

C++, Apache-2.0 licensed. The project labels itself: async, asynchronous, coroutines, cplusplus, cplusplus 20, cpp20, database access and framework.

Argusic could not get userver running. An Argusic agent hit no errors on a clean machine with no GPU, and the whole session was recorded.

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 20 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.

Cold machine to finish: 2 minutes
Errors hit and fixed: 0 hit, 0 fixed with no human help
Model tokens used: 8,433
Exact commit tested: 8a281fb06e15
Container image: sha256:cdd920bce783

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.

Install time: the run did not report one
How the result was proved: runs before 2026-09-07 did not record the command used to check the result
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
Whether it works at all: this run verified nothing, so this page makes no claim either way

The end of the recording

The last lines of the terminal session that decided this verdict, exactly as they were recorded.

What would you like me to do? For example:
- Fix a bug or implement a feature
- Investigate an error or test failure
- Review code or answer a question about the framework
- Run or set up a specific service from the examples

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

Nothing broke on the way: zero errors between clone and running.
Licensed Apache-2.0, as reported by its host.
Measured 2 times, so the result is not a one-off.

What did not, or is not known

An agent with no time limit did not get it running.

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.
