ebiten
A dead simple 2D game engine for Go
Runssource: GitHubhomepageGoApache-2.0commit 38f48794dd74
Go, Apache-2.0 licensed. The project labels itself: ebiten, ebitengine, game, game 2d, game development, game engine, game engine 2d and game library.
ebiten runs. An Argusic agent installed it in 11 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Ebitengine v2 builds and all tests pass with Go 1.27.1 on Ubuntu 24.04 x86_64 using software-rendered OpenGL and an ALSA null audio PCM device
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.
- TestPrograms/issue2737.go failed: panic due to no audio device (PulseAudio missing, ALSA no cards)5 minutes
- Go binary not found in container (no go version)1 minute
- Install time
- 11 minutes
- Cold machine to finish
- 11 minutes
- Errors hit and fixed
- 2 hit, 2 fixed with no human help
- How the result was proved
- go test ./... with go clean -testcache exited 0: all 52 packages passed, 0 failures
- Model tokens used

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 attempt that decided the verdict above. 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.

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 11 minutes.
- Recovered from all 2 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.
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/ebiten)Questions
- Does ebiten run?
- Yes. ebiten runs. Argusic installed and launched it on a clean machine in 11 minutes, hitting 2 errors on the way, and recorded the session.
- How did Argusic test ebiten?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 38f48794dd74. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test ebiten?
- The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does ebiten take to install?
- 11 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 ebiten need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing ebiten?
- 2 things broke in the recorded run, and 2 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for ebiten?
- 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.
