C4T free concept simulator
Git Collaboration Concept Simulator
Explore course concepts through adjustable values, prediction, deterministic feedback, and an explanatory trace.
This free concept simulator supports guided prediction, comparison, and reflection. It does not execute code, train models, run databases, create repositories, or replace full project software. The course's always-free pathway also explains how to create project files with freely installable or open tools; paid services and physical hardware remain optional.

1 · Predict
What result will this modeled branch situation produce when the feature is merged?
2 · Explore
Commits made after the feature branch was created.
The changes waiting to be merged.
0 = unrelated content, 1 = different parts of one file, 2 = different edits to the same lines.
3 · Inspect the result
Ready to simulate
Choose a prediction, adjust the controls, and run the lab. The displayed result comes from the simplified values and rules on this page.
