What Is the Main Problem When Running Multiple Claude Code Instances?
Learn why file editing conflicts are the biggest challenge when running multiple Claude Code instances on the same project and how to manage concurrent editing.
Question
You want to run multiple Claude instances at the same time on the same project. What’s the main problem you need to solve?
A. You can only run one Claude instance at a time
B. Claude instances will run too slowly
C. Claude instances will use too much memory
D. Claude instances will conflict when editing the same files
Answer
D. Claude instances will conflict when editing the same files
Explanation
The primary challenge when running multiple Claude Code instances simultaneously on the same project is file editing conflicts, where different instances attempt to modify the same files concurrently. This leads to race conditions, merge conflicts, corrupted code, or overwritten changes, as there’s no built-in coordination mechanism between instances to prevent simultaneous writes to shared files.
