Hi HelpfulDeer76 ,
If your experiments use uncommitted changes, these will show up when you compare experiments (and you can see the differences).
Otherwise, the ClearML Server/WebApp has no access to your source code as it's stored in a source control repository (git)

SuccessfulKoala55 Thanks for the clarification. What if I'm not using a git repo, and the script is only stored on a remote server? Is there a way to upload a "snapshot" of it?

If your script is stored in a remote server, how do you execute it? When ClearML is used in a stand-alone Python script, the scripts' content will be stored in the Uncommitted Changes section of the experiment (so comparison should work)
