You can create more than one codespace per repository or even per branch. However, each user account has a limit of 10 codespaces. If you've reached the limit and want to create a new codespace, you must delete a codespace first.
Note: Only the person who created a codespace can delete it. There is currently no way for organization owners to delete codespaces created within their organization.
Navigate to the "Your Codespaces" page at github.com/codespaces.
To the right of the codespace you want to delete, click , then click Delete
Under "Codespaces", right-click the codespace you want to delete.
In the drop-down menu, click Delete Codespace.
To learn more about GitHub CLI, see "About GitHub CLI."
To delete a codespace use the
gh codespace delete subcommand and then choose a codespace from the list that's displayed.
gh codespace delete
If you have unsaved changes, you'll be prompted to confirm deletion. You can use the
-f flag to force deletion, avoiding this prompt.
For more information about this command, see the GitHub CLI manual.
