Created a simple revision limiter for WordPress since a lot of similar plugins were behind paywalls. It deletes old revisions based on the limit set and limits future revisions from exceeding the limit. If a post/page revision exceeds the limit, it will delete the oldest revision.
Just drag the folder into your plugin folder. (htdocs > wp-content > plugins)
Works with Gutenburg blocks and Visual Composer (so far with testing). Will have to further test other builders.
Please backup your WordPress instance before deleting revisions, as it cannot be recoverable. I am not responsible for any loss of data.
