Went to the page, clicked one that looked interesting called "Wrangler" (I am not familiar with this). No reviews, ok, but not even a link to the owners page? No links to documentation or anything to help me find the original project? Searching for "wrangler" on google helps me find a lot of information about Jeeps. More context would be very helpful.
Searching for "heroku wrangler" would be wiser, and produces a number-one result suggesting that it's a report generation tool for your database: https://devcenter.heroku.com/articles/wrangler
