FinCat is a plugin for the Cheshire Cat that lets retrive some information about ETFs. You just need to provide the cat with an ISIN or a Ticker and it will search from the ones that are available on JustETF. You can also ask it to look for similar ones based on the same index (see video below).
In the GIF above you can see that I specified a couple of ISINs (I could've used also their tickers) and it provided some basic info.
