Hey @sj26 , just wanted to leave a ping here that I've created a 1-to-1 crystal port of mailcatcher that runs as a single binary including assets.

Thanks for this great tool!

Oh and if you want to get rid of some of the dependencies like sass, jquery etc. my repo has vanilla js with no dependencies and plain css you could use.
