This is an unofficial twitter client I designed based on chromium. It uses Tweetdeck as its backbone to fetch tweets. Since twitter currently has no official app available to macOS users, this can serve as a perfect alternative while providing great reliability and ease of use.
Some of the key features:
It is completely free with no ads
Uses Chrome WebKit in the backend
Does not utilize the GPU
Supports browsing external links without opening the browser
No window frame, so the browsing experience is distraction-free
