https://ibboard.co.uk/cawbird/ - https://github.com/IBBoard/cawbird
its a twitter client, fork of corebird that was previously in the repos, there are no alternatives that i know of, except the web client which is horrible imo
open source, GPL3
Despite it fundamentally not making substantial improvements upon Corebird, nor has any magical functionality to regain real-time streams of tweets (since Twitter nuked that API for third-parties), going to accept for inclusion since we really really need a proper native Twitter client.
I agree, the web client is an abomination. Typically I've used Tweetdeck instead.
