Nitter has RSS feeds. I used to use twitter for few years via this way. You can even see account replies via RSS. But, I think nitter has recently disabled RSS feed on main instance https://github.com/zedeus/nitter/issues/986 https://github.com/zedeus/nitter/issues/986. Try to find other instance which support it.
