I found a Github repo for getting RSS feeds for TikTok users using Github Pages, where you fork it, change Github page url, and add whichever users you want. I was super pumped I found it and excited to use it. After about a week or so though, I've noticed that I wasn't getting any posts for the pretty active TikTok users I added. I looked at the original repository, went to the issues page, and lo and behold, a TikTok update broke a library that the unofficial API, and by extension the TikTok RSS repo, relied on. 😐
I know this is an older post but I completely understand your frustration, even as someone who has the app downloaded! (I know it's not exactly privacy friendly but the app is much more convenient than the web browser. Maybe BlueStacks could be an option but I'm not sure I want to open BlueStacks when I wanna go on TikTok either...)
I did find this page[0] though and it surprisingly still works. Maybe it'll work for you:
