There are a bunch of TikTok clones floating around and they've racked up some users. But I'm not sure if these clones would have the tech to serve the kind of recommendations TikTok did. Some, like "Mitron", are basically pre-made scripts bought online and rebadged [0]. They don't have the tech DNA to get recommendations right - which was one big reason for TikTok's success.
