On Friday, the Supreme Court heard arguments in the case that will decide TikTok’s fate in the United States. While some users and developers are hoping that the ban won’t come into effect and they can continue to use the app, judges appear ready to uphold the law that could slowly override it.

As the court’s decision approaches, some of the platform’s approximately 170 million users in the United States are wondering: Where does everyone go instead?

There have been some rumors about Lemon8, a highly visual social media app that focuses primarily on lifestyle content and shares the same Chinese owner as TikTok, ByteDance. Similar to a mix of Instagram and Pinterest, Lemon8 was first launched in Japan in 2020 and has gradually been rolled out to other countries.

In 2023, as lawmakers in Washington criticized TikTok’s chief executive, ByteDance quietly pushed creators to join Lemon8 and offered potential paid incentives. However, due to its ownership, the platform could be subject to the same law as TikTok.

If Lemon8 were also banned, TikTok users would be largely limited to long-established social media platforms like Instagram and YouTube, which have added new features in recent years to compete with TikTok.

Instagram, for example, launched its vertical video feature Reels in 2020 as a response to the ByteDance-owned platform. Initially, some users found Reels to be lacking, but its vertical video format is visually similar to TikTok, and some users are already posting TikTok content there.

In the same year, YouTube introduced YouTube Shorts, which allows short videos of up to one minute.

And of course there is the traditional YouTube video format. In recent years, TikTok has placed an emphasis on longer videos, meaning creators and users alike could be primed to create and watch video content that seems more at home on YouTube than YouTube Shorts.

Yumna Jawad, a recipe developer and content creator who goes by the name Feel Good Foodie, said she feels prepared for the potential ban because she has made sure to never rely too heavily on a single platform in her work.

“I was on Flipboard. I’m trying to figure out Lemon8 and Threads,” said Ms. Jawad, who is 42 and lives in Grand Rapids, Michigan. “There’s always something new and I’m always open to trying things.”
