With a possible TikTok ban just days away, many U.S. users are looking for alternative social media platforms to help them keep up with pop culture or provide the type of entertaining videos that popularized the short-form video app.

TikTok, which has been a cultural phenomenon, could be banned on Jan. 19 under a law that forces the platform to cut ties with its China-based parent company, ByteDance, or shut down its U.S. operation.

The fate of social media platform will be decided by the Supreme Court, which last week heard oral arguments in a legal challenge to the statute and seemed likely to uphold the law. The court could rule on the case as soon as this week. Meanwhile, President-elect Donald Trump has asked the justices to put the law on hold so he can negotiate a "political resolution" to the issue after he takes office.

TikTok has more than 170 million users in the U.S., and if it does get banned, it's not clear which competitors will benefit the most. Some experts think established social media platforms, such as Instagram and YouTube, could see the biggest influx of users. But some users are looking for something different and could turn to other apps.

Here are the different alternatives and what to know about them:

Recently, some U.S. TikTok users have flocked to the Chinese social media app Xiaohongshu in protest of the looming ban. Like TikTok, Xiaohongshu, which in English means "Little Red Book," combines e-commerce and short-form videos.

The app has gained traction in China and other regions with a Chinese diaspora -- such as Malaysia and Taiwan -- racking up 300 million monthly active users, a majority of whom are young women who use it as a de-facto search engine for product, travel and restaurant recommendations, as well as makeup and skincare tutorials.

On Tuesday, the Xiaohongshu, called "RedNote" by American users and on some app stores, was the top downloaded free app in Apple's U.S. app store.

Lemon8, also owned by TikTok's parent company ByteDance, is a lesser-known lifestyle app that allows users to post pictures and short-form videos. Though the platform lets users post TikTok-like videos, it leans more into pictures and has been described as a mixture of Instagram and Pinterest.

In the past few weeks, many creators have hailed Lemon8 as the place to go if TikTok is banned under federal law. Some have also recommended it through paid sponsored posts tagged #lemon8partner, indicating a recent corporate push to generate more users.

But the law that targets TikTok also states the divest-or-ban requirement for ByteDance applies generally to apps that are owned or operated by the two companies or any of their subsidiaries. That means even though Lemon8 is not explicitly named in the statute, its future in the U.S. is also in jeopardy.

Instagram launched Reels in 2020, a TikTok-like feed of short videos users can create or scroll through. The feature has proven to be massively popular and some experts say creators are likely to set up shop there if a TikTok ban does happen. As of 2022, Instagram had 2 billion active monthly users. Meta no longer discloses user numbers for its individual platforms.

But could it replace TikTok? That depends. While many creators currently post on both platforms, some experts say the youngest users are unlikely to migrate to a service made popular by their millennial parents. And while Meta's algorithm is addictive, it's still not TikTok.

In the past, some TikTok users have also blamed the surge of scrutiny on the platform on Meta CEO Mark Zuckerberg, pointing to a Washington Post report from 2022 that said the tech behemoth paid a Republican consulting firm to undermine TikTok through a nationwide media and lobbying campaign.

Though TikTok dominates headlines as a driver of internet trends, Pew Research Center says YouTube is actually the most widely-used platform among teens and adults.

YouTube users can scroll through Shorts just as they can on TikTok or Reels on Instagram and Facebook, allowing them to watch hours of bite-sized videos. Many of the videos featured on YouTube are from TikTok or creators who post to several platforms. That said, YouTube is still known for its longer-format videos so it may not have the variety of content that TikTok users are looking for -- at least not yet.

Snapchat, launched in 2011 with its infamous disappearing videos, remains popular among teens and younger adults. The platform gained so much traction that Meta designed a similar feature in Facebook and Instagram called "Stories" that lets users post photos or videos that disappear within 24 hours. In 2020, Snapchat launched another feature that lets users "shine a light on the most entertaining Snaps, no matter who created them."

The platform is estimated to have roughly 692 million global monthly active users last year, according to eMarketer.

For TikTok users who enjoy the "TikTok Live" feed that features livestreamed videos, Twitch could be a good alternative. The Amazon-owned platform is a leader in the streaming industry and allows users on the platform to watch some of the internet's most popular streamers, such as Kai Cenat. Twitch is estimated by eMarketer to have over 36 million users.

Clapper, a TikTok clone, has also been gaining some traction amid the looming ban. The app was launched in 2020 by Dallas-based entrepreneur Edison Chen, and focuses on Gen X and millennial users. In September of that year, the company described itself in a Facebook post as a "free speech" platform that did not "censor posts and comments." But in blog post on its website from 2021, the company wrote it "stopped being a 'Free Speech' platform" in September 2020 and "changed its mission and goals" to focus on "community".

For TikTok users who want to get away from the overcrowded spots, there are lesser-known apps like Triller, which is popular for music videos, and Zigazoo, which was designed with kids in mind.

If none of these apps tickle your fancy, it's also possible that other platforms could emerge in the next few months as companies attempt to attract users looking for a new place to go.
