Meta, the owner of Facebook, is releasing a new app on Thursday that will compete with Twitter.
The app, called Threads, will be connected to Instagram and is currently available for pre-order on the Apple App Store.
Screenshots depict a dashboard that resembles Twitter. Threads is a "text-based conversation app," according to Meta.
Elon Musk, the owner of Twitter, and Meta CEO Mark Zuckerberg have been at odds for some time.
The two men agreed to a physical altercation last month, but it's not clear how serious they were about actually holding one.
In an apparent retaliatory move against Mr. Zuckerberg, Mr. Musk tweeted in response to a tweet about Threads, "Thank goodness they're so sanely run.".
Twitter has announced that TweetDeck, a well-known user dashboard, will become pay-to-use after 30 days.
The move is Mr. Musk's most recent attempt to persuade users to subscribe to Twitter Blue, the company's subscription service.
Due to extreme "data scraping," the multi-billionaire on Saturday limited the number of tweets that users could view.
According to Meta's Threads app, the service will be free and there won't be any limits on how many posts a user can view.
The App Store description for Threads reads, "Threads is where communities come together to discuss everything from the topics you care about today to what'll be trending tomorrow.".
Screenshots from the app are shown in images, and they resemble Twitter almost exactly.
Threads will collect data from your phone, including location information, purchases, and browsing history, as it is a Meta app.
In recent years, a number of applications with striking similarities to Twitter have emerged, including Donald Trump's Truth Social and Mastodon.
Another app of a similar nature, Bluesky, asserted to have observed "record" traffic following Mr. Musk's decision to limit usage over the weekend.
However, Twitter may currently be facing its greatest threat from Threads.
Mark Zuckerberg has a track record of taking ideas from other businesses and implementing them successfully.
Many people believe that Meta's Reels and Stories are imitations of TikTok and SnapChat, respectively.
With its resources, Meta can rival Twitter. There will be hundreds of millions of accounts connected to Threads because it is a component of the Instagram platform. It doesn't start from scratch like other potential competitors have.
Despite receiving praise in some circles for his dedication to free speech, Mr. Musk has also alienated some users.
Mr. Zuckerberg will be hoping to entice enough Twitter users who are dissatisfied to switch to his new service.
