Parler (/ˈpɑːrlər/) is an American microblogging and social networking service. It has a significant user base of Donald Trump supporters, conservatives, conspiracy theorists, and far-right extremists. Posts on the service often contain far-right content, antisemitism, and conspiracy theories such as QAnon. Journalists have described Parler as an alt-tech alternative to Twitter, and users include those banned from mainstream social networks or who oppose their moderation policies.
