Threads' forthcoming compatibility with the open social networking protocol, ActivityPub (the open social networking protocol established by the World Wide Web Consortium), will significantly enhance its interoperability with other applications that support ActivityPub such as Mastodon, and WordPress. This move aims to foster new connections that are currently not achievable in the conventional social app landscape.
Meta stated the following: "Our vision is that people using compatible apps will be able to follow and interact with people on Threads without having a Threads account, and vice versa, ushering in a new era of diverse and interconnected networks."
