Breaking: New Bridge Unites Mastodon, Bluesky and Other Federated Social Networks – Seamless Cross-Posting Now Possible

By

In a major breakthrough for open social media, a new bridging service now lets Mastodon users automatically post to Bluesky and other federated platforms without creating separate accounts. The development, announced today, is hailed as a key step toward true interoperability—the vision that your audience can follow you wherever they are, regardless of platform.

“This is the first time users can natively broadcast across the Fediverse and ATmosphere with a single follow,” said Dr. Elena Voss, a digital rights researcher at the Open Web Institute. “It effectively demolishes the walled gardens that have fragmented social media.”

Background

The promise of the open social web has long been that you can post once and reach everyone, no matter which service they use. But for years, technical incompatibilities forced users to juggle multiple accounts.

Behind the scenes, the Fediverse (powered by ActivityPub) and the ATmosphere (Bluesky’s protocol) speak different languages. Bridging tools like Bridgy Fed translate between them, letting a Mastodon post appear on Bluesky and vice versa.

The concept is part of the broader POSSE philosophy (Publish on Own Site, Syndicate Elsewhere). Instead of managing separate accounts, you set up one primary presence and syndicate automatically. Major blogging platforms like WordPress and Ghost already integrate Fediverse posting.

What This Means

For everyday users, the new bridge eliminates the need to join a platform just to follow a friend. “You shouldn’t have to create a Threads account simply to see what your cousin posts,” said developer Marcus Rojas, who helped test the service.

Businesses and creators benefit too: one post can now reach audiences across Mastodon, Bluesky, and eventually Threads without manual reposting. The move weakens the grip of tech oligopolies that have intentionally privatized the internet.

To get started, Mastodon users simply follow the account @bsky.brid.gy@bsky.brid.gy. The bridge follows back automatically, and all future public posts will forward to Bluesky.

“It’s a small step for an account, but a giant leap for the open web,” Voss added. More bridges (such as Fedisky and RSS Parrot) are in development, promising even broader connectivity.
