Bounce launches a service for moving accounts between Bluesky and Mastodon | TechCrunch

"At launch, Bounce can migrate users from Bluesky to Mastodon or Pixelfed, but not the other way around. That's because Bluesky's infrastructure currently only allows users to move off their servers, but doesn't allow migrations back. When that changes, Bounce will launch migration in the opposite direction, too. In addition, early adopters should be aware that once they move their account off of Bluesky, they won't be able to use their Bluesky credentials to log into the app again or other AT Protocol-based services again."

"To work, Bounce uses technology first developed for Bridgy Fed, a tool that connects Mastodon and Bluesky by making users' profiles on one service visible on the other. To move accounts, Bounce first moves a user's Bluesky account to a bridged account that straddles the two networks, then to the user's Mastodon account. This migration also supports Pixelfed, an Instagram-like social app that also runs on ActivityPub, like Mastodon."

Bounce provides cross-protocol migration of follow graphs from Bluesky to ActivityPub networks such as Mastodon and Pixelfed. Bounce uses technology developed for Bridgy Fed to bridge profiles across the two protocols and create a bridged account that straddles both networks during migration. The tool first moves a user's Bluesky account into the bridged account and then into the user's Mastodon or Pixelfed account. At launch Bounce supports only Bluesky-to-ActivityPub migrations because Bluesky's infrastructure currently permits moving off its servers but not migrating back. Users moving off Bluesky will lose the ability to log into AT Protocol-based services with their Bluesky credentials. Bounce was developed by the nonprofit A New Social.
