Frequently Asked Questions
5 questions
Threads does not offer data export functionality—your account and content remain locked within Meta's infrastructure. Bluesky users can export their full account data including all posts and followers at any time via their account settings, and can migrate to another AT Protocol server while keeping their handle and follower list. This is a fundamental architectural difference: Threads is designed for retention, Bluesky for portability.
