How to Cross-Post from Facebook to Bluesky Automatically
Post natively on Facebook and Ferryman automatically syncs every new post to Bluesky — no copy-paste, no workflow change. Set up in under two minutes.
Why cross-post from Facebook to Bluesky
Facebook and Bluesky reach genuinely different audiences. Facebook is the broadest reach of any social platform — Pages put your content in front of a general, multi-generational audience. Bluesky, by contrast, is tech, open-source, journalism, and a fast-growing community of X expats who want chronological feeds and open protocols.
One of the fastest-growing social platforms — every wave of X frustration sends a new cohort of creators here. If you're already putting in the effort to write good posts on Facebook, there's no reason that work shouldn't reach a Bluesky audience too — except that maintaining two presences manually is exhausting and easy to abandon. That's the problem Ferryman exists to solve.
Key differences between Facebook and Bluesky
Cross-posting isn't just a copy-paste. The two platforms have different limits and conventions, and Ferryman handles each difference so you don't have to think about it.
| Capability | Bluesky | |
|---|---|---|
| Character limit | 63,206 | 300 |
| Images per post | 30 | 4 |
| Alt text on images | No | Yes |
| Video support | Up to 10:00 | Up to 3:00 |
| Native threading | No | Yes |
Facebook allows up to 63,206 characters per post, while Bluesky caps each post at 300. When a Facebook post is too long for Bluesky, Ferryman automatically splits it into a native Bluesky thread that reads naturally.
Bluesky supports 4 images per post — 26 fewer than Facebook. If you post more images than Bluesky allows, Ferryman includes the first 4 on Bluesky and notes the overflow in your dashboard.
Videos longer than 180 seconds exceed Bluesky's cap. Ferryman handles the length difference so the rest of your cross-post still goes through.
What gets synced

Edge cases worth knowing
