How to Cross-Post from Threads to Bluesky Automatically
Post natively on Threads 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 Threads to Bluesky
Threads and Bluesky reach genuinely different audiences. Threads is meta-owned and bootstrapped from Instagram — strong on lifestyle, sports, pop-culture, and creator-economy conversation. 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 Threads, 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 Threads 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 | Threads | Bluesky |
|---|---|---|
| Character limit | 500 | 300 |
| Images per post | 10 | 4 |
| Alt text on images | Yes | Yes |
| Video support | Up to 5:00 | Up to 3:00 |
| Native threading | Yes | Yes |
Threads allows up to 500 characters per post, while Bluesky caps each post at 300. When a Threads post is too long for Bluesky, Ferryman automatically splits it into a native Bluesky thread that reads naturally.
Bluesky supports 4 images per post — 6 fewer than Threads. 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.

Edge cases worth knowing
- Skip a specific post: include
#noferryanywhere in your Threads post and Ferryman won't sync it to Bluesky. - Replies and quote posts: off by default. You can enable them in Settings if you want your Threads conversations to appear on Bluesky too.
- Threads on Threads: Threads threads are reconstructed as native Bluesky threads.
- Editing or deleting: Ferryman doesn't propagate edits or deletions automatically. Each platform keeps its own copy once posted.
