How it works

One post, both networks

Keep your X audience and grow your Bluesky one — without doing everything twice.

1

Connect Bluesky & X

Bluesky connects in one click (or with an App Password). Add X with your own API keys for full posting and media support.

2

Write it once

Compose your post and attach up to four photos or a video. Pick Bluesky, X and any other networks you'd like it on.

3

Post to both

Hit post and Klaxon delivers it to Bluesky and X together, and tells you exactly what landed where.

Why creators love it

Keep a foot in both camps

🤝

No choosing sides

Grow on Bluesky while keeping your X followers in the loop. Every update reaches both from a single box.

🖼️

Photos & video on both

Attach up to four images or a clip and Klaxon handles each network's rules — Bluesky video included (confirmed email required).

↻

Retry only what failed

If X hiccups but Bluesky went through, one tap re-sends just X — your Bluesky post is never duplicated.

🗓️

Schedule to both

Line posts up ahead and Klaxon fires them to Bluesky and X at the time you set.

🌐

And five more networks

Add Threads, TikTok, Instagram, Facebook and YouTube to the same post whenever you want wider reach.

🔒

Your keys, encrypted

You connect your own accounts. Credentials are encrypted at rest and Klaxon only ever uses the official platform APIs.

Questions

Bluesky + X, answered

How do I post to Bluesky and X at the same time?
Connect both accounts to Klaxon, write your post once and tick Bluesky and X (and any other networks you want). Hit post and Klaxon sends it to all of them together — you don't have to post twice.
Can I cross-post to Bluesky and X automatically?
Yes. Every post you write in Klaxon can go to Bluesky and X in one action, so your new posts land on both without copy-pasting. You can also schedule them ahead or auto-announce when you go live on Twitch.
Do I need API keys or an app password?
Bluesky connects in one click, or with your handle and a Bluesky App Password — no developer setup. X needs your own X developer API keys to post media and for higher usage, which you add once in Settings.
Can I post images and video to Bluesky?
Yes — attach up to four images or a short video and Klaxon handles the formats. Bluesky needs a confirmed email address before it accepts video, and keeps clips to around 50 MB.
