Cross-post to Bluesky, Threads, Mastodon and X in one go
Your audience is split across four networks now. Write the post once in Octopost and send it to all of them together, right now or on a schedule.
Each network has its own rules
Octopost knows each platform's limit. Keep the post under the shortest one, or write it as a thread and each network gets a proper thread.
| Platform | Post length | Long posts become |
|---|---|---|
| Bluesky | 300 characters | Native thread |
| Threads | 500 characters | Native thread |
| Mastodon | 500 characters on most servers | Native thread |
| X (Twitter) | 280 characters on free accounts | Native thread |
| 3,000 characters | Follow-ups as comments |
Questions
What happens when my post is too long for Bluesky?
Write it as a thread. Octopost posts threads natively on Bluesky, Threads, Mastodon and X, so each part lands as a reply to the one before, and the limit applies per part.
Can I post to my own Mastodon server?
Yes. You sign in to your own instance when you connect Mastodon, and Octopost posts to that account.
Can I schedule cross-posts?
Yes. Post now, pick a time, or drop posts into your queue and let Octopost fill your posting slots. Presets save the platform combinations you use most.
How much does it cost?
Basic is $29 a month for 3 accounts, Premium $79 for 10 accounts plus the API and MCP server, Business $199 for unlimited accounts. Every plan starts with a 14-day trial.
