How to Crosspost Between X, Farcaster, and Bluesky

Posting the same content across X, Farcaster, and Bluesky manually is tedious. Copy-pasting breaks mentions, threads don't transfer, and media needs reformatting. Here's how to automate it.

The problem with manual cross-posting

Each platform has different character limits, threading formats, mention systems, and media requirements. When you copy-paste a post from X to Farcaster, @mentions break, threads don't convert, and images may not display correctly.

The solution: Crenel crossposting

Crenel solves this with automatic crossposting. Here's how it works:

1. Connect your accounts - Link your X, Farcaster, Bluesky, and/or Mastodon accounts to Crenel.
2. Set your crosspost rules - Pick which platform(s) you post on natively (your "sources") and which ones should receive automatic cross-posts (your "destinations").
3. Post as normal - Post on your source platform as you always do. Crenel detects the new post and automatically publishes adapted versions to your destinations.

What Crenel handles automatically:

• Mention mapping - @tags are translated so the right people get tagged on each platform
• Thread adaptation - Long posts are threaded on platforms that support it (X, Farcaster) and truncated with a link on others
• Media formatting - Images and videos are resized and reformatted for each platform's requirements
• Repost/boost detection - Reposts can be relayed as links rather than duplicating content
• Cross-platform analytics - Engagement over time, top engagers and top posts, and follower growth trends across every connected account

Example setup

Post on Farcaster → Crenel auto-publishes to X, Bluesky, and Mastodon. Or post on X → auto-publish to Farcaster, Bluesky, and Mastodon. Any combination works.
