Bluestodon - Write once, Post everywhere

Bluestodon is a posting utility that lets you write once and automatically post to both Bluesky and Mastodon simultaneously. It intelligently splits long posts according to each platform's character limits (300 for Bluesky, up to 500 for Mastodon), handles platform-specific details like mentions, link cards, and visibility controls, and provides a live side-by-side preview as you compose. Designed for users who regularly post to both decentralized social networks without the friction of manual rewrites.
