About

Bluestodon

Read full description

Bluestodon is a posting utility for Bluesky and Mastodon. It is not a timeline reader or social client - it has no feed, browsing, following, or notifications. Instead, Bluestodon helps you compose longer posts, split them into threads automatically, preview how they will look on each platform, and post to both services at once. # Write once, post everywhere Type once in a single composer and post to Bluesky, Mastodon, or both at the same time. Bluestodon automatically handles the different platform limits and thread structure for you. # Automatic thread splitting Long posts are split into clean threads independently for each platform. Bluesky and Mastodon use different character limits, so Bluestodon adapts automatically and shows the resulting thread live before posting. Force manual splits anywhere with `---`. # Live dual preview Preview the final thread side by side: β€’ Bluesky preview β€’ Mastodon preview β€’ Character usage gauges β€’ Post counts β€’ Media preview cards See the exact output before sending. # Platform-specific tools Adjust posts per platform: β€’ Text replacements and substitutions β€’ Pinned replacements per account β€’ Per-account defaults β€’ Reply threading β€’ Quote posts β€’ Mastodon content warnings β€’ Mastodon visibility options β€’ Link preview cards for Bluesky # Media support Attach: β€’ Images with alt text β€’ Animated GIFs β€’ Videos β€’ Link preview cards Import by picker, drag & drop, or paste directly into the editor. # Utilities β€’ Drafts β€’ Export thread as text β€’ Activity statistics β€’ Credential validation β€’ iCloud account sync β€’ Multiple accounts Bluestodon is built for people who regularly publish longer posts and threads across Bluesky and Mastodon.
