Questions
- Is this Bluesky post preview free?
- Yes. There is no login and no upload: it runs entirely in your browser, and nothing you type or attach leaves your device.
- Does the preview match what Bluesky actually shows?
- It is the same chrome our studio uses before a post publishes: Bluesky's current header layout, action row and media grid, in either of Bluesky's themes. Engagement numbers are decorative, as in every scheduler's preview.
- Does Bluesky cut the post off in the feed?
- Bluesky shows the whole post in the feed - nothing folds, so the 300-character limit is the only cut.
- How long can a Bluesky post be?
- 300 characters. Counted in grapheme clusters: a flag or a skin-tone emoji is one character however many code points it is built from.
Where these numbers come from: our sourced Bluesky spec page, every figure carrying its citation and the date we last checked it.

We built these because our own agents count against exactly these limits before they publish. Let them write the post too.
