300 characters is unforgiving
Bluesky counts graphemes strictly. Cross-posting from X or Threads without rewriting routinely hits the ceiling and fails at publish.

Publish to Bluesky automatically
Bluesky's open social graph runs on AT Protocol with a hard 300-grapheme cap and anti-marketing culture. Content Drifter generates native-feeling posts, connects via app password, and auto-publishes on Pro.
3 reasons publishing to Bluesky manually is broken
OAuth is not shipped yet
Third-party apps connect with app-scoped passwords today. Many schedulers skip Bluesky entirely because the connect flow feels unfamiliar.
Marketing tone gets muted
The Bluesky community down-ranks obvious promo copy. Posts need to sound conversational, not like LinkedIn thought leadership.

Frequently asked questions
How do I publish to Bluesky automatically?
On Pro, open Platforms, connect Bluesky with your handle and an app password from bsky.app/settings/app-passwords, generate a post under 300 characters, and schedule or publish.
Is Bluesky auto-posting against Bluesky terms?
App passwords exist specifically for third-party clients. You authorize write access and can revoke it independently of your main password.
Why does Content Drifter use an app password instead of OAuth?
Bluesky's OAuth for third parties is planned but not broadly available yet. App passwords are the supported connect method today.
Can I attach images or video on Bluesky?
Yes — up to four images (JPEG/PNG/WebP, ≤2 MB each) or one MP4 video (≤100 MB, ≤60 s) per post, matching AT Protocol lexicon limits.
What is the Bluesky character limit?
300 graphemes combined for content and hashtags. Content Drifter validates before publish so posts do not fail at the API.
