How Bluesky posting works
Bluesky is a direct provider that publishes once you connect an account and opt in. RostrumPost builds the native variant and checks it against the 300 character limit during preflight.
Because external publishing is opt-in, you can build and preview the full flow with safe mock providers before anything goes live.
