What is ONYX?

ONYX is a social scheduler built specifically for Bluesky rather than adding it as an afterthought, aimed at creators, founders and small businesses establishing a presence there. It handles drafting, a weekly scheduled queue, thread planning, AI-assisted idea generation trained on your own voice, and performance review from a single calendar. A free plan is available without a credit card.

The single-platform focus is the whole proposition, and it cuts both ways. Bluesky remains substantially smaller than the established networks and most general schedulers support it thinly if at all, so a dedicated tool gives features the big suites do not. Against that, you will need something else for every other channel, so ONYX makes sense as a specialist addition rather than a replacement for your main scheduler. Verify current plan limits directly, since independent coverage is limited.

Use Cases

Maria, a freelance writer, drops a rough morning thought into ONYX and picks one of three AI drafted variations, scheduling it for her best performing 10am slot in under a minute.

Jordan, a solo SaaS founder, uses the bulk CSV upload to queue an entire month of product update posts in one sitting instead of logging in daily.

Priya, a community manager, builds a six post thread from a single long form idea using the AI thread composer, which auto splits her text without cutting words mid sentence.

Tom, a creator with three BlueSky accounts, switches between his personal, podcast, and newsletter profiles inside the Studio plan instead of juggling separate logins.

Aisha, a marketing consultant, checks the insights suite every Monday to see who unfollowed her and which hashtag combos drove the most replies that week.
