Plan, preview and publish Instagram and Facebook posts from inside Sanity Studio, through the Zernio API. Posts live in the dataset as documents, so they get drafts, version history, roles and a reference to the article or release they belong to. The tool adds a cockpit with a calendar, a filtered post list, true-to-scale previews per post type, and a settings panel for the API key, profiles and connected accounts. Covers Instagram feed, carousel, story and reel plus Facebook feed, story and reel, with per-type validation while writing.
