Instagram Post Scheduler to Schedule Instagram Posts, Reels & Stories

Yes. Connect an Instagram Business or Creator account, pick a slot on the drag-and-drop calendar, and your image, video, or carousel publishes automatically through the official Instagram Graph API. Captions can run up to 2,200 characters and you can queue weeks of posts in a single session.

Yes. Upload an .mp4 in the editor and Postiz publishes it as a Reel at your scheduled time through Instagram's Graph API. Stories are scheduled as native single-media posts for images or video, and multi-frame sets publish as separate Stories automatically, so you do not have to log back in at post time.

Yes. Add multiple images or videos to a single Instagram post in Postiz and they publish as a native carousel through the Graph API. Write one caption up to 2,200 characters, set the order of slides, and preview the final post before it goes live.

Instagram's API requires a Business or Creator account connected to a Facebook Page, so personal accounts cannot schedule. Postiz flags common issues (non-business account, revoked token, unsupported aspect ratio outside 4:5 to 1.91:1, or the 25 posts per day Graph API cap) with a clear message so you can fix and reschedule.

Yes. The built-in Postiz AI agent drafts captions in your tone, suggests hooks, and generates on-brand images from a text prompt. It can also produce AI video via Veo3 or the image-text-slides mode, and drop the whole set straight into your Instagram schedule.

Yes. Write one post in the Postiz composer, pick the channels you want, and the same media publishes to Instagram, TikTok, YouTube Shorts, Facebook, and 30+ other networks. Each channel keeps its own caption variant, so you can tweak copy per platform without duplicating work.

Yes. Postiz gives you a week and month drag-and-drop calendar view of every scheduled Instagram post, Reel, Story, and carousel, alongside your other channels. Move a post to a new slot by dragging it, set up recurring time slots from one day to one month apart, and auto-repost evergreen content on a recycle schedule.

Yes. Postiz ships a public REST API (POST /public/v1/posts) to schedule Instagram content programmatically, plus webhooks for GET/POST/PUT/DELETE events so you can plug into Zapier, Make, or your own stack. There's also an MCP server that lets AI assistants like Claude or Cursor schedule Postiz posts over OAuth.

Yes. Postiz starts with a 7-day free trial on signup, so you can connect your Instagram Business or Creator account, schedule Reels, Stories, and carousels, test the AI captions and media library, and see per-post reach and engagement analytics before picking a plan.
