Apps that post your Shopify products to Instagram

What to look for

Ask four questions: what does the tool make from a product (an image, a designed post, a video), which networks does it post to, do you see each post before it goes out, and how is it priced. All facts below are from each vendor’s own site or Shopify App Store listing on 19 October 2026, in USD.

1. Synapis: designed posts you approve, no subscription

Synapis reads your website for your brand and your Shopify catalogue for best sellers, offers and new arrivals, then makes each post, caption and a matching design, and sends it to you to approve. It posts to Instagram, Facebook and LinkedIn, and makes image posts, not video. You connect it with a custom app in your Shopify admin rather than an App Store install. 3,000 free credits, then packs from $9.90.

2. Outfy: the most formats on autopilot

Outfy turns products into videos, UGC-style clips, collages, promotions and review posts and schedules them across seven networks, rotating products and skipping sold-out ones. It is rated 4.8 from 573 reviews on the App Store and has a free-forever plan; paid plans list at $25 to $55 a month. Its pages describe previews but no approval step.

3. Predis.ai: an AI content suite with a Shopify side

Predis.ai makes product posts, carousels and product videos from your store and lists ten publishing channels. Its Core plan ($32 a month, or $230 a year) has no auto posting; auto posting starts on Rise. It lists approval workflow tools and competitor analysis, with a 3-day trial.

4. AI Auto Post: the cheapest start

AI Auto Post by DevCloud runs posting campaigns on the products, platforms and times you pick, with AI captions and product images. Plans are $2.99, $4.99 and $9.99 a month with a 5-day trial; Instagram and Facebook on Basic, Pinterest and X from Standard. It had 5 reviews, averaging 3.6, when we checked.

5. Postify: one product a day, fully hands-off

Postify posts your Shopify products to Facebook and Instagram every day, up to four posts a day, with AI captions written by Claude and slideshow videos, and waits 350 days before repeating a product. One plan at $49 a month after a 14-day trial. Its site says "you do nothing"; it describes no approval step.

Which one to choose

If you want video and many networks running on their own, look at Outfy or Predis.ai. If you want the lowest price and are happy to set up campaigns, AI Auto Post. If you want one hands-off post a day on Facebook and Instagram, Postify. If you want posts designed in your own brand that you approve before they go out, with no subscription, start with Synapis.
