Rubinyun

Rubinyun is an API-first Instagram scheduler built for automations. Instead of generic "best time" averages, it reads the engagement of your own recent posts through the Instagram Graph API and works out the best hour for each weekday of your audience. It publishes images, carousels, reels and stories, and keeps running on its own even with your PC off. The meter is what makes it different: almost everyone else charges per connected profile, so the bill grows with the number of accounts whether they post or not. Rubinyun charges per published post. Ten profiles cost the same as one, and if Instagram rejects a post you are not charged for the attempt. It fits n8n, Make, or any HTTP client (a ready-made n8n template is provided), and there is a free plan with the API included. Best for freelancers and agencies with several client profiles that each post a few times a month.
