Why teams schedule Instagram with PostBoost

One calendar for every channel

See Instagram next to your other 14 channels and move posts when plans change.

One post, a version per network

Write once, then adjust the text for Instagram without copying the post.

Know when a post fails

If Instagram rejects a post, you see why and can retry it once it is fixed. A webhook can tell your code too.

Hashtag limit checked

Instagram allows 5 hashtags per post. PostBoost flags a caption with more before it is published.

Instagram on PostBoost in one paragraph

PostBoost schedules and publishes to Instagram: post, reel and story. You connect it by signing in with Instagram or through a linked Facebook Page. Posts go out from the dashboard, from an AI agent over MCP or from the REST API, and each connected Instagram account counts toward your plan's social accounts (Free: 3).

Questions about Instagram

Do I need an Instagram business account?

You need a professional account, Business or Creator, because Instagram only allows publishing to those. With Instagram login no Facebook Page is needed. With Facebook login the account must be linked to a Facebook Page.

How many hashtags can I use?

5 per post. PostBoost checks the caption before it goes out.

Can I add a first comment?

Not on Instagram yet. Meta has to approve the comment permission for our app first. The post itself publishes normally.

Can I connect Instagram on the Free plan?

Yes. Every plan can connect Instagram. The Free plan includes 3 social accounts and 3 scheduled posts. Paid plans start at $29 a month with a 14-day free trial.

Can my AI agent post to Instagram?

Yes. Connect PostBoost to Claude, ChatGPT, Cursor or another MCP client, then ask it to write or schedule a Instagram post. Posts stay drafts until you or the agent schedule them.
