# Postline

> Postline plans, approves and schedules social posts on one calendar, checks each post against platform limits, and publishes only through official APIs.

Postline is a web app, in private beta. Who it is for: Teams and businesses that plan social posts and want an approval step before anything goes out.

- One calendar for drafts, reviews, approvals and scheduled posts, with a shared media library.
- Checks each post against configured per-platform limits for Instagram, TikTok, LinkedIn, X, Facebook and YouTube.
- Approval workflow: posts go from draft to review to approved before they can be scheduled.
- Delivery status per channel, with retry on failure.

Plans (prices in USD): Free: 30 scheduled posts per month, 500 MB of media library, 3 connected channels; Starter, USD 29 per month: 300 scheduled posts per month, 5,000 MB of media library, 10 connected channels; Pro, USD 99 per month: 3,000 scheduled posts per month, 50,000 MB of media library, 50 connected channels. Paid checkout is not switched on yet, so paid plans cannot be bought for now.

Limitations:
- Publishing is in sandbox mode: channels are not connected to the real platforms, and nothing is posted. A delivered post shows "Sandbox accepted, not posted to any platform".
- Live publishing will use each platform's official API, and only after that platform approves the app.
- No engagement analytics yet: the counts shown are delivery counts.
