What Postline does
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.
How it works
- Add channels and upload media to the library.
- Write a post and check it against each platform's limits.
- Send it for review and approve it.
- Schedule it; at the scheduled time Postline delivers it to the channel's sandbox and shows the status per channel.

Good to know
- 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.
Your data
- Postline never posts through unofficial means, and never labels a sandbox result as published.
- Passwords are stretched in your browser (PBKDF2) and only a salted hash is stored; the plain password is never sent.
- Each workspace's data is isolated from other workspaces, and you can export your workspace data or delete your account.
- Paid third-party providers are off by default, and sandbox and test-mode results are always labelled as such.
Questions and answers

Which platforms does Postline check posts for?
Instagram, TikTok, LinkedIn, X, Facebook and YouTube, using configured limits taken from each platform's public documentation.
Can a post go out without approval?
No. Posts move from draft to review to approved before they can be scheduled.
Is Postline free to use?
Yes, there is a Free plan with no card needed: 30 scheduled posts per month, 500 MB of media library, 3 connected channels. Starter costs USD 29 per month and Pro costs USD 99 per month, with higher limits. Paid checkout is not switched on yet, so paid plans cannot be bought for now.
